The Department of Veterinary Physiology and Pharmacology was created from the former Department of Veterinary Anatomy and Physiology in the 1976/77 session. In 1995, the Biochemistry unit was established and the name of the Department was changed to the Department of Veterinary Physiology, Biochemistry and Pharmacology.
The department runs courses in Physiology and Biochemistry for D.V.M I (200 Level) and DVM II (300 Level) students; Pharmacology and Toxicology to D.V.M II and III (400 Level) and Clinical Pharmacology for D.V.M V (600 Level) students. Together with the department of Veterinary Anatomy, this department also teaches basic Physiology and Anatomy courses to the Second Year Agricultural students. Postgraduate degree programmes in Physiology and Pharmacology leading to award of M.Sc., M.Phil, and Ph.D degrees started in 1982.
The first head of the department is Professor M. O Olowookorun, the pioneer academic staff of the department, who retired in 2006. In the course of thirty-eight years of existence of the department, nine academic staff and two Chief Technologists have resigned or retired from the service of the University making Professor R.O.A Arowolo the longest serving member of the department.
Research programmes in the department cover various aspects of haematology, gastroenterology, adaptation physiology, toxicology, oncology, biochemistry of nutrition and xenobiotics; chemotherapy, smooth muscle pharmacology, neuro-pharmacology and ethno-pharmacology.
