Pharmacology is the branch of science that deals with the study of drugs.

3) Drugs

In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being.

4) Pharmacokinetics

the branch of pharmacology concerned with the movement of drugs within the body.

5) Pharmacodynamics

the branch of pharmacology concerned with the effects of drugs and the mechanism of their action.

6) Toxicology

the scientific study of poisons

7) Chemotherapy

the treatment of an illness using chemical substances
