Phenylephrine Hydrochloride

Overview

Basic Info

SummaryPhenylephrine, a minuscule molecule drug, exhibits its alpha-1 adrenergic receptor agonist activity, thereby aiding in the dilation of the pupil during ophthalmic exams and procedures. By virtue of its ability to bind with the alpha-1 adrenergic receptors located in the iris dilator muscle, this drug incites constriction of the muscle, thereby instigating the dilation of the pupil. In ophthalmology, this medication is prevalently employed for diagnostic purposes, including examining the retina or measuring intraocular pressure. Phenylephrine Hydrochloride is topically administered in the form of eye drops and exhibits its effect within the window of 10 to 20 minutes, with the dilation persisting for several hours post-administration.
