Phenylephrine + Tropicamide is primarily used in ophthalmology for diagnostic procedures and short-term therapeutic purposes. It belongs to the group of ophthalmic diagnostic agents.
It is indicated for dilating the pupil (mydriasis) for diagnostic eye examinations, inducing short-acting mydriasis in pre-and post-operative states, and relaxing the ciliary muscle (cycloplegia) for diagnostic procedures.

Phenylephrine + Tropicamide is a combination medicine used in ophthalmic applications.
Phenylephrine is a decongestant that works by reducing swelling of blood vessels. This substance affects the α1-adrenergic receptor in the eye, causing the dilator muscle of the pupil to contract and thus widen or dilate the pupil (mydriasis).
Tropicamide is an anticholinergic agent that blocks acetylcholine, a neurotransmitter, at muscarinic receptors in the eye. It relaxes the sphincter muscle of the iris and the ciliary muscle, also contributing to the dilation of the pupil and temporary paralysis of the ciliary muscle (cycloplegia).
