How Does Betimol Work?

Betimol 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).
