Optipranolol is part of the Beta Blockers class and treats Glaucoma. Beta blockers are used to treat hypertension, angina, migraines, atrial fibrillation, essential tremor, heart attack, heart failure, ventricular arrhythmia, and glaucoma. They work by blocking certain receptors to reduce heart rate, dilating blood vessels for better blood flow, and reducing excess eye fluid to decrease eye pressure. Optipranolol is only available as a brand name drug. Get Metipranolol for as low as $21.73, save up to 80% off the average retail price for the most common version, by using a GoodRx coupon.
