BETAPACE AF vs NADOLOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sotalol is a class III antiarrhythmic agent that also has non-cardioselective beta-adrenergic receptor blocking activity. It prolongs the cardiac action potential duration by blocking potassium channels (IKr), thereby prolonging the QT interval and refractory periods.
Non-selective beta-adrenergic receptor antagonist (beta-blocker) that competitively blocks beta1 and beta2 receptors, reducing heart rate, myocardial contractility, and blood pressure.
80 mg orally twice daily. For atrial fibrillation/flutter, initiate at 80 mg twice daily; may increase after 2-3 days to 120 mg twice daily if needed. Maximum 120 mg twice daily.
40 to 80 mg orally once daily, may be increased at 3-7 day intervals up to 240 mg once daily.

Terminal elimination half-life: 12 hours (range 10–20 hours) in patients with normal renal function; prolonged in renal impairment (up to 42 hours in severe impairment).
Terminal elimination half-life: 14–24 hours (average 20 hours); prolonged in renal impairment (up to 45 hours) allowing once-daily dosing
Primarily renal (unchanged drug and metabolites); approximately 40% excreted as unchanged sotalol in urine, with additional metabolites via fecal route (~10%). Biliary excretion minimal (<5%).
Renal (unchanged drug) 75-85%; fecal/biliary <5%
