Agonist, Nicotinic

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.
