Mechanism of action (for a drug/medicine) (MOA)

In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor. Simplified, MOA is a term used to describe how a drug/medicine produces an effect in the body.
