COREG CR vs ESMOLOL HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonselective beta-1, beta-2, and alpha-1 adrenergic receptor antagonist; no intrinsic sympathomimetic activity; reduces myocardial oxygen demand, decreases peripheral vascular resistance, and suppresses renin-angiotensin-aldosterone system.
Selective beta-1 adrenergic receptor antagonist; reduces heart rate, contractility, and blood pressure by blocking catecholamine effects at beta-1 receptors.
Initial dose 20 mg orally once daily for patients with heart failure; may increase at 2-week intervals to a target dose of 80 mg once 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 is 7-10 hours; due to controlled-release formulation, effective half-life is prolonged to support once-daily dosing
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 (16% unchanged, 60% as glucuronide conjugates), biliary/fecal (20%)
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.
