® (betaxolol hydrochloride ophthalmic suspension) 0.25% is indicated for the treatment of elevated intraocular pressure (IOP) in patients with chronic open-angle glaucoma or ocular hypertension. BETOPTIC S is a beta-adrenergic receptor inhibitor indicated for the treatment of elevated intraocular pressure (IOP) in patients with chronic open-angle glaucoma or ocular hypertension. ( 1 )

is contraindicated in patients with: sinus bradycardia greater than a first degree atrioventricular (AV) block cardiogenic shock patients with overt cardiac failure hypersensitivity to any component of this product Hypersensitivity to any component of this product. ( 4 ) Sinus bradycardia, second or third degree atrioventricular (AV) block, overt cardiac failure, and cardiogenic shock. ( 4 )

Systemic Absorption : Same adverse reactions found with systemic administration of beta-adrenergic receptor inhibitors may occur with topical ophthalmic administration. ( 5.1 ) Cardiac Failure : Discontinue treatment at the first signs of cardiac failure. ( 5.2 ) Diabetes Mellitus : Beta-adrenergic receptor inhibitors may mask the signs and symptoms of acute hypoglycemia. Administer with caution in diabetic patients subject to hypoglycemia. ( 5.3 ) Thyrotoxicosis : Beta-adrenergic receptor inhibitors may mask certain clinical signs (e.g., tachycardia) or hyperthyroidism. ( 5.4 ) 5.1 Systemic Absorption As with many topically applied ophthalmic drugs, this drug is absorbed systemically. The same adverse reactions found with systemic administration of beta-adrenergic receptor inhibitors may occur with topical administration. For example, severe respiratory reactions and cardiac reactions, including death due to bronchospasm in patients with asthma, and death due to cardiac failure, have been reported with topical application of beta-adrenergic receptor inhibitors. 5.2 Cardiac Failure BETOPTIC S has been shown to have a minor effect on heart rate and blood pressure in clinical studies. Caution should be used in treating patients with a history of cardiac failure or heart block. Treatment with BETOPTIC S should be discontinued at the first signs of cardiac failure. 5.3 Diabetes Mellitus Beta-adrenergic receptor inhibitors should be administered with caution in patients subject …

8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies of BETOPTIC S administration in pregnant women to inform a drug-associated risk. There are limited data with the use of betaxolol eye drops in pregnant women. Epidemiological studies have not revealed malformative effects but show a risk for intrauterine growth retardation when beta-blockers are administered by the oral route. In animal reproductive studies, no drug-induced maternal toxicity or teratogenicity was observed at clinically relevant doses (see Data) . Because animal reproductive studies are not always predictive of human response, BETOPTIC S should be used during pregnancy only if the potential benefit …
