The Department of Veterinary of Pharmacology and Toxicology came into being in 2012 as a component of the Faculty of Veterinary Medicine. It started as the Department of Physiology based on a formal agreement between the Government of the Federal Republic of Nigeria and the United States Agency for International Development (USAID). The terms of agreement contracted the Kansas State University to establish a standard Veterinary School to produce qualified Veterinarians, develop programmes for postgraduate training and research in various fields of Veterinary Medicine, train qualified Nigerians to staff and administer the Faculty and advise on facilities and programmes for further growth in physical and academic fields. The Department of Veterinary Pharmacology and Toxicology became saddled with the responsibility of: a. Providing a scientific basis in some aspects of preclinical and clinical Veterinary Medicine to Undergraduate Veterinary Students. b. Assisting other Departments and Faculties in training both undergraduate and postgraduate students through teaching and project supervision. c. Assisting in identifying alternative drug sources through research on medicinal plants and other medicinal remedies, and involvement in clinical evaluation and reevaluation of new and existing drugs. d. Providing diagnostic services in Veterinary Pharmacology and Toxicology to the University Community, surrounding states and the country at large.
