BETAGAN is a brand name for the medication levobunolol, which belongs to a class of drugs known as beta-blockers. It is primarily used in the form of eye drops and is prescribed for the treatment of glaucoma, a condition characterized by increased pressure in the eye that can lead to damage to the optic nerve and loss of vision if not treated. Levobunolol works by reducing the production of fluid within the eye, thereby lowering the pressure inside the eye. It is effective in managing and preventing the progression of glaucoma and is used under the guidance of a healthcare professional. Patients are advised to follow the prescribed dosage and instructions carefully to ensure the best outcomes while minimizing potential side effects.
