Pharmacology of Antiprotozoal Drugs: Amebiasis and Malaria

This comprehensive topic is critical for Zambian university students in pharmacology, medicine, and public health, focusing on two major protozoal diseases. For amebiasis, it covers the classification of drugs into luminal, systemic, and mixed amebicides, with detailed study of Metronidazole (mechanism, pharmacokinetics, adverse effects) and adjuncts like Paromomycin and Chloroquine. For malaria, it provides an exhaustive review of antimalarial drug classification: causal prophylactics, blood schizonticides, and gametocidal agents. The chemical classes, mechanisms of action, and clinical use of drugs like Chloroquine, Quinine, Artemisinin derivatives, and Mefloquine are examined in depth. Given the high burden of malaria in Zambia, this knowledge is not only academically essential for passing rigorous tertiary exams but also forms the practical foundation for effective diagnosis, treatment, and chemoprophylaxis strategies in clinical and community health practice.
