What Is Timolol Used For?

How Does the Medication Work?

Timolol 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, including the eyes, heart, and blood vessels. Stress hormones such as adrenaline bind to these receptors and cause certain reactions in the body, such as:
 
By blocking beta receptors, timolol causes the reverse effect of stress hormones. It decreases heart rate and both systolic and diastolic blood pressure. It is not entirely clear how the medicine works to prevent migraines or to improve survival after a heart attack.
 
Timolol lowers the pressure in the eye by decreasing the amount of fluid it produces (known as aqueous humor).
