Backgrounds
Approved drugs include approximately 35% bases, 20% acids, 30% ampholytes and 15% neutrals. The properties of ionisable compounds are highly influenced by the pH of the environment. The pH range in gastrointestinal tract is from ~2 to ~9. Commonly absorption related properties, permeability and solubility, for drug candidates is.. The access to the whole abstract and if available the presentation file is available to FIP members and to congress participants of that specific congress.
