ISOPTO ATROPINE (atropine sulfate)

Ophthalmology Approved 2016-12-01

Isopto Atropine is an ophthalmic solution used to dilate the pupil and temporarily paralyze the eye's focusing muscles. It helps patients who require these effects for eye examinations or specific ocular conditions. Additionally, it treats amblyopia by blurring the vision in a patient's healthy eye to encourage the use of the weaker eye.

How ISOPTO ATROPINE Works

This medication works by blocking acetylcholine from binding to muscarinic receptors in the eye. This action prevents the pupillary sphincter muscle from contracting, allowing the pupil to dilate, while also paralyzing the ciliary muscle to stop the eye from focusing on objects.
