My Asthma Free Forever Review

Highly Recommended

The author presents a well detailed summery of the major headings. As a professional in this field, I must say that the points shared in this manual are precise.

I give this ebook my highest rating, 10/10 and personally recommend it.

Theophylline and other xanthines

A retrospective analysis of 3995 patients treated with azithromycin did not show any pharmacokinetic interactions in patients who were also taking various other drugs, including theophylline (1,45). In two double-blind, randomized, placebo-controlled studies there was no inhibition of the metabolism of theo-phylline by azithromycin (53,54). However, there has been a report of reduced theophylline concentrations after withdrawal of azithromycin (55). The authors concluded that the mechanism of interaction was best explained by concomitant induction and inhibition of theophylline metabolism by azithromycin, followed by increased availability of unbound enzyme sites as azithro-mycin was cleared from the system.

Anti Asthmatic Activity

Early reports indicated that acute inhalation increased airway patency in healthy individuals (Tashkin et al., 1973 Vachon et al., 1973 Shapiro and Tashkin, 1976) and improved specific airway conductance in asthmatics (Tashkin et al., 1974, 1975b Vachon et al., 1976). However, there is good evidence that chronic smoking of cannabis restricts the airways and that, as with tobacco, unspecified irritants in the smoke can cause bronchospasm (Henderson et al., 1972). Aerosolised preparations of THC have produced bronchodilation in both healthy individuals and asthmatics (Tashkin et al., 1974, 1975a Abboud and Sanders, 1976 Williams et al., 1976) but in asthmatic subjects, bronchoconstriction has also been observed. For example, Abboud and Sanders (1976) administered aerosolised THC to six asthmatic patients, three of whom showed increases in specific airway conductance indicating bronchodilation the remaining three subjects showed a decrease in conductance and the overall mean, excluding...

Bronchodilators Sympathomimetic

A bronchodilator is a drug used to relieve bron-chospasm associated with respiratory disorders, such as bronchial asthma, chronic bronchitis, and emphysema. These conditions are progressive disorders characterized by a decrease in the inspiratory and expiratory capacity of the lung. Collectively, they are often referred to as COPD. The patient with COPD experiences dyspnea (difficulty breathing) with physical exertion, has difficulty inhaling and exhaling, and may exhibit a chronic cough. The two major types of bronchodilators are the sym-pathomimetics and the xanthine derivatives. The anti-cholinergic drug ipratropium bromide (Atrovent) is used for bronchospasm associated with COPD, chronic bronchitis, and emphysema. Ipratropium is included in the Summary Drug Table Bronchodilators. Chapter 25 Examples of sympathomimetic bronchodilators include albuterol (Ventolin), epinephrine (Adrenalin), salme-terol (Serevent), and terbutaline (Brethine). Many of the sympathomimetics used as...

Drug Drug Interactions Theophylline

An interaction of pyrantel with theophylline has been reported (3). An 8-year-old boy with status asthmaticus was given intravenous aminophylline and then switched to mod-ified-release oral theophylline on day 3, when his serum theophylline concentration was 15 mg ml. On day 4 he was given a single dose of pyrantel 160 mg (for A. lumbricoides infection) at the same time as his second oral dose of theophylline. About 2.5 hours later his serum theophylline concentration was 24 mg ml, and a further 1.5 hours later it had risen to 30 mg ml. No further theophylline was given and no theophylline toxicity occurred.

Cromoglycate nedocromil and lodoxamide

Sodium cromoglycate is widely used in the prophylactic treatment of allergic diseases, especially bronchial asthma and allergic rhinitis. It inhibits histamine release from mast cells by a stabilizing effect on the cell membrane. It is usually given by inhalation or intranasally. The bioavailability following inhalation is low (

Therapeutic Drug Monitoring of Antiasthmatic Drugs

Theophylline is a bronchodilator and respiratory stimulant effective in the treatment of acute and chronic asthma. The drug is readily absorbed after oral absorption, but peak concentration may be observed much later with sustained release tablets. The bronchodilator effect of theophylline is proportional to the log of serum drug concentration over a range of 5-20 g mL (129). Adverse reactions may be observed at concentrations exceeding 20 g mL. However, serum therapeutic concentrations between 10 and 20 g mL have also been reported (130). Theophylline is metabolized by hepatic cytochrome P450, and altered pharmacokinetics of theophylline in disease states have been reported. Clearance of theophylline is slow in neonates compared with that in adults, while theophylline metabolism is also altered in hepatic disease. Acute viral illness associated with fever may prolong the half-life of theophylline (131). Patients with pneumonia and episodes of severe airways obstruction also may...

The safety of fenoterol in severe asthma

Debate continues about the safety of fenoterol in the treatment of severe asthma. A sharp rise in asthma mortality in 1977 in New Zealand provoked debate about the safety of beta2-adrenoceptor agonists, especially the short-acting compound fenoterol. This led to the withdrawal of fenoterol in New Zealand and amendment of the American Asthma Guidelines, suggesting caution in the regular use of beta2-adrenoceptor agonists (1). Although there is evidence linking fenoterol to increased morbidity and mortality in asthma (2), the underlying mechanisms were not known. It was suggested that the increase in mortality might be linked to fatal cardiac dysrhythmias, developing under conditions of asthma-induced hypoxia and high doses of beta2-adrenoceptor agonists (3). In a report the manufacturers have discussed the epi-demiological data linking the use of fenoterol to asthma mortality in New Zealand. They pointed out that asthma mortality started to fall in 1979 while fenoterol sales were still...

Theophylline and St Johns Wort

A 42-year-old female taking an unusually high dose of theophylline (1600 mg per day) indicated that prior to her recent hospitalization she was stabilized on a twice daily theophylline dose of 300 mg. This dosage produces a theophylline serum concentration of 9.2 g mL. The patient informed during interview that she was taking St John's wort (0.3 hypericin) 300 mg per day for the last 2 months. She had been decided to discontinue St. John's wort, and 7 days later her theophylline level was increased to 19.6 g mL and her dosage was consequently adjusted downwards (25). In vitro study with intestinal LS 180 cells indicted that St. John's wort increased the expression of CYP1A2 in a concentration-dependent manner, and this induction maybe responsible for reduced plasma theophylline concentrations upon co-administration of St. John's wort (26). However, Morimoto et al. (27) found no significant interaction between St. John's wort and theophylline where healthy volunteers consumed St....

Asthma and pregnancy

An increasing number of pregnancies (5-8 ) are complicated by asthma. The course and severity of asthma can change during pregnancy, and may improve, remain unchanged or worsen. Asthmatic women have an increased risk of pregnancy complications and adverse outcome, such as hypertensive disorders, preterm labor and delivery, intrauterine growth restriction, placenta praevia, cesarean delivery and low birth weight, especially when asthma is inadequately or poorly controlled (Beckmann 2003, Bracken 2003, Mihrshahi 2003, Wen 2001, Kallen 2000, Alexander 1998, Demissie 1998). However, when asthma is aggressively controlled and well-managed, there has been no reported association with adverse infant and maternal outcomes or asthma complicating pregnancies (Olescn 2001, jana 1995, Schatz 1995). Stenius-Aamiala and colleagues report that there is no serious effect on pregnancy outcome if an acute asthma attack is adequately treated (Stenius-Aamiala 1996). The risk of suffering an acute attack...

Bronchial asthma

Beta-adrenoceptor antagonists should not be given to patients with bronchial asthma or obstructive airways disease, unless there are no other treatment options, because of the risk of precipitating bronchospasm resistant to bronchodilators. Celiprolol, a beta1-antagonist with beta2-agonist activity, has a theoretical but unproven advantage. Alternatively, cardioselective drugs should be chosen in the lowest possible dosages and in conjunction with a beta2-adrenoceptor agonist, such as salbutamol or terbutaline, to minimize bronchoconstriction.


Fluoroquinolones are potent inhibitors of hepatic cyto-chrome P450 isozymes (150). They inhibit theophylline metabolism, and accumulation of theophylline has led to seizures (151). Theophylline clearance is reduced by about 10 by norfloxacin, 30 by ciprofloxacin, and 70 by enoxacin (152-162). In a comparison of grepa-floxacin (400 and 600 mg day) and ciprofloxacin, increased theophylline concentrations associated with clinical symptoms were found with both doses of grepa-floxacin but not in patients taking ciprofloxacin (17). The dosage of theophylline should be reduced when a quino-lone is given.

