Pharmacology is the science of studying chemical compounds with a therapeutic effect, and the way drug compounds interact with living organisms to produce a therapeutic effect by binding to protein receptors or inhibiting certain enzymes within the body. Pharmacology is also concerned with the study of the structural properties of drugs, how drugs are designed and manufactured, molecular/cellular/organic pharmaceutical techniques, diagnostic drugs, drug incompatibility, toxicology, therapeutic properties, clinical applications and side effects of medicinal drugs.​
