This course greatly extends the introduction to pharmacokinetics given in the core module Principles of Drug Action, with particular emphasis being given to new aspects of pharmacokinetics. Topics covered include methods used in drug development to investigate the pharmacokinetic characteristics of new chemical entities in the pre-clinical and clinical phase. The role of pharmacokinetics in drug selection is highlighted and emphasis is placed on critical appraisal of the pharmacokinetic literature. Other topics include investigating drug interactions and population pharmacokinetics as a tool to inform drug development and the clinical utility of medicines. Students electing to take this unit will also have a chance to pursue a short assignment in an area of interest to their work place related to the area of pharmacokinetics and pharmacdynamics.