Antiasthma Drugs

Asthma is a respiratory condition characterized by recurrent attacks of dyspnea (difficulty breathing) and wheezing caused by spasmodic constriction of the bronchi. With asthma, the body responds with a massive inflammation. During the inflammatory process, large amounts of histamine are released from the mast cells of the respiratory tract, causing symptoms such as increased mucous production and edema of the airway and resulting in bronchospasm and inflammation. With asthma the airways become narrow, the muscles around the airway tighten, the inner lining of the bronchi swell, and extra mucus clogs the smaller airways. (See Fig. 37-1.) Along with the bronchodilators, several types of drugs are effective in the treatment of asthma. These include corticosteroids, leukotriene formation inhibitors, leukotriene receptor agonists, and mast cell stabilizers. Antiasthma drugs are used in various combinations to treat and manage asthma. Using several drugs may be more beneficial than using a...


Bronchodilators are drugs that open the airways in the respiratory tract. They are widely prescribed as pills and aerosol inhalers to patients with asthma to relieve the wheezing and difficulty in breathing characteristic of that disease. Most of these drugs work by stimulating the sympathetic nervous system, which regulates the muscular walls of the bronchial tubes. As a result, in addition to their desired effect, they commonly cause stimulation, anxiety, jittenness, and insomnia. Patients often dislike these side effects but have no alternatives to the drugs if they want to breathe. Another problem with the stimulant bronchodilators is their strong tendency to cause dependence. When the effect of a dose wears off, bronchial constriction increases as a reaction to the drug, making further doses necessary. Asthmatics frequently m- hide bronchodilators throughout the day, in addition to taking them regularly by mouth. This frequency of use increases risks of addiction and mood change....


Although cannabis was used as a bronchodilator in the nineteenth century, modern human research seems to have been limited to a brief period in the 1970s. Small controlled studies in asthmatic volunteers (Tashkin et al. 1974 Williams et al. 1976 Tashkin et al. 1977) showed that oral, smoked and aerosolised THC had significant bronchodilator activity comparable to that of salbutamol, though slower in onset. Dose-related tachycardia and intoxication occurred at higher doses. An inhaled aerosol avoided systemic absorption of THC but induced cough and chest discomfort, which limited its usefulness.

Organs and Systems Respiratory

Aerosol therapy with acetylcysteine can cause broncho-constriction. In 31 ambulant asthmatics using 10 acet-ylcysteine solution, there was a mean reduction of 55 in the FEV1 in 19 subjects. The addition of 0.05 isoprena-line reduced the number of patients who developed bronchoconstriction from 19 to 5 (SEDA-5, 170). In two placebo-controlled studies, involving over 700 patients, there was no difference in adverse effects between oral acetylcysteine and a placebo. There was, however, no improvement in FEV1 in these studies (3).

General Information

Depending on the criteria used, the incidence of aspirin hypersensitivity is variously estimated as being as low as 1 or as high as 50 , the highest frequency being found in asthmatics. The condition is characterized by bronchospasm (asthma), urticaria, angioedema, and vasomotor rhinitis, each occurring alone or in combination, often leading to severe and even life-threatening reactions. There is no clear evidence of an association with tumors, apart from the possible peripheral contribution of aspirin to the development of urinary tract neoplasms in patients with analgesic nephropathy. Indeed, some authors have suggested a role for salicylates in reducing the incidence of color-ectal tumors and breast tumors.

Drug Administration Drug administration route

Intracoronary adenosine has been compared with intravenous adenosine for the measure of fractional flow reserve in 52 patients with coronary artery lesions (44). The intravenous dose was 140 micrograms kg minute and the intracoronary bolus dose was 15-20 micrograms to the right coronary artery and 18-24 micrograms to the left coronary artery. The two routes of administration were equally effective in measuring hyperemic flow, and adverse effects were limited to two patients who received intravenous adenosine one patient had severe nausea and one patient with asthma had an episode of bronchospasm.

Factors affecting serum drug concentrations

The serum concentration of a particular drug is determined by absorption, distribution, metabolism, and excretion of a drug. Major characteristics that affect serum drug concentrations include genetic make up of a patient as well as age, gender, weight, habits (such as smoking), and diet. Elderly and newborns may metabolize a particular drug more slowly than others. Some drugs, for example theophylline, distributes to lean weight only where other drugs, such as phenytoin, distributes to total weight. Diseases may alter serum drug concentrations dramatically. Hepatic disease may alter metabolism of a drug where a patient with renal failure may clear a drug in urine more slowly than a patient with normal renal function. Pregnancy alters metabolism of several drugs while drug-drug interactions may also significantly alter serum drug concentrations.

Nursing Responsibilities

The primary nursing responsibility is to provide the patient with proper instructions for administering the drug. For example, many patients with asthma use a metered-dose inhaler to dilate the bronchi and make breathing easier. Without proper instruction on how to use the inhaler, much of the drug can be deposited on the tongue, rather than in the respiratory tract. This decreases the therapeutic effect of the drug. Instructions may vary with each inhaler. To be certain that the inhaler is used correctly, the patient is referred to the instructions accompanying each device. Figure 2-9 illustrates the proper use of one type of inhaler.

Cardiovascular Disease and Serum Drug Concentration

Cardiac failure is often associated with disturbances in cardiac output, influencing the extent and pattern of tissue perfusion, sodium and water metabolism as well as gastrointestinal motility. These factors affect absorption and disposition of many drugs requiring dosage adjustment. Vd and clearance of lidocaine are decreased in cardiac failure. For drugs that are metabolized by the liver, decreased blood flow in the liver accounts for reduced clearance, but impaired hepatic metabolism in these patients also plays a role. Accumulation of active metabolites of lidocaine and procainamide in these patients are clinically significant. Theophylline metabolism, which is largely independent of hepatic blood flow, is reduced in patients with severe cardiac failure and dose reduction is needed. Digoxin clearance is also decreased. Quinidine plasma level may also be high in these patients because of lower Vd (89). Elimination halflife is directly related to the Vd and inversely related to...

Therapeutic drug monitoring of individual drugs

Usually, concentration of a therapeutic drug is measured in the serum or plasma. However, whole blood concentration of immunosuppressant drugs such as cyclosporine and tacrolimus is usually measured for therapeutic drug monitoring. Obtaining blood for measurement of a drug during the absorption or the distribution phase may lead to misleading information. Moreover, to measure the peak concentration of a drug, timing of the sample will depend on the route of administration. After intravenous administration, the peak concentration of a drug may be achieved in a few minutes. On the contrary, for a sustained release tablet, the mean time to reach the peak plasma concentration of theophylline was 7.9 h in one study (106). The trough concentration is clinically defined as the serum drug concentration just before the next dose. Usually, trough concentrations are monitored for most drugs, but for aminoglycosides and vancomycin, both peak and trough concentrations are monitored. For a...

Ineffective Therapeutic Regimen Management

When working with a patient who is not managing the drug regimen correctly, the nurse must ensure that the patient understands the drug regimen. It is essential to provide written instructions. If possible, the nurse should allow the patient to administer the drug before he or she is dismissed from the health care facility. The nurse should determine if adequate funds are available to obtain the drug and any necessary supplies. For example, when a bronchodilator is administered by inhalation, a spacer or extender may be required for proper administration. This device is an additional expense. A referral to the social services department of the institution may help when finances are a problem.

Observational studies

Appearance of TNF alfa in the plasma during the 3 hours after the start of antibody infusion, suggesting that they resulted from cytokine release. There was systolic hypotension, defined as a systolic pressure below 90 mmHg and a fall of at least 20 mmHg, in one patient who was given 10 mg. There were non-specific skin rashes in one patient in each of the groups who were given 10, 30, and 100 mg and in three of those given 300 mg. There were three serious adverse events fatal rupture of an aortic aneurysm, thought to be unrelated to the drug, an episode of severe reversible airways obstruction in a patient with asthma, and an episode of unexplained collapse, presumed to be vasovagal, followed by full recovery several hours after the end of the first infusion. No opportunistic or other infections were reported.

