Tropicamide + Phenylephrine Hydrochloride
Indications
Tropicamide + Phenylephrine Hydrochloride is used for inflammatory conditions of the uveal tract. It may also be used to lower intraocular pressure for a short time in glaucoma. For diagnosis, doctors use it in retinal photography, in checking refractive errors, in fundus examination or photography, and in slit lamp examination. It is also used before surgery, when the procedure needs a clear view of the structures behind the iris, such as cataract extraction, vitrectomy and retinal detachment surgery.
⚠️ Always consult a registered physician before taking any medicine.
Pharmacology
Tropicamide binds to and blocks the muscarinic M4 receptors in the muscles of the eye. By blocking the response of the iris sphincter muscle and the ciliary muscles to cholinergic stimulation, it widens the pupil and paralyses the ciliary muscle.
Phenylephrine Hydrochloride is a selective alpha-1 agonist. It widens the pupil (mydriasis) without paralysing the ciliary muscle (cycloplegia). It also tends to reduce intraocular lesion through its vasoconstrictor action.
