Timolol is a drug used to treat high pressure inside the eye (intraocular pressure), due to glaucoma or diabetes ocular hypertension. Timolol is available as 0.25% and 0.5% eye drops.
Timolol is a drug beta blockers or beta blockers that work by reducing the production of fluid in the eyeball. With reduced production of this fluid, intraocular pressure will decrease so that eye damage or other complications can be prevented.
To treat glaucoma, timolol can be used alone or in combination with several other drugs.
