Mechanism of action 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.Receptor sites have specific affinities for drugs based on the chemical structure of the drug, as well as the specific action that occurs there.Drugs that do not bind to receptors produce their corresponding therapeutic effect by simply interacting with chemical or physical properties in the body.or 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.

- Involuntary action. An involuntary action is one which occurs without the conscious choice of an organism. A reaction in response to a stimulus that is mediated via the reflex arc is known in physiology as a reflex, but the word reflex is also used informally for those involuntary responses that originate in the brain. Involuntary actions are opposite of voluntary actions that occur because of choice.
