agonist agÂ·oÂ·nist (Äg'É-nÄ­st) n. A contracting muscle that is resisted or counteracted by an antagonistic muscle. A substance that can combine with a cell receptor to produce a reaction typical for that substance.
Definition. An inverse agonist is a molecule that binds to the same site as an agonist and is considered to be a full agonist. However, it elicits the opposite effect to that of a normal agonist, i.e.: demonstrates negative efficacy.n antagonist reduces the effect of an agonist by preventing it from binding to receptors. Both antagonists and inverse agonists reduce the activity if a receptor and, in the presence of an agonist, reduce its activity.
