Pharmacology concerned with the study of drugs, used for treatment of animals and humans. It involves the application of drugs to various animal species and their reactions following such application. Pharmacology looks at the molecular structure of drugs, how the drugs work, safe drug dosages, side effects associated with drugs, the discovery of new drugs, new applications for existing medications, drug treatment protocols, and a variety of related topics. Staff in this thematic area participate in training of both undergraduate and postgraduate students. At undergraduate level, they teach pharmacology to Bachelor of Veterinary Medicine, BSc. Wildlife and BSc Biomedical Technology students. At postgraduate level, pharmacology is taught to students undertaking Master of Science and PhD in Pharmacology and Toxicology. The course is designed for Veterinary, Medical and other graduates involved in the protection and improvement of animals and human health and environment. The post-graduate program is intended to train graduates to conduct research, teach in academic institutions and also undertake other related duties in government service and private sector. Graduates are exposed to a broad study of drugs, analytical techniques, as well as recent advances in pharmacology.
