Description
Description
Tropicamide, a miotic agent, primarily acts by antagonizing the muscarinic acetylcholine receptors, specifically the M3 subtype, located in the iris sphincter muscle and the ciliary muscle. By blocking these receptors, tropicamide inhibits the contraction of the iris sphincter muscle, leading to mydriasis (pupil dilation). This mechanism is crucial in ophthalmology for dilating the pupil, which is essential for various eye examinations and procedures. The selective action on the iris sphincter muscle is attributed to its higher sensitivity to anticholinergic agents compared to the iris dilator muscle.
