This module covers the mechanisms of action and uses of the major groups of drugs and important aspects of pharmacokinetics and drug toxicity. Students must have a sound knowledge of physiology and biochemistry. Teaching is through lectures and compulsory tutorials.

After taking this module you will be able to:

1.Describe the actions of many of the important groups of drugs used in medicine.

2. Cite experimental evidence to support ideas about the detailed mechanism of action of drugs at the molecular, cellular or tissue level.

3. Understand how drugs (and toxins) may be of use in elucidating physiological processes.

4.Understand how the time-course of drug action may depend on the processes of drug absorption, distribution, metabolism and excretion, and how changes in the concentrations of drugs in the body can be described quantitatively (pharmacokinetics).

5.Understand how the activity of a drug is related to its chemical structure and how structural changes can modify therapeutic efficacy or toxicity.

6.Consider the problems of designing, developing and conducting clinical trials of new drugs.
