The activity mediated by agonists are opposed by antagonists, which inhibit the biological response induced by an agonist. The level of agonist required to induce a desired biological response is referred to as potency.

Guanylate cyclase-C agonists are a class of medications used to treat constipation associated with irritable bowel syndrome (IBS) and chronic constipation of unknown cause ( idiopathic constipation) in adults. IBS causes stomach pain or cramps, bloating, and infrequent or difficult passage of stools.Guanylyl cyclase (also known as guanylate cyclase) is an enzyme that catalyzes the synthesis of cyclic guanosine 3′,5′-monophosphate (cGMP) from guanosine 5' triphosphate (GTP).
