Minims Phenylephrine (Phenylephrine hydrochloride) is available as an over-the-counter and prescription medication. It is used to dilate the pupil (mydriasis) during eye examinations and specific ophthalmic procedures. It may also help reduce eye redness by constricting superficial blood vessels. Pupil dilation is necessary for a thorough examination of the retina and other internal structures of the eye, enabling eye care professionals to assess eye health properly. The active ingredient in Minims Phenylephrine is Phenylephrine hydrochloride. Phenylephrine hydrochloride belongs to a class of medications known as sympathomimetic agents. It works by stimulating alpha-adrenergic receptors in the eye, causing contraction of the iris dilator muscle and constriction of blood vessels, resulting in pupil dilation and reduced redness. When administered as eye drops, it acts locally with limited systemic absorption.
