B.Pharmacy Physical Pharmaceutics II
Explore the physical and physicochemical principles that govern pharmaceutical formulations, with emphasis on colloidal systems, rheology, suspensions, emulsions, micromeritics, and drug stability.
Build a strong understanding of how the physical and physicochemical properties of drugs and excipients influence pharmaceutical dosage forms. The subject connects fundamental principles with formulation development, product evaluation, stability testing, and determination of expiry dates.
