Vapor pressure and volatility

Vapor Pressure And Volatility

In general, absorption of inhaled drug is dependent upon the physical characteristics of the drug, including particle size, lipid solubility, and volatility. Clearly, a drug's volatility would play an important role in determining its inhalation potential. Drug volatility is determined by many factors, including boiling point, melting point, and vapor pressure. Since many abused substances are less volatile than organic solvents and are smoked would be negligible. On the other hand, vapor...