Placebocontrolled studies

Oral bambuterol 20 mg at night has been compared with inhaled salmeterol 50 mg bd for persistent nocturnal symptoms in 117 asthmatics already taking inhaled corticoster-oids in a randomized, double-blind, placebo-controlled trial for 6 weeks (2). The treatments resulted in significant and equivalent improvements in nocturnal and daytime asthma symptoms, peak flow, and the use of short-acting beta-adrenoceptor agonists. Drug-related adverse events included headache (six with bambuterol, two with salme-terol), tremor (three in each group), cramps (two with bambuterol), and palpitation (three with bambuterol, one with salmeterol). Four patients taking bambuterol withdrew owing to possible drug-related adverse effects (insomnia, headache, flushing, and mental excitation) compared with one patient taking salmeterol (tremor). Bambuterol appears to be a safe and effective alternative to inhaled long-acting beta2-adrenoceptor agonists for poorly controlled nocturnal symptoms in asthma.

Organs and Systems Cardiovascular

A retrospective study of prescriptions from three cohort studies suggested a possible adverse effect of oral bambuterol cardiac failure. A cohort of 12294 patients who received at least one prescription for nedocromil acted as the control group and was compared with 15 407 patients given inhaled salmeterol and 8098 patients given oral bambuterol. Questionnaires were sent to each prescriber asking for details of significant medical events after the first prescription (prescription event monitoring). From this information, rates and relative risks of non-fatal cardiac failure and ischemic heart disease were calculated. The age- and sex-adjusted relative risk of nonfatal cardiac failure associated with bambuterol was 3.41 (CI 1.99, 5.86) compared with nedocromil. When salme-terol was compared with nedocromil the relative risk for developing non-fatal cardiac failure was 1.1 (CI 0.63, 1.91). The adjusted relative risks of non-fatal ischemic heart disease with bambuterol and salmeterol...

Saliva and tears alternative to serum for therapeutic drug monitoring

Drugs that are not ionizable or are un-ionized within the salivary pH range (phenytoin, carbamazepine, and theophylline) are candidates for salivary therapeutic drug monitoring (102). Salivary flow rates vary significantly between individuals and under different conditions. The use of stimulated saliva has advantage over resting saliva. The salivary flow rate, pH and sampling condition, and other pathophysiological factors may influence the concentration of a particular drug in saliva. However, under well-controlled and standardized conditions, saliva can be used as an alternative matrix for monitoring of carbamazepine, phenytoin, primidone, and ethosuximide. One report also concluded that monitoring of salivary phenytoin and carbamazepine proved to be a realistic alternative to plasma-free level monitoring because excellent correlations were found between salivary levels and serum-unbound levels of both phenytoin and carbamazepine (103). However, a poor correlation was observed...

Identification of susceptible patients

An alternative explanation for the epidemic of asthma fatalities among users of beta-adrenoceptor agonist aerosols postulates the existence of a subset of asthmatic patients who are more sensitive than others to an adverse effect of beta-agonists. In this view the occurrence of a peak incidence of deaths will eliminate this subset and the overall death rate will thus fall once more without a proportionate reduction in the use of beta-agonists. A subset of asthmatic patients who develop a significant reduction in bronchodilator response to salbutamol after a short period of treatment has indeed been identified, although the number of patients studied was small. The subset developed a significant reduction in the Bmax for beta2-adrenoceptors in the lung. This was measured in vivo by PET scanning using a beta-antagonist ligand. Patients in the subset were homozygous for glycine at codon 16 on the beta2-adrenoceptor gene (SEDA-21,180). However, another and larger study failed to identify...

General adverse effects

The adverse effects of beta-blockers are usually mild, with occurrence rates of 10-20 for the most common in most studies. Most are predictable from the pharmacological and physicochemical properties of these drugs. Examples include fatigue, cold peripheries, bradycardia, heart failure, sleep disturbances, bronchospasm, and altered glucose tolerance. Gastrointestinal upsets are also relatively common. Serious adverse cardiac effects and even sudden death can follow abrupt withdrawal of therapy in patients with ischemic heart disease. Most severe adverse reactions can be avoided by careful selection of patients and consideration of individual beta-blockers. Hypersensitivity reactions have been relatively rare since the withdrawal of practolol. Tumor-inducing effects have not been established in man.

Partial agonist activity

Partial agonists, such as acebutolol, oxprenolol, pindo-lol, practolol, and xamoterol, produce less resting brady-cardia. It has also been claimed that such agents cause a smaller increase in airways resistance in asthmatics, less reduction in cardiac output (and consequently a lower risk of congestive heart failure), and fewer adverse effects in patients with cold hands, Raynaud's phenomenon, or intermittent claudication. However, none of these advantages has been convincingly demonstrated in practice, and patients with bronchial asthma or incipient heart failure must be considered at risk with this type of compound.

Adverse Reactions

Gastric upset, heartburn, nausea, vomiting, anorexia, and gastrointestinal bleeding may occur with salicylate use. Although these drugs are relatively safe when taken as recommended on the label or by the primary health care provider, their use can occasionally result in more serious reactions. Some individuals are allergic to aspirin and the other salicylates. Allergy to the salicy-lates may be manifested by hives, rash, angioedema, bronchospasm with asthma-like symptoms, and ana-phylactoid reactions.

Pharmacokinetic interactions

Lipophilic beta-adrenoceptor antagonists are metabolized to varying degrees by oxidation by liver microso-mal cytochrome P450 (for example propranolol by CYP1A2 and CYP2D6 and metoprolol by CYP2D6). These agents can therefore reduce the clearance and increase the steady-state plasma concentrations of other drugs that undergo similar metabolism, potentiating their effects. Drugs that are affected in this way include theo-phylline (393), thioridazine (394), chlorpromazine (395), warfarin (396), diazepam (397), isoniazid (398), and fle-cainide (399). These interactions are most likely to be of clinical significance when the affected drug has a low therapeutic ratio, for example theophylline or warfarin.


All narcotic analgesics are contraindicated in patients with known hypersensitivity to the drugs. These drugs are contraindicated in patients with acute bronchial asthma, emphysema, or upper airway obstruction and in patients with head injury or increased intracranial pressure. The drugs are also contraindicated in patients with convulsive disorders, severe renal or hepatic dysfunction, acute ulcerative colitis, and increased intracranial pressure. The narcotic analgesics are Pregnancy Category C drugs (oxycodone, Category B) and are not recommended for use during pregnancy or labor (may prolong labor or cause respiration depression of the neonate). The use of narcotic analgesics is recommended during pregnancy only if the benefit to the mother outweighs the potential harm to the fetus.

And Antiretroviral Drugs

Immunoassays are commercially available for TDM of antiasthmatic drugs theophylline and caffeine. The manufacturer of the FPIA assay for determination of total tricyclic antidepressants (TCA) in serum only recommends this assay for screening of TCA in serum in a patient with suspected overdose and cautions against using this assay for routine TDM of TCA. A patient overdosed with carbamazepine may show a falsely elevated TCA level if the FPIA assay is used because of cross-reactivity of carbamazepine with the antibody used in this immunoassay (39,40). Both HPLC and GC or GC combined with mass spectrometry can be used for routine TDM of various TCA. Methods for TDM of TCA are discussed in detail in Chapter 8. Recently, Wille et al. (41) reported HPLC and GC MS analysis of 13 new-generation antidepressants (venlafaxine, fluoxetine, viloxazine, fluvoxamine, mianserin, mirtazapine, melitracen, reboxetine, citalopram, maprotiline, sertraline, paroxetine, and trazodone) together with eight...

Susceptibility Factors Age

Xanthines have been given to infants at the risk of sudden infant death syndrome or idiopathic apnea of prematurity (see monograph on Theophylline). About 50 of 30 infants treated with caffeine (and 12 of 18 infants treated with theophylline) had significant increases in episodes of gastroesophageal reflux (36). The authors stressed that screening for reflux should precede the administration of caffeine (and theophylline) to infants at the risk of sudden infant death syndrome. As expected, the frequency of adverse effects such as tachycardia and gastroesophageal reflux is lower with lower doses of caffeine for example 2.5 mg kg qds (SEDA-17, 1).

USA Availability Prescription and nonprescription drug also in food Pregnancy Category C

Studies demonstrate caffeine can mildly help asthma sufferers. Theophyl-line, a drug commonly used to widen airways and help asthmatics breathe, is related to caffeine. Caffeine is a standard drug to help premature infants that have interruptions in breathing. Drawbacks. In the 1990s, 20 of the U.S. population was believed to be using over 700 mg of caffeine each day. That is enough to produce behavior mimicking an anxiety neurosis. If a person only ingests caffeine through pharmaceutical preparations or food products with labels listing caffeine amounts, intake can easily be measured. The amount in a restaurant cup of coffee is more difficult to measure one rule of thumb says 100 mg to 150 mg.

