Mechanism of action - Wikipedia, the free encyclopedia

In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its.

Common examples of drugs that utilize this method are antacids and laxatives. 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. Drugs that do not bind to receptors produce their corresponding therapeutic effect by simply interacting with chemical or physical properties in the body. In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect.

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.

The mechanism of action of a medication is the specific biological process through which the medication causes the reduction in symptoms. The mechanism of action of a psychosocial intervention (for example, psychotherapy) is the specific intervention that produces change in the client's symptoms.

(I.e., we do not know what specific therapeutic interventions produce the change when someone's symptoms are improved in psychotherapy.). For many medications, particularly psychotropic medications, the specific mechanism of action is unknown. Similarly, the mechanism of action for most psychosocial interventions is unknown.
