Pharmacology is a branch of medical sciences concerned with the origin, therapeutic use, effects, and side effects of drugs. A drug may be defined as any artificial, natural, or endogenous molecule which exerts a biochemical or physiological effect on the cell, tissue or organ of an organism. More specifically, it is the study of the interactions between living beings and chemicals that affect normal or abnormal biochemical functions in the body. The field encompasses drug composition and properties, synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, medical applications, and adverse effects related to drugs. The two main areas of pharmacology are pharmacodynamics and pharmacokinetics. In broad terms, pharmacodynamics discusses the chemical reactions with the biological receptors, and pharmacokinetics discusses the absorption, distribution, metabolism, and excretion (ADME) of drugs from the biological systems.

Pharmacology teaching comprises not only traditional lectures with interesting colorful presentations but also extended clinical scenario-based sessions and short group discussions. The understanding of the subject is further enhanced with online available video sharing and gaming tools, used for better learning of one of the most volatile subjects in medical education. Students are further guided to prepare posters, presentations, and journals for the practical performed in the lab. New researches regarding drugs are also shared with them to develop interest and to impart updated knowledge. Finally, by the end of the term, students are well prepared for their professional exam in the discipline of Pharmacology.
