COREG CR vs KERLONE
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, myocardial contractility, and blood pressure.
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.
10 mg orally once daily; may increase to 20 mg once daily if needed. Maximum 20 mg/day.

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 is 8-12 hours in healthy adults; may extend to 15-20 hours in renal impairment (CrCl <30 mL/min).
Renal (16% unchanged, 60% as glucuronide conjugates), biliary/fecal (20%)
Primarily renal excretion of unchanged drug and metabolites (70-80% unchanged; 20-30% as glucuronide or sulfate conjugates). Biliary/fecal excretion accounts for less than 5%.
