CARTROL vs ESMOLOL HYDROCHLORIDE IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CARTROL is a beta-1 selective adrenergic receptor antagonist. It inhibits the effects of catecholamines on beta-1 receptors in the heart, reducing heart rate, myocardial contractility, and blood pressure.
Selective beta-1 adrenergic receptor antagonist with rapid onset and short duration of action; reduces heart rate, myocardial contractility, and blood pressure; no intrinsic sympathomimetic activity or membrane stabilizing activity.
Adults: 2.5 mg orally twice daily, titrated up to maximum 10 mg twice daily.
Intravenous loading dose: 500 mcg/kg over 1 minute, followed by maintenance infusion: 50 mcg/kg/min for 4 minutes; if adequate response not achieved, repeat loading dose and increase maintenance infusion by 50 mcg/kg/min increments up to 200 mcg/kg/min.

Terminal elimination half-life is 6–8 hours in normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 9 minutes (range 6–12 min) in healthy adults; prolonged to 15–20 min in hepatic impairment. Clinical context: rapid offset allows precise titration.
Primarily renal excretion (approx. 70% unchanged drug), with 20% biliary/fecal, and 10% metabolism to inactive metabolites.
Rapid hydrolysis by esterases in blood and tissues to inactive acid metabolite (ASL-8123) and methanol. Less than 2% excreted unchanged in urine. Renal elimination of metabolite accounts for >80% of dose; <5% fecal.
