Pharmacology (from Greek φάρμακον, pharmakon, "poison in classic Greek; drug in modern Greek"; and -λογία, "Study of" -logia) is the branch of medicine and biology concerned with the study of drug action.[1] More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties, interactions, toxicology, therapy, and medical applications and antipathogenic capabilities.
