COURSE OBJECTIVES

This course presents the basic concepts and principles of biopharmaceutics and pharmacokinetics. The necessary mathematical expressions needed to characterize the absorption, distribution, metabolism, and excretion of drugs will be discussed with respect to routes of administration. Parameters that influence pharmacokinetic and therapeutic outcomes of the most common drug regimens will be emphasized. In addition, this course highlights some recent models i.e. compartmental models, their mathematical backbone and their relation to logical conclusions of drug time course in the body.
