Tropicamide

Tropicamide is a short-acting antimuscarinic agent primarily used as a mydriatic and cycloplegic agent in ophthalmic examinations. It works by blocking the effects of acetylcholine on the cholinergic receptors in the iris and ciliary body, resulting in a temporary dilation of the pupil and relaxation of the ciliary muscle. This is particularly useful during eye exams, such as retinal exams or glaucoma screenings, where a clear view of the interior structures of the eye is necessary. Tropicamide is administered as eye drops and its effects typically last for 1 to 2 hours. As a medical substance, it is essential for healthcare professionals to monitor patients during and after its administration, to ensure their safety and comfort.