Psychological psychiatric

The Early Treatment of the Atopic Child (ETAC) Study has provided evidence that cetirizine may be able to halt the progression to asthma in high-risk groups of young children and infants with atopic dermatitis (9). However, the study involved giving relatively high doses of cetirizine to very young children (aged 1-2 years at study entry) over a long period of time. Therefore, the impact of prolonged use of high-dose cetirizine (0.25 mg kg bd over 18 months) on behavior and cognitive ability in young children and infants has been assessed in a double-blind, randomized, placebo-controlled study (10). Well-validated and standardized assessments of behavior or cognition were used, and the ages at which psychomotor milestones were attained were established. The authors concluded that, compared with placebo, cetirizine had no significant effects on behavior, cognition, or psychomotor milestones in young children with atopic dermatitis.

Potential Effects Of Airway Obstruction And Concurrent Lung Disease

Moreover, tumor masses within the airways are likely to cause changes in airflow patterns. Under these conditions, aerosol deposition in the airways and lungs deviates from that observed in healthy individuals, a scenario that is not unique to aerosol delivery for lung cancer treatment. Most marketed inhaler systems are designed for use in pulmonary diseases with varying degrees of obstruction and abnormal lung function (i.e. asthma, cystic fibrosis, etc.).

IL13 Modulators Clinical Data An

In a chronic model of Aspergillus fumiga-tus-induced allergic asthma, immunoneutral-ization of IL-13 has marked effects (555). The use of anti-IL-13 antibody results in a significant attenuation of airway hyperreactivity in this model. When IL-4 is neutralized, no statistically significant decrease was observed. In addition, neutralization of IL-13 inhibits collagen deposition, subepithelial fibrosis, and goblet cell hyperplasia. None of these effects was observed when neutralization of IL-4 was performed. Again, these results point to a broader spectrum of effects for IL-13 compared to that of IL-4, and for this reason IL-13 may be a more favorable target for asthma.

Pregnancy Category C

The drug was first isolated from coca plants in the mid-1800s. Cocaine apparently functions as an insecticide in the plants, but the substance has had no commercial agricultural use for that purpose. Early medical applications included administration to treat addiction to alcohol and opiates, but persons addicted to those drugs did not better on cocaine. Like many stimulants, cocaine has anorectic (weight-reducing) properties that decline as usage stretches over time but the drug's main medical use has been as a local anesthetic, particularly in ear, nose, and mouth surgery. Experimental use as an antide-pressant has been unsuccessful. Cocaine has been used to treat tonsillitis, earache, toothache, burns, skin rash, hay fever, asthma, hemorrhoids, nerve pain, nausea, and vomiting. It makes the body's immune system more active. For medical purposes cocaine has been largely superseded by drugs having less potential for abuse, but it is still called an excellent anesthetic for nose...

Contraindications Precautions And Interactions

Levodopa is used cautiously in patients with cardiovascular disease, bronchial asthma, emphysema, peptic ulcer disease, renal or hepatic disease, and psychosis. Levodopa and combination antiparkinsonism drugs (eg, carbidopa levodopa) are classified as Pregnancy Category C and are used with caution during pregnancy and lactation.

Pharmacokinetics And Glucodynamics

Formulation, a unique insulin delivery packaging, and a unique delivery device. Though they all may be characterized as inhaled insulin systems, these unique characteristics require us to individually scrutinize each product. The inhalers range from handheld breath actuated devices to meter dose inhalers similar to those used for asthma agents. Insulin delivery packaging ranges from dry-powder blister packs or capsules, to liquid blisters or liquid in asthma type canisters. Diverse particle technologies have also been investigated for the delivery of insulin. The Exubera and AERx systems were first technologies investigated in the 1990s.

Pituitaryadrenal axis

It has been said that Cushing-like effects are to be expected if the function of the adrenal cortex is suppressed by daily doses of more than 50 mg hydrocortisone or its equivalent. However, pituitary-adrenal suppression has been described at lower dosage equivalents, for example during prolonged intermittent therapy with dexamethasone (88). The secondary adrenal insufficiency caused by ther-apeutically effective doses can be observed even after giving prednisone 5 mg tds for only 1 week after withdrawal, adrenal suppression lasts for some days. If one continues this treatment for about 20 weeks, maximal atrophy of the adrenal cortex results, and lasts for some months. This effect begins with inhibition of the hypothalamus, and culminates in true atrophy of the adrenal cortex. It can occur even with glucocorticoids given by inhalation (89).

In a probable pharmacodynamic interaction, severe peripheral edema followed treatment with montelukast and prednisone for asthma (424). A 23-year-old man, with a history of asthma, house dust mite allergy, and rhinoconjunctivitis, presented with acute respiratory symptoms. He was given oral cetirizine, inhaled salmeterol, and fluticasone propionate, and oral prednisone 40 mg day for 1 week and 20 mg day for 1 week. His asthma recurred when prednisone was withdrawn and he took oral prednisone 60 mg day for 1 week and 40 mg day for 1 week. He also took mon-telukast 10 mg day. He then developed severe peripheral edema with a gain in weight of 13 kg. Prednisone

This substance is closely related to levorphanol and can produce a false positive for levorphanol in drug screen tests. The human body will transform part of a dextromethorphan dose into dextrorphan. The same transformation occurs in rats when comparing results in males and females, researchers found that a given amount of dextrorphan lasts twice as long in female rats. Drawbacks. Unwanted side effects may include nausea, vomiting, sleepiness, high or low blood pressure, uncontrollable eye movement, and hallucinations. Rat experiments show that high enough does can impair memory and learning. When one group of researchers tested dextrorphan's ability to prevent some types of brain damage, the scientists found instead that dextror-phan caused damage in rats.

Systemic availability of inhaled glucocorticoids

The extent of absorption of inhaled glucocorticoids tends to be less in asthmatic subjects than in healthy volunteers. In a study of fluticasone (500 micrograms via a dry powder device) in asthmatic patients with a wide range of severity, there was a highly significant linear correlation between lung function (expressed as percentage predicted FEVi) and the absolute magnitude of adrenal suppression (4). In 11 patients with moderately severe asthma (mean FEV1 54 predicted), who took fluticasone 1000 micro-grams day via a metered-dose inhaler with a spacer, the systemic availability of fluticasone was significantly less (10 ) than in 13 healthy controls (21 ). The plasma fluticasone concentrations (expressed as AUC) correlated positively with gas transfer (5). In contrast, there was no difference in plasma concentrations of fluticasone and budesonide between 15 mild asthmatics (mean FEV1 81 predicted) and healthy volunteers after inhalation of 1000 micrograms of either drug with single...

Local adverse effects

The local adverse effects of inhaled glucocorticoids have been studied in a prospective, cross-sectional, cohort study in 639 asthmatic children using beclomethasone (721 micrograms day) or budesonide (835 micrograms day) for at least one month (28). The local adverse effects included cough (40 ), thirst (22 ), hoarseness (14 ), dysphonia (11 ), oral candidiasis (11 ), perioral dermatitis (2.9 ), and tongue hypertrophy (0.1 ). A spacer doubled the incidence of coughing. A local myopathy caused by inhaled glucocorticoids can also cause dysphonia. However, patients with asthma have more dysphonia and vocal fold pathology than healthy controls and inhaled glucocorticoids can improve the voice in some patients (SEDA-21, 188).

Adrenal suppression by inhaled glucocorticoids in children

Inhaled glucocorticoids are being prescribed more and more in younger children at an earlier stage of their disease and for longer periods children with severe asthma are also treated with larger doses than licensed. Two girls aged 11 and 16 years, one boy aged 12 years, and one woman aged 54 years developed hypothala-mic-pituitary-adrenal axis suppression during treatment with inhaled fluticasone propionate 220880 micrograms bd for long-term control of asthma however, two of the patients also took oral prednisone or prednisolone (43). Because of poor growth, an 8-year-old girl's asthma medication was changed from budesonide to fluticasone propionate 250 micrograms day (44). However, 5 months later she had developed a round face. Her early morning cortisol concentration was less than 30 nmol l (reference range 140-720) and her growth had been no more than 0.5 cm during the past 5 months. Fluticasone propionate was discontinued. After 1 month, her Cushingoid features had resolved and...

