Is a branch of the pharmaceutical sciences that deals with: investigations of physical and chemical properties of drug molecules design, fabrication and evaluation of drug delivery systems monitoring how drug products are absorbed, distributed, metabolized and excreted in the body

Deals w the physicochemical principles underlying the development of a successful dosage forms
