Pharmacology of Psychotropic and CNS Drugs

This topic provides an in-depth exploration of the pharmacology of drugs acting on the central nervous system, tailored for diploma and degree students in Zambian medical and pharmaceutical programs. It encompasses the mechanisms of action, therapeutic uses, and adverse effects of major drug classes, including antipsychotics (typical and atypical), antidepressants (TCAs, SSRIs, MAOIs), mood stabilizers (lithium, valproate), and drugs used in dementia (cholinesterase inhibitors, memantine). The module also covers the pharmacology of general and local anaesthetics, as well as the clinical management of substance abuse disorders involving opioids, cannabis, cocaine, and ethanol. For tertiary learners, this knowledge is vital for rational pharmacotherapy in psychiatry, neurology, and anaesthesiology. The content is designed to meet the rigorous syllabus requirements of Zambian universities and colleges, linking pharmacological principles to Zambian clinical contexts. Understanding these drugs prepares students for prescribing decisions, managing side effects, and answering complex pharmacology questions in professional examinations.