CysLTl Antagonist Clinical Studies

Aerosolized SKF 104353, 100 and 800 jmg, shifted LTD4-induced bronchoconstriction by about 10-fold in normal and asthmatic individuals, respectively, when administered 2-3.5 h before challenge (242). The same dose protected against exercise-induced asthma (243). SKF 106203 was examined in normal volunteers and a 200 mg p.o. dose was effective in reducing LTD4-induced bronchoconstriction, with the maximal effect being observed 8 h after dosing (244). The Merck group has entered the greatest number of CysLTl antagonists into clinical studies. Extensive trials were performed with MK-0571 (L-660,711), its single enantiomer MK-0679, and with MK-0476. This compound montelukast (Singulair) has been approved for clinical use in the United States and internationally for the treatment of asthma in adults and children (245). Montelukast underwent extensive clinical testing. The studies used to support the clinical use of this agent have been reviewed in several venues (256-258). A daily oral...

Ongoing Assessment

Occasionally the patient may experience an acute bronchospasm either as a result of the disease, after exposure to an allergen, or as an adverse reaction to some antiasthma drugs, such as cromolyn inhalation. An inhaled sympathomimetic, such as albuterol, may be prescribed initially. Salmeterol, a long-acting p-ago-nist, is contraindicated because of its slowed onset of action. During an acute bronchospasm, the nurse checks the blood pressure, pulse, respiratory rate, and response to the drug every 15 to 35 minutes until the patient's condition stabilizes and respiratory distress is relieved.

Systemic availability of inhaled corticosteroids SEDA23175 SEDA24 185

Plasma concentrations have been measured in 13 healthy subjects and eight patients with mild asthma using inhaled fluticasone propionate 1000 g twice daily via Diskus or pressurized metered-dose inhaler and ofbudes-onide 1000 g twice daily via Turbuhaler for 7 days. 24-hour plasma cortisol concentrations were determined to assess the systemic activity of fluticasone propionate and budesonide. At steady state, the systemic availability of budes-onide via Turbuhaler (39 ) was significantly higher than that of fluticasone propionate via Diskus (13 ) or inhaler (21 ). Fluticasone propionate had a larger distribution volume and slower rates of absorption and clearance. Despite a significantly higher pulmonary availability of budesonide via Turbuhaler, plasma cortisol suppression was less than that offlu-ticasone propionate via inhaler and similar to that offluticasone propionate via Diskus. There were no differences between healthy subjects and patients with mild asthma in subgroup...

There is no pharmacological free lunch in cannabis or any drug. Negative reactions can result. A small percentage of people have negative or allergic reactions to marijuana. Heart patients could have problems, even though cannabis generally relieves stress, dilates the arteries, and in general lowers the diastolic pressure. A small percentage of people get especially high heart rates and anxieties with cannabis. These persons should not use it. Some bronchial asthma sufferers benefit from cannabis however, for others it may serve as an additional irritant.

Systemic effects of ophthalmic medications

The systemic effects exerted by eye-drops are most pronounced in the case of agonists and antagonists in the autonomic nervous system. For example, beta-blockers in eye-drops can cause bronchospasm, heart failure, syncope, and psychiatric disorders (4-6), especially at high doses and with non-selective beta-blockers, although these adverse reactions are usually related to failure to observe prescribing precautions (1).

Hypochlorite SED14 767

Respiratory Hypochlorite is widely used as a cleaning agent and to deal with blood spillages. Chlorine gas, which is released during the use of hypochlorite, can cause mucous membrane irritation, bronchospasm, pneumonia, and pulmonary edema. It is believed that the low concentrations of hypochlorite that are used as a cleaning substance do not cause respiratory damage.

Contraindications adverse effects precautions

- Nebulised salbutamol should be reserved for severe asthma attacks when inhalation of oxygen is also required. Otherwise, salbutamol should be delivered via a metered-dose inhaler with a spacer administration is easier and faster, the treatment is as effective, or even more effective, than with a nebuliser and causes fewer adverse effects.

Pregnancy Category None

Effects are similar to those of belladonna. Drugs found in jimson weed leaves, flowers, and seeds include atropine, hyoscyamine, and scopolamine, which are often called belladonna alkaloids. Folk medicine preparations from jimson weed flowers are put on bruises, wounds, or insect bites to diminish discomfort leaves and roots are used in a similar way and also to treat boils. A drink from the plant is given to help people endure the pain of setting broken bones. Inhaling jimson weed smoke is a traditional remedy for asthma, sore breathing, or coughing. Vapor from boiling the substance is used for the same purposes. Scientific measurement has confirmed that jimson weed smoke improves airway function of asthmatics. The natural product is also a treatment against cramps, eye inflammation, and feverish infection. The plant has been used as an aphrodisiac. Drawbacks. Jimson weed has anticholinergic actions, meaning it can change heartbeat, affect eyesight (including extreme and prolonged...

DrugSt Johns Wort Interactions Lower Concentrations of Therapeutic Drugs

John's wort may cause treatment failures due to significant reductions in plasma drug concentrations because of increase in clearance of drugs. Unrecognized use of St. John's wort is frequent among patients and may have important influences on the effectiveness and safety of drug therapy during hospital stay (23). Published reports indicate that St. John's wort significantly reduces steady-state plasma concentrations of cyclosporine, tacrolimus, amitriptyline, digoxin, fexofe-nadine, indinavir, methadone, midazolam, nevirapine, phenoprocoumon, squinavir, simvastatin, theophylline and warfarin (24). This long list of drugs includes immunosuppressant drugs (cyclosporine and tacrolimus), HIV protease inhibitors and HIV non-nucleoside reverse transcriptase inhibitors metabolized via CYP3A4. Increased clearance of oral contraceptives has also been reported.

Regulations and Guidelines

Globally, various guidelines for substance abuse management have been developed by government agencies, forensic societies, and clinical organizations. Some of the guidelines include more detailed technical and procedural recommendations for specimen collection and processing, initial drug screening, confirmation analysis, quality control and assurance, and documentation and result-reporting requirements.

Fooddrug Interactions

Food-drug interactions may be pharmacokinetic or pharmacodynamic in nature. Certain foods alter activity of drug metabolic enzymes, and especially CYP3A4 appears to be the key enzyme in food-drug interaction (94). It has also long been recognized that intake of food and fluid can alter the extent of drug absorption. This alteration may be related to alteration of physiological factors in the gut such as gastric pH, gastric emptying time, intestinal motility, hepatic portal blood flow or bile flow rate. Moreover, direct interaction of food with drug may also alter bioavailability such as adsorption of a drug in insoluble dietary component, complex formation of a drug with a metal ion or partitioning of a drug in dietary fat. Food may be able to alter performance of modified released oral formulation (95). It has been recognized that smoking, intake of charcoal-broiled food or cruciferous vegetables induce the metabolism of multiple drugs, whereas grapefruit juice increases...

See also Anticholinergic drugs General Information

Ipratropium hydrobromide is a quaternary amine, the semisynthetic isopropyl derivative of atropine, which has low lipid solubility and is poorly absorbed. It has anti-cholinergic properties and is used to treat asthma. Ipratropium has established a place in the therapy of asthma as an alternative to beta2-adrenoceptor agonist aerosols for patients who fail to respond adequately to these agents. Ipratropium may be more effective than beta2-adrenoceptor agonists for patients with non-atopic asthma and chronic bronchitis. It has been reported to augment the effects of beta2-adrenoceptor agonists when given by nebulized inhalation in acute asthma (2).

Beta Blocker Medications

Beta-adrenergic blockers competitively antagonize nore-pinephrine and epinephrine at the beta-adrenergic receptor (Table 4-2). It is thought that the majority of positive effects of beta-blockers are due to their peripheral (rather than central) actions. Beta-blockers can decrease many of the peripheral manifestations of anxiety such as tachycardia, diaphoresis, trembling, and blushing. The advent of more selective beta-blockers that only block the beta-2-adrenergic receptor has been beneficial since blockade of beta-1-adrenergic receptors can be associated with bronchospasm.

