BETOPTIC vs ESMOLOL HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-1 adrenergic receptor antagonist; reduces intraocular pressure by decreasing aqueous humor production.
Selective beta-1 adrenergic receptor antagonist; reduces heart rate, contractility, and blood pressure by blocking catecholamine effects at beta-1 receptors.
Instill 1 drop of 0.5% solution 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; titrate by 25-50 mcg/kg/min every 5-10 minutes up to 200 mcg/kg/min.

Terminal elimination half-life: 4–5 hours. With topical ophthalmic administration, systemic absorption is minimal, so half-life refers to IV data.
Terminal elimination half-life: approximately 9 minutes in adults (range 4–13 min); in patients with hepatic impairment: unchanged; in severe renal impairment: prolonged to 12–20 min due to metabolite accumulation. Clinically, rapid offset (within 20–30 min) allows for titration.
Renal (fecal <5%). 60% as unchanged drug, 40% as inactive metabolites.
Rapid metabolism by red blood cell esterases to inactive acid metabolite (ASL-8123) and methanol; <2% excreted unchanged in urine; primarily renal elimination of metabolites.
