Pharmacology is the study of drugs, their sources, chemical properties, biological effects, and therapeutic uses. As a course, pharmacology covers how drugs interact with the body (pharmacodynamics) and how the body processes drugs (pharmacokinetics). It also includes topics like drug classifications, mechanisms of action, side effects, drug metabolism, and the principles of drug therapy.

Pharmacology is typically taught in medical, pharmacy, nursing, and biomedical science programs. It involves both theoretical learning and practical applications, including lab work, case studies, and clinical correlations. The course is essential for healthcare professionals as it helps them understand drug interactions, dosages, and the safe and effective use of medications in treating diseases.
