Antiprotozoal drugs by UNZA School of Health Sciences - 3rd Year Pharmacology and Toxicology

Description

These detailed tertiary-level notes on Antiprotozoal drugs are designed for third-year Pharmacology and Toxicology students within the Biomedical Sciences programme at the University of Zambia (UNZA) School of Health Sciences. The document begins by outlining the challenge of treating protozoal infections, which are eukaryotes with metabolic processes closer to humans. It provides a comprehensive summary of anti-protozoal agents used against major diseases like Amebiasis, Malaria, Trypanosomiasis, Leishmaniasis, Toxoplasmosis, and Giardiasis, listing specific drugs and their brand names. A significant focus is placed on Amebiasis, detailing the life cycle of Entamoeba histolytica, complications, and the classification of drugs into luminal, systemic, and mixed amebicides. The mechanism of action, pharmacokinetics, and adverse effects of key drugs like Metronidazole and Tinidazole are thoroughly explained. The second major section covers Malaria, describing the Plasmodium species, the parasite's life cycle, and a dual therapeutic and chemical classification of antimalarial drugs. It explains the mechanisms of various drug classes, including 4-aminoquinolines (e.g., Chloroquine), biguanides, cinchona alkaloids, and sesquiterpene lactones (e.g., Artemisinin), alongside their specific adverse effects. This resource serves as essential revision material for university students, providing a systematic and authoritative overview of chemotherapy for protozoal diseases to aid in examination preparation and academic mastery.
