Cholinergic Agonists
Medical Definition: | Drugs that bind to and activate cholinergic receptors. |
Guide Notes: | GEN or unspecified; prefer specifics; DF: CHOLINERGIC AGON or CHOLINERGIC AG |
Previously Indexed: | Acetylcholine/pharmacology (1967-1994) |
Muscarinic Agonists - Drugs that bind to and activate muscarinic cholinergic receptors (RECEPTORS, MUSCARINIC). Muscarinic agonists are most commonly used when it is desirable to increase smooth muscle tone, especially in the GI tract, urinary bladder and the eye. They may also be used to reduce heart rate. | |
Nicotinic Agonists - Drugs that bind to and activate nicotinic cholinergic receptors (RECEPTORS, NICOTINIC). Nicotinic agonists act at postganglionic nicotinic receptors, at neuroeffector junctions in the peripheral nervous system, and at nicotinic receptors in the central nervous system. Agents that function as neuromuscular depolarizing blocking agents are included here because they activate nicotinic receptors, although they are used clinically to block nicotinic transmission. |