Organs and Systems Nervous system

There is considerable controversy about the frequency and severity of sedation. Although it is commonly reported when ketotifen is started (23 in one study), its incidence falls during the first 2 months to about 6 . Only 2-3 of patients discontinue therapy for this reason (8). In a study involving 1791 patients, with allergic paroxysmal asthma, somnolence occurred in 13 . This effect started early in treatment and wore off in more than one-third of the patients (2). A 3-month-old boy was given ketotifen, 0.1 mg kg day, for asthmatic bronchitis. After 10 days his facial movements altered and 1 month after ketotifen was started tonic spasms began. His seizures consisted of a sudden contraction, usually bilateral and symmetrical involving the muscles of the neck, trunk, and limbs. An electroencephalogram showed a hypsarrhythmic trace. He was treated with ACTH and clonazepam without benefit. Ketotifen was withdrawn and ACTH and clonazepam were replaced with valproic acid. This resulted...

Pregnancy Category D

In an experiment comparing mephobarbital to phenobarbital in epileptic children, parents reported fewer unwanted behavioral effects with mephobarbital, and some pediatricians agree with that observation. The most typical behavior problem in such children is hyperactivity. A formal test comparing the two drugs, however, found no difference in either unwanted conduct or therapeutic power. effectiveness of birth control pills and with actions of medicines used to control epilepsy and blood clotting. Drugs used to treat asthma, blood pressure, and heart ailment may not work as well if a person also takes mephobarbital. Cancer. Not enough scientific information to report.

Sympathomimetic Drugs

These drugs are used cautiously during pregnancy (epinephrine and apraclonidine, Pregnancy Category C dipivefrin, Pregnancy Category B) and lactation and in patients with hypertension, diabetes, hyper-thyroidism, heart disease, cerebral arteriosclerosis, or bronchial asthma. Some of these drugs contain sulfites that may cause allergic-like reactions (hives, wheezing, anaphylaxis) in patients with sulfite sensitivity. See Chapter 22 for information on interactions.

Beta Adrenergic Blocking Drugs

The p-adrenergic blocking drugs are contraindicated in patients with bronchial asthma, obstructive pulmonary disease, sinus bradycardia, heart block, cardiac failure, or cardiogenic shock and in patients with hypersensitivity to the drug or any components of the drug. These drugs are Pregnancy Category C and are used cautiously during pregnancy and lactation and in patients with cardiovascular disease, diabetes (may mask the symptoms of hypoglycemia), and hyperthyroidism (may mask symptoms of hyperthyroidism). The patient taking p-adrener-gic blocking drugs for ophthalmic reasons may experience increased or additive effects when the drugs are administered with the oral beta blockers. Co-administration of timolol maleate and calcium antagonists may cause hypotension, left ventricular failure, and condition disturbances within the heart. There is a potential additive hypotensive effect when the beta-blocking ophthalmic drugs are administered with the phenothiazines.

Preadministration Assessment

Because the bronchodilators or antiasthma drugs may be given for asthma, emphysema, or chronic bronchitis, the preadministration assessment of the patient requires careful observation and documentation. The nurse takes the blood pressure, pulse, and respiratory rate before therapy with a bronchodilator or antiasthma drug is initiated. Respiratory rates below 12 min or above 24 min are considered abnormal. It is important to assess the lung fields and carefully document the sounds heard before therapy is begun. The nurse notes any dyspnea, cough, wheezing (a musical sound of the respiratory tract caused by air passing through a narrowed bronchial tube), noisy respirations, or use of accessory muscles when breathing. If the patient is raising sputum, the nurse records a description of the sputum. The nurse notes and records the patient's general physical condition. It is important to record any signs of hypoxia (eg, mental confusion, restlessness, anxiety, and cyanosis bluish...

Infant characteristics

Renal excretion is also immature early in life and a drug that depends on renal excretion, such as caffeine, theophylline, and some antibiotics, will accumulate in the infant in the first weeks and months of life but will gradually be better tolerated as the infant excretes it more effectively. These same drugs when given to an infant directly are given less frequently (daily instead of twice daily) in the first week of life.

Poisoning cases and toxic and fatal concentrations

Case 2 14 an 18-year-old female ingested 20-30 of extended-release tablets of theophylline (Theodur ) at about 1 30 a.m. From about 3 00 a.m., vomiting was started at 5 45 a.m., she visited an emergency room of a hospital and was admitted. Until 3 00 p.m., she suffered from vomiting in the vomitus, the debris of the tablets were included. At about 4 00 p.m., she complained of a bad headache her heart beat rate was 120 min, and blood theophylline concentration was 66.6 p,g mL. At 4 30 p.m., gastrolavage was performed by inserting a gastric tube. Then, 60 g of activated charcoal, 250 mL of magnesium citrate solution and 500 mL saline solution were orally administered slowly. At the same time, an intravenous drip infusion of 2 ampoules of Primperan (metoclopramide) and 25 mg of Wintermin (chlorpromazine) were made to prevent her from vomiting. Thereafter, she showed a trend of recovery the blood theophylline concentration in the next morning was as low as 6.1 p,g mL. Blood therapeutic...

See also Monoclonal antibodies General Information

Omalizumab (formerly rhuMab-E25) is a humanized monoclonal antibody against IgE, which blocks the interaction of IgE with mast cells. Several phase I and phase II trials have demonstrated its efficacy in patients with allergic asthma (1-4). In another placebo-controlled trial in 525 patients with severe asthma, the adverse effects profiles were similar in the treatment and placebo groups (8).

Organs and Systems Skin

Years with moderate to severe allergic asthma requiring inhaled glucocorticoids in a randomized, placebo-controlled, double-blind trial (11). There were no serious treatment-related adverse events, and the frequencies of most adverse events were similar with omalizumab and placebo. However, urticaria was more frequent with omalizumab (4 versus 0.9 ). It usually resolved spontaneously or with antihistamine therapy and did not recur with subsequent treatment. Urticaria was also reported in a small number of adults (0.5 ) given omalizumab for allergic rhinitis (12).

Other features of the patient

In patients with reduced respiratory reserve, such as those with emphysema, severe obesity, cor pulmonale, and kyphoscoliosis, opioids must be used with caution. The relative benefits and harms of using opioids in patients taking monoamine oxidase inhibitors, those with a history of drug abuse, asthma, hepatic impairment, hypotension, raised intracranial pressure, or head injury, and during pregnancy or breast feeding, should be carefully considered. Dextropropoxyphene, pethidine, and methadone should be used with caution (SEDA-21, 85).

Susceptibility Factors

Patients with underlying bronchial asthma and pheochro-mocytoma are thought to be particularly at risk of acute histamine release due to polygeline. A 45-year-old woman, who had used salbutamol and budesonide inhalers and oral theophylline for asthma and who had developed bronchospasm during induction of general anesthesia 6 weeks before, was readmitted for surgery under spinal anesthesia (8). During the procedure she developed two episodes of hypotension, which was corrected with fluids and intravenous mephentermine 6 mg. When blood loss reached 750 ml she was given an infusion of polygeline 3.5 , and 10 minutes later complained of respiratory difficulty and developed severe respiratory distress. Polygeline was withdrawn and she was given 100 oxygen with halothane by face mask. The oxygen saturation fell by more than 80 and she developed severe bradycardia and ventricular fibrillation. She was resuscitated.

Thiazides and Related Diuretics

The thiazide diuretics are contraindicated in patients with known hypersensitivity to the thiazides or related diuretics, electrolyte imbalances, renal decompensation, hepatic coma, or anuria. A cross-sensitivity reaction may occur with the thiazides and sulfonamides. Some of the thiazide diuretics contain tartrazine, which may cause allergic-type reactions or bronchial asthma in individuals sensitive to tartrazine.

See also Neuromuscular blocking drugs General Information

Rapacuronium, an aminosteroid non-depolarizing neu-romuscular blocking agent with a rapid onset and a comparatively short duration of action (1,2), was withdrawn from the US market in March 2001 and subsequently worldwide. The manufacturers informed the FDA in an open letter about postmarketing reports of severe bronchospasm and some deaths of unknown origin associated with rapacuronium. The severity of the incidents recently reported to the manufacturers was impressive enough to cause fears about patient safety. This event highlights the need for continued surveillance, not only during clinical trials but also during the routine use of approved drugs.

