Istalol is a prescription medicine used for reducing eye pressure in people with chronic open angle glaucoma or high eye pressure (ocular hypertension). This medication works to lower eye pressure by decreasing the amount of fluid produced by the eye. The drug comes in the form of an eye drop and is specifically formulated for once-daily use.
What Is Istalol?Istalol® (timolol maleate) is a prescription eye drop approved to lower eye pressure in people with chronic open angle glaucoma or high eye pressure (ocular hypertension). It is different from other timolol eye medications because it is a unique formulation that is better absorbed into the eye, allowing for once-daily dosing.
Who Makes This Medication?Istalol is made by Bausch & Lomb Pharmaceuticals, Inc., and is marketed and distributed by ISTA Pharmaceuticals, Inc.
How Does It Work?Istalol belongs to a group of drugs called beta-adrenergic blocking agents, more often known as beta blockers. As the name implies, these medications block beta receptors in the body. Beta receptors are located in a number of places within the body, including the eyes. Beta blockers lower the pressure in the eye by decreasing the amount of fluid produced by the eye (known as aqueous humor).
