Effect

Levobetaxolol inhibits the beta-1-adrenergic receptor. When applied topically, it reduces intra-ocular pressure (IOP) by 16-23% depending on time of day and the individual. It is indicated for IOP reduction in patients with open-angle glaucoma or ocular hypertension. Levobetaxolol has fewer cardiovascular side effects than other beta blockers.

Contraindications and side effects

Levobetaxolol should not be used by people who have sinus bradycardia, atrioventricular block, cardiogenic shock, or overt cardiac failure.

The drug has been associated with bradycardia and hypertension.
