WebTropicamide is a muscarinic (cholinergic) antagonist with pharmacological activity similar to atropine. Being relatively weak and short acting (effects lasting about 6 hours), it is clinically useful in producing dilation of the pupils (mydriasis) to facilitate fundal examination and measurement of refractive errors Pollack et al (1981). WebDirect-Acting Cholinergic Agonists: Many drugs classified as direct-acting cholinergic agonists are primarily selective to the muscarinic receptors but are nonspecific because the muscarinic receptors are located in the smooth muscle of the GI and genitourinary tracts, glands, and heart. Metoclopramide hydrochloride (HCl) is a direct-acting ...

WebCholinergic receptors bind Ach: Ach binds to two classes of receptors— nicotinic and muscarinic named for the drugs that were used to identify and distinguish them. Nicotine binds only to the former while muscarine (a mushroom poison) binds only to the other. When Ach binds to a nicotinic receptor it produces an excitatory postsynaptic potential.
