Betaxolol is a drug to lower the pressure inside the eyeball due to ocular hypertension or glaucoma. Lowering the pressure inside the eye (intraocular) can reduce the risk of nerve damage and blindness.
Betaxolol works by reducing the production of aqueous humor in the eye. That way, the pressure in the eye is reduced. Betaxolol can be used as a single treatment or in combination with other drugs.
