Physicochemical and Biological Properties of Drugs
Controlled release formulations are designed to maintain therapeutic drug levels for an extended period. For successful formulation, the physicochemical and biological properties of the drug must meet specific criteria. I. Physicochemical Properties of Drugs 1. Aqueous Solubility: Drugs should have moderate solubility (not too high or too low). Relevance: Low solubility can limit the drug’s…
