Pharmacology as a course involves the study of drugs and their effects on the human body. It explores how medications interact with biological systems, focusing on the mechanisms of drug action, therapeutic uses, side effects, and toxicology. Students learn about various drug classifications, the processes of drug absorption, distribution, metabolism, and excretion, as well as factors that influence drug response. The course integrates knowledge from disciplines such as physiology, biochemistry, and pathology to provide a comprehensive understanding of how drugs work. It also covers the principles of drug development, clinical trials, and the safe and effective use of medications in the treatment of diseases. Through theoretical and practical components, pharmacology prepares students for careers in medicine, pharmacy, nursing, and biomedical sciences, emphasizing critical thinking, clinical reasoning, and evidence-based practice.