Drug Administration Drug formulations

Adverse effects are generally more likely when salbutamol is given by injection. At therapeutic doses, the pressurized aerosol and dry powder inhalers produce equivalent bronchodilatation without significant adverse effects (SEDA-22, 191). Patients with severe asthma tolerate large doses of nebulized salbutamol. In severe asthma there is a reduction in early lung absorption of salbutamol after inhalation, which does not occur in mild asthma. This results in lower plasma concentrations of salbutamol and less tremor (SEDA-22, 191). This is consistent with the findings in 323 patients who attended emergency departments because of severe asthma. Initial treatment with nebulized salbutamol 7.5-10 mg or up to 3.5 mg by pressurized aerosol in 1 hour caused no serious adverse effects. Tremor was noted in about 15 of the patients. About one-third of these patients failed to achieve an adequate therapeutic response to salbutamol. The most serious adverse effect of highdose salbutamol would be...

Tacrine tetrahydroaminoacridine and hexafluorenium

Tacrine (tetrahydroaminoacridine) and hexafluorenium, used sometimes to potentiate and prolong the action of suxamethonium (333,334), inhibit plasma cholinesterase. Hexafluorenium also inhibits acetylcholinesterase and has a weak neuromuscular blocking action of the non-depolarizing type a phase II block develops fairly rapidly when repeated injections of even small doses (0.2-0.3 mg kg) of suxamethonium are given in combination with hexafluorenium (335). Fasciculation is reportedly reduced and hyperkalemia prevented (336), as is the increase in intraocular pressure (337), when hexafluorenium is given before suxamethonium. Because of a lack of consistency of successful results from various investigators, this method is not recommended for patients who are especially at risk from hyperkalemia or increased intraocular pressure. Simultaneous injection of hexafluorenium and suxa-methonium can cause severe bronchospasm.

Pharmaceutical interest

Uses In China, the juice expressed from the leaves of Eclipta prostrata (L.) L. is used to keep the hair black and to stimulate its growth. The pounded plant is used to check bleeding, to heal wounds and burn, and to soothe contusion. A decoction of the plant is used to check bleeding and to invigorate health. In India, Eclipta prostrata (L.) L. is used to invigorate health and to assuage hepatic and spleen discomfort. In Malaysia, the plant is used to promote recovery from childbirth. In the Philippines, the plant is used to assuage liver discomfort. In Vietnam, Eclipta prostrata (L.) L. is used to treat mycosis, assuage lung discomfort, treat asthma, bronchitis and to invigorate breathing.

Second Generation Effects Pregnancy

In pregnant women with a history of migraine or vascular headache the use of terbutaline (and its congeners) should be avoided because of the risk of cerebral ischemia (SEDA-8, 145). One pregnant woman with asthma suffered a hypotensive episode after treatment with subcutaneous terbutaline (SEDA-12, 123).

Drug Drug Interactions General

Both positive and negative drug interactions have been reported with theophylline. The usefulness of combination products has also been discussed (SEDA-6, 2) (SEDA-11, 7). The use of combinations complicates the evaluation of adverse effects, particularly those of theo-phylline and ephedrine. The likelihood of adverse effects of each component and synergistic effects between components must be evaluated in relation to the patient's clinical condition. A positive feature is the likelihood of greater compliance with an effective combination product. In one study, antacids increase the rate of theophylline absorption without a change in total systemic availability The concomitant use of drugs that reduce theophylline clearance can produce toxic serum concentrations with therapeutic doses of theophylline. Most of these drugs are believed to have this effect by inhibiting the hepatic microsomal P450-metabolizing enzymes that are responsible for the biotransformation of theophylline. Such...

Food Drug Interactions

Food can affect both the absorption and the clearance of theophylline. One study showed that the absorption of a modified-release formulation of theophylline was very slow after an overnight fast, in contrast to absorption after a test meal (86). The effect may be dose-related. More specifically, dietary protein significantly affects theophylline clearance a low-protein diet reduces theo-phylline clearance and a high-protein diet increases it. The implications for clinical practice have not been elaborated, but dietary extremes are contraindicated in patients taking theophylline (51).

Family Commelinaceae R Brown 1810 nom conserv the Spiderwort Family

Pharmaceutical interest An example of medicinal Commelinaceae is Mur-dannia edulis (musli siyah), used by Asian residing in Britain to invigorate health, regulate urination and to treat asthma and colic. A number of plants classified within the family Commelinaceae have been investigated for their therapeutic potential. Rhoeo spathacea (oyster plan) contains dopamine and could be of potential value in combating Parkinsonism. There is an expanding body of evidence to suggest that a-glucosidase inhibitors isolated from Commelinaceae prove positive in the treatment of diabetes. Approximately 20 species of Commelinaceae are medicinal in the Asia-pacific. Note that many of these plants are used to heal and soothe injured skin.

See also Individual agents General Information

In some highly developed countries that have had great success in reducing dangerous infectious diseases through immunization, there are controversial discussions regarding the benefits to harm balance of immunization. Because the incidence of vaccine-preventable diseases is reduced by increasing coverage with an efficacious vaccine, adverse events, both those caused by vaccines themselves (that is true adverse reactions) and those associated with immunization only by coincidence or as a result of faulty routines, become increasingly frequent. Not surprisingly, vaccine safety concerns have become increasingly prominent in successful immunization programs. Chronic illnesses recently claimed to be linked with immunizations include asthma, autism, diabetes, and multiple sclerosis. Given the current increasingly antivaccine'' environment that has developed in some countries, it is hard to imagine that the full potential of new vaccines will be harnessed. To avoid damage to current

General risks of multiple immunizations

The Safety Review Committee of the IOM has reviewed the evidence regarding multiple immunizations and immune dysfunction (60). The review did not support the hypothesis that an infant's immune system is inherently incapable of handling the number of antigens to which children in the USA are exposed during routine immunizations. The committee rejected a causal relation between multiple immunizations and increased risks of infections or type 1 diabetes mellitus. The evidence was inadequate to accept or reject a causal relation between multiple immunizations and allergic disease, particularly asthma.

Epidemiological Data

Some authors 64 explored the use of herbs in children with attention-deficit-hyperactivity disorder or depression the prevalence of herbal therapy among 117 patients was 20 and, interestingly, the children's psychiatrists and paediatricians were not aware of such use. Ginkgo biloba, Echinacea and St John's wort were the herbs most frequently given. A survey performed in three paediatric gastroenterological centres reported that 14 of 208 children with inflammatory bowel disease used herbal medicines to treat this condition, in addition to conventional therapies 65 . In Australia, 29 of 174 asthmatic children on therapy with bronchodilators and disodium cromoglycate or inhaled steroids had used herbal preparations to ease their symptoms 66 .

Miotic Direct Acting

These drugs are contraindicated in patients with hyper-sensitivity to the drug or any component of the drug and in conditions where constriction is undesirable (eg, iritis, uveitis, and acute inflammatory disease of the anterior chamber). The drugs are used cautiously in patients with corneal abrasion, pregnancy (Pregnancy Category C), lactation, cardiac failure, bronchial asthma, peptic ulcer, hyperthyroidism, gastrointestinal spasm, urinary tract infection, Parkinson's disease, recent myocardial infarction, hypotension, or hypertension. These drugs are also used cautiously in patients with angle closure glaucoma because miotics can, occasionally, precipitate angle closure glaucoma by increasing the resistance to aqueous flow from posterior to anterior chamber. See Chapter 24 for information on interactions.

Q How Does Marijuana Affect Your Health

Smoking anything is not healthy, but marijuana is less dangerous than tobacco and people smoke less of it at a time. This health risk can be avoided by eating the plant instead of smoking it 13 , or can be reduced by smoking smaller amounts of stronger marijuana. There is no proof that marijuana causes serious health or sexual problems 14 but, like alcohol, its use by children or adolescents is discouraged. Cannabis is a medicinal herb that has hundreds of proven, valuable theraputic uses - from stress reduction to glaucoma to asthma to cancer therapy, etc. 15 .

Drug Interactions with Piperine Major Constituent of Black Pepper

Administration of piperine significantly increased plasma rifampicin concentrations in patients with pulmonary tuberculosis (141). Rifampicin is a substrate of P-glycoprotein, and inhibition of P-glycoprotein by piperrine is a possible mechanism. In a study involving six human subjects, piperine (20 mg daily dose) increased both maximum serum concentration and AUC of propranolol. Comparable effects were also observed with theophylline (142). Velpandian et al. reported increased AUC of phenytoin in rats in the presence of piperine. Similar effect was also observed when phenytoin was administered in rats intravenously indicating that piperine also blocked metabolism of phenytoin. Similar effect was also observed with human subjects (143). In another study, 20 mg dose of piperine increased AUC and maximum plasma concentrations of phenytoin compared to controls. The elimination rate constant was also affected (144).

