Chemical interactions between the drug molecules and the solvent. physical pharmaceutics by ramasamy c and manavalan r pdf
Pharmaceutical formulation is not merely about mixing active ingredients with excipients. It requires a profound understanding of how molecules behave under various conditions. Physical pharmaceutics examines the physical and chemical properties of drug molecules before they are formulated into a final dosage form.
