Precautions
General
Topically applied beta-adrenergic blocking agents may be absorbed systemically. The same types of cardiovascular and pulmonary and other adverse reactions found with systemic
administration of these agents may occur with topical administration. For example, severe respiratory reactions, including death due to exacerbation of bronchospasm in patients with
asthma, and rarely death in association with cardiac failure, have been reported with ophthalmic application of beta- adrenergic blocking agents.
Cardiovascular
While ophthalmic betaxolol hydrochloride 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. When beginning therapy with betaxolol patients with a history of severe cardiac disease should be monitored closely for signs of cardiac failure.
Treatment with ophthalmic betaxolol hydrochloride should be discontinued at the first sign of cardiac failure.
Because of potential effects of beta-blockers on blood pressure and pulse (e.g. hypotension, bradycardia), use with caution in patients with cerebrovascular insufficiency, untreated
phaeochromocytoma or metabolic acidosis, since beta-adrenergic blocking agents can adversely affect such diseases.

Mechanism of Action
Betaxolol is a cardioselective beta-blocker which has greater affinity for beta1-receptors and has little or no effect on beta2-receptors. It lacks intrinsic sympathomimetic but has little membrane-stabilising activity. It also causes the reduction of intraocular pressure by decreasing the production of aqueous humour.
