Pharmacology is a branch of medicine, biology and pharmaceutical sciences concerned with drug or medication action, where a drug may be defined as any artificial, natural, or endogenous molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism.
Pharmacology is the study of how a medicine works, how the body responds to it, and the changes that occur over time. The two main areas of pharmacology are: pharmacokinetics and pharmacodynamics.
Pharmacology is the study of interaction of drugs with living organisms.
It also includes history, source, physicochemical properties, dosage forms, methods of administration, absorption, distribution mechanism of action, biotransformation, excretion, clinical uses and adverse effects of drugs.
