Gastrointestinal Pharmacology

Gastrointestinal Pharmacology is a fundamental subject for Zambian tertiary students in medical, pharmacy, and nursing programs, focusing on the pharmacologic management of common GI disorders. The topic covers drugs used for peptic ulcer disease (PPIs, H2 antagonists, cytoprotectives), gastroesophageal reflux disease (GERD), nausea and vomiting (anti-emetics like ondansetron, metoclopramide), diarrhea (anti-motility agents, rehydration therapy), and constipation (laxatives). Students will learn about the physiology of acid secretion, the mechanisms of action of different drug classes, and their appropriate use in various clinical scenarios, including H. pylori eradication therapy. For students in Zambian colleges and universities, understanding GI pharmacology is essential due to the high prevalence of GI conditions in the population. Mastery of this topic ensures competency in prescribing safe and effective treatments, a key requirement for passing professional examinations and for effective practice in both outpatient and inpatient settings.
