Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Betaxolol is a cardioselective beta-1 adrenergic receptor antagonist. In ophthalmic use, it reduces intraocular pressure by decreasing the production of aqueous humor, likely through blockade of beta-2 receptors in the ciliary epithelium.
Selective beta-1 adrenergic receptor antagonist with no intrinsic sympathomimetic activity or membrane stabilizing activity. Reduces heart rate, myocardial contractility, and blood pressure by blocking catecholamine effects at beta-1 receptors predominantly in cardiac tissue.
Instill 1 drop in the affected eye(s) twice daily.
Loading dose: 500 mcg/kg IV over 1 minute, followed by maintenance infusion of 50 mcg/kg/min IV for 4 minutes. Titrate by 50 mcg/kg/min increments every 4 minutes as needed to maximum of 200 mcg/kg/min. For double-strength (20 mg/mL) formulation, adjust infusion rate accordingly.

Terminal elimination half-life is approximately 4–6 hours in adults; prolonged in renal impairment and in elderly patients due to decreased clearance.
Terminal elimination half-life is approximately 9 minutes. Clinical context: ultra-short acting beta-blocker, steady state achieved within 30 minutes.
Renal: 0.3% unchanged; extensive hepatic metabolism to inactive metabolites; biliary/fecal elimination of metabolites accounts for the majority of excretion; total renal elimination of drug and metabolites is approximately 80%, with the remainder via feces.
Rapid metabolism by red blood cell esterases; metabolites are inactive. Less than 2% excreted unchanged in urine.
