TIMOPTIC (timolol maleate)

Ophthalmology Approved 1978-08-17

Timoptic is an ophthalmic solution used for patients with high pressure inside the eye, specifically those with open-angle glaucoma or ocular hypertension. It helps manage these conditions by lowering intraocular pressure, which is a significant risk factor for optic nerve damage and vision loss. A single dose can maintain this pressure-lowering effect for up to 24 hours.

How TIMOPTIC Works

This medication works by blocking both beta 1 and beta 2 adrenergic receptors. While the exact process is not fully established, evidence suggests it lowers eye pressure primarily by reducing the formation of aqueous fluid within the eye.
