Basic Pharmacokinetics and Pharmacodynamics

PHAR69921 Basic Pharmacokinetics and Pharmacodynamics 15 Full year Postgraduate Taught Level 6 Leon Aarons Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Masters/Integrated Masters P4 ' European Credit Transfer & Accumulation System Rating : 7.5 This introductory unit is designed to give the student an understanding of fundamental concepts in pharmacokinetics and pharmacodynamics, essentially how drugs get into the body, how they get around the body and how they get out of the body. Topics include the processes of absorption, distribution, metabolism and excretion (ADME), the concept of compartmental analysis, and pharmacokinetic-pharmacodynamic concepts. Emphasis is given to explaining how chemical properties of drug interact with physiological aspects of the human body to affect the behaviour of different drugs and the variation between individual patients. Quantitative assessment of the processes (modelling and data analysis) is described with reference to drug discovery, drug development and therapeutic usage. The module also provides experience in solving numerical problems relating the time-course of drugs and their metabolites in the body. This unit is essential for subsequent units which focus on physiologically-based models and advanced approaches to data analysis in pharmacokinetics and pharmacodynamics. Theoretical knowledge will be disseminated in lectures and tutored workshops. Students will then work on a series of structured assignments that emphasise the application of theory by solving problems.
