In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. Receptor sites have specific affinities for drugs based on the chemical structure of the drug, as well as the specific action that occurs there. A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor. Common examples of drugs that utilize this method are antacids and laxatives. Drugs that do not bind to receptors produce their corresponding therapeutic effect by simply interacting with chemical or physical properties in the body.

For example, phenytoin is used to treat symptoms of epileptic seizures, but the mechanism by which this is achieved is still unknown, despite the fact that the drug has been in use for many years. However, some drug mechanisms of action are still unknown. For example, the mechanism of action of aspirin involves irreversible inhibition of the enzyme cyclooxygenase, therefore suppressing the production of prostaglandins and thromboxanes, thereby reducing pain and inflammation.

Similarly, the mechanism of action for most psychosocial interventions is unknown.

For many medications, particularly psychotropic medications, the specific mechanism of action is unknown.
