What is betaxolol ophthalmic, and how does it work (mechanism of action)?
Betaxolol is a beta-adrenergic blocking agent that is used for the treatment of glaucoma. When taken by mouth, betaxolol and other beta-adrenergic blocking agents act mainly by blocking the action of the sympathetic (adrenergic) nervous system, for example, on the heart. In addition to its effect on the heart, betaxolol reduces the pressure within the eye (intraocular pressure). This effect is thought to be caused by reducing the production of the liquid (called the aqueous humor) within the anterior chamber of the eye although the precise mechanism of its effect is not known. The reduction in intraocular pressure reduces the risk of damage to the optic nerve and loss of vision in patients with elevated intraocular pressure due to glaucoma. Betaxolol was approved by the U.S. Food and Drug Administration for ocular use as a 0.5% solution (Betoptic) in 1985 and as a 0.25% solution (Betoptic S) in 1989.