Chemical Abstracts Service Registry Number 8007930 Formal Names Atropa belladonna

Belladonna substances can ease premenstrual syndrome. They can reduce spasms in smooth muscles of the digestive tract, but they cause tremors or stiffness in other muscles. Heart rate is accelerated. Migraine headaches can lessen. An experiment showed that belladonna can reduce breathing abnormalities in infants. Some medical traditions have used belladonna for reducing sweat and other secretions and against tonsilitis, meningitis, scarlet fever, whooping cough, and epilepsy. At one time medical practitioners gave belladonna to fight Parkinson's disease and drug addiction, but those treatments have been superseded by others. Belladonna preparations have modern usage against vesico-ureteral reflux, a condition in which urine flows back toward the kidney from the bladder. Caregivers have administered belladonna to treat various pains, ranging from kidney stones to sore throat. Belladonna powders and cigarettes have been used against asthma.

Poisoning cases blood concentrations and fatal doses

Case 1 12 a 49-year-old female died during admission to a hospital for treatments of bone fracture of the right leg inflicted by a traffic accident. She had a past history of bronchial asthma. It was estimated that she had died of asthmatic attack due to ketoprofen shock. The concentration of ketoprofen in blood sampled at autopsy was 160 ng mL, and that in the liver was 10 ng g.

Pregnancy Category X

Nandrolone is used to treat breast cancer and anemia, and the drug has improved asthma and Sjogren's syndrome, a disease that destroys salivary, sweat, and tear glands. Healing action on cornea afflictions has been observed, and rat experiments have explored nandrolone's potential for speeding recovery from tooth extractions. A skin cream containing nandrolone is used against eczema. Human research indicates that the drug can improve osteoporosis, a disease causing brittle bones, although results conflict on how long the improvement lasts. Among some diabetics with a kidney condition called Kimmelstiel-Wilson syndrome, nandrolone has helped both renal and eyesight difficulties. In kidney dialysis, patients' experimental use of nandrolone was able to improve weariness, increase muscle mass, and fight malnutrition. The compound has helped AIDS (acquired immunodeficiency syndrome) patients build up weight, muscles, and strength. The substance has also been given in hopes of...

Coleus scutellarioides L Benth

Cardiovascular properties Coleus species have attracted a great deal of interest due to forskoline (or coleonol) characterized from Coleus forskohlii (Willd.) Brig. Forskoline is a diterpene that shows encouraging signs in the treatment of hypertension, heart failure and asthma. The precise mechanism of the action of this diterpene is based on its ability to boost the enzymatic activity of activated adenylate cyclase, hence increasing the intracellular cyclic adenosine monophosphate (AMPc) (Marone G et al., 1987 Tsukawaki M et al, 1987).

Recent Advances in Nebulizer Technology

Conventional Jet Nebulizer

Nebulizers have been used for asthma therapy for many years and are used for the delivery of fine droplets of drugs to the lungs. For this reason they have been optimized for aerosol delivery in the upper range of inhalation Adaptive aerosol delivery technology (150) is an approach developed to address the highly variable drug delivery characteristic of conventional delivery systems. These novel types of nebulizers adapt to the individual breathing pattern of the patient (determining the shapes of the inspiratory and expiratory flow pattern) and deliver the aerosol only during inhalation. Such systems pulses aerosol delivery only during inhalation and each pulse is matched to the previously determined inspiration time. The breathing pattern is continuously monitored and the system adapts to the changes in pattern. Furthermore, such systems are programmed to deliver a preset metered dose. An example of this new technology can be found in the HaloLite AAD system (Profile Therapeutics,...

Physiological Actions of Prostanoids

DP receptor localization also seems to vary considerably between species. For example, platelet DP receptors seem to be most abundant in humans and not in other animal species (57). PGD, is also the major prostaglandin produced by mast cells following immunological challenge (58). Recent studies using mice deficient in the DP receptor have suggested that PGD, production may be important in some aspects of asthma (59). In a model of asthma, when challenged with ovalbumin, DP_ _ mice showed reduced lymphocyte accumulation in the lung compared with wild-type controls, and in addition, failed to develop airway hyperreactivity. These data suggest that, in mice at least, DP receptors may play a role in airway hyperreactivity.

Inhibition of Mediator Release

The discussion so far may have given the impression that allergic, particularly asthmatic, attacks (responses) are solely mediated by a sudden release of copious quantities of histamine that are stimulated to do so by some pathological event such as an autoimmune reaction, pollen exposure, or an antigen-antibody reaction. While it is true that histamine is released by mast cells (and also their circulating counterparts, the basophils), causing swelling of nasal passages (by affecting blood vessels), itching (by exciting nerve endings), and precipitating rhinorrhea (by causing mucous glands to release their contents), these tend to be short-lived events. Long-acting inflammatory mediators are also known to exist. One, which was long believed to cause the characteristic bronchospasms of an asthma attack named slow-reacting substance anaphylaxis (SRS-A), was suspected already in the 1920s, but it was not referred to in the literature until 1930. Its nonidentity with histamine was shown...

Hyperthyroidism and thyrostatics

The corticosteroids arc grouped according to their capacity for Na+ retention, their effects on carbohydrate metabolism, and their anti-inflammatory effects. Thus, glucocorticoids have pleoiotropic effects and arc used in clinical practice in (as well as replacement therapy in cases of adrenal insufficiency) treating diverse diseases such as inflammatory rheumatic disorders, asthma, autoimmune diseases (systemic lupus erythematosus and others), acute kidney transplant rejection, and allergic and skin diseases. In pregnant women at risk for preterm birth, corticosteroids are also used for the induction of lung maturity. High doses of daily glucocorticoids are usually required in patients with severe diseases involving major organs, whereas alternate-day regimens may be used in patients with less aggressive disease. Intravenous glucocorticoids (pulse therapy) are frequently used to initiate therapy in patients with rapidly progressive, inmunologically mediated diseases (Rournpas 1993)....

The Toxicology Examination

Occasionally, mere detection of a drug is sufficient. But, in the case of some prescription medications, the actual amount present must be quantified. A request for therapeutic drug analysis may be made even if the autopsy has already determined the cause of death. If a history of seizure is obtained, the pathologist may request an antiepileptic drug screen to determine whether or not the person was taking any such medication. The same holds true for, e.g., theophylline in individuals with asthma. An individual who has committed suicide may have been prescribed therapeutic drugs for depression or other mental illness. A test for these drugs may indicate the degree of patient compliance. In forensic toxicology, a negative laboratory result carries the same weight as a positive result. Often the nature of a suspected toxin is unknown. This type of case is termed a general unknown. 41,42 In cases of this nature, a full analysis of all available specimens by as many techniques as possible...

Issues of Special Interest in Oral Fluid Testing

There are a number of products available on the Internet that guarantee to beat oral fluid drug of abuse tests. There is no scientific evidence that these products work. Using an on-site oral fluid drug screen, Oratect, Wong et al. (79) investigated the effects of various adulterants and foodstuffs. Common foods, beverages, food ingredients, cosmetics and hygienic products were demonstrated not to cause false-positive results when tested 30 min after their consumption. In addition, two commercial adulterant products Clear Choice Fizzy Flush and Kleen Mouthwash were tested and had no effect in destroying the drug compounds or changing the pH of the oral fluid. Their effect was through washing oral cavity and not different from a common mouthwash. In another study, a series of potential adulterants of oral fluid were evaluated and shown not to interfere in Cozart microplate EIA for opiates (80).

Ephedrine And Pseudoephedrine

Ephedrine Drum Factories Vietnam

Ephedrine and pseudoephedrine are often used legally to alleviate congestion. When irritated, the tissues lining the inside of the nose and the respiratory system become swelled, which causes congestion. Ephedrine and pseudoephedrine cause the blood vessels to shrink, which brings down the swelling and allows easier breathing. Pseudoephedrine is used primarily in cold and allergy medications. Ephedrine is used more often in asthma medications as a bronchodilator. By acting on the blood vessels in the lungs, ephedrine helps ease breathing by relaxing and widening air passages.7
