Mechanism of action
This a beta-1 selective beta blocker that reduces the aqueous humor production, increases drainage, and alters the blood flow of the eye, thus lowering the pressure.
Treatment of open angle glaucoma and ocular hypertension.
Instill 1 drop of the 0.25% solution into eye every 12 hours twice every day. Increase to 0.5% solution if needed. Decrease to 1 drop every day if condition is controlled. Consult your doctor for the correct dosage.
Use with caution in patients with/during:
- Betaxolol should NOT be used in patients with preexisting cardiac disease, such as severe bradycardia, advanced AV block, cardiogenic shock, coronary artery disease, vasospastic angina, or congestive heart failure, particularly those with severe left ventricular dysfunction.
- Asthma or pulmonary disease (COPD, emphysema, bronchitis)
- Diabetes mellitis because it can mask symptoms of hypoglycemia
- Hyperthyroidism because it may mask tachycardia
- Using an oral beta blocker

- Raynaud's disease or peripheral vascular disease
- Myasthenia gravis
- Pregnancy, breastfeeding, or in children
