This unit provides an introduction to the study of drugs: chemicals which affect living systems. It covers some general principles of how drugs act, the therapeutic consequences and mechanisms of adverse effects. The basic principles of drug disposition in the body, including pharmacokinetics (Absorption, Distribution, Metabolism and Excretion), as well as methods of measuring drug effects are also briefly outlined.

The major part of this unit consists of a detailed account of selected major classes of drugs, which include drugs affecting the autonomic nervous system, peripheral nerve transmission (local anaesthetics), renal and cardiovascular functions, blood, and gastrointestinal function. Emphasis is given to therapeutic applications.
