What is Timolol?
Timolol is a non-selective beta-adrenergic antagonist used to reduce intraocular pressure in eye drop solutions and to treat hypertension in tablet form. Approved by the FDA in 1978, Timolol effectively manages conditions such as open-angle glaucoma and hypertension. By blocking the action of the sympathetic nervous system, Timolol decreases intraocular pressure and affects heart function.
Timolol Uses
- Eye Pressure Reduction: Used to treat high pressure inside the eye due to glaucoma or other eye diseases (open-angle type) such as ocular hypertension. Lowering high pressure inside the eye helps to prevent blindness.
- Hypertension Treatment: Administered in tablet form to treat high blood pressure.
How Timolol Works
Timolol belongs to a class of medications known as beta-blockers. It works by reducing the amount of fluid inside the eye, thereby decreasing intraocular pressure. It also blocks the action of the sympathetic nervous system, affecting heart function.
