About IOPIDINE 1%

What is this medication? Iopidine 1 percent is a prescription ophthalmic solution that contains the active ingredient apraclonidine. This medication belongs to a class of drugs known as alpha-adrenergic agonists. It is primarily used by eye care professionals to prevent or manage a sudden increase in intraocular pressure, which is the fluid pressure inside the eye. High pressure within the eye can be dangerous and may lead to damage of the optic nerve if not properly controlled during medical procedures. This specific concentration of the medication is typically administered in a clinical setting shortly before and after certain types of laser eye surgeries. These procedures include argon laser trabeculoplasty, laser iridotomy, and laser capsulotomy. By reducing the production of aqueous humor and improving its outflow, Iopidine 1 percent helps ensure that the patient eye pressure remains within a safe range during and immediately following these ophthalmic interventions.
