This course teaches the scientific background and technical aspects which are important in the development of basic dosage forms. This course will focus on physicochemical foundation of various dosage forms and drug delivery system. Discussion will include various preformulation factors like rheology, viscosity and elasticity. Some basic physicochemical processes which have extensive application in the development of basic dosage forms will also be discussed. All these preformulation aspects helps pharmacist to make rational decisions on scientific basis concerning the art and technology of pharmaceutical products.
