Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Class III antiarrhythmic agent; prolongs cardiac action potential duration and refractory period by blocking potassium channels, primarily IKr.
Selective beta-1 adrenergic receptor antagonist; reduces cardiac output, heart rate, and renin release from kidneys.
Oral: 80 mg twice daily; may increase up to 160 mg twice daily as needed.
Adults: Initial dose 2.5-5 mg orally once daily, titrate to 10 mg once daily; maximum 20 mg once daily.

12 hours (10-20 hours) in patients with normal renal function; prolonged in renal impairment, requiring dose adjustment
Terminal elimination half-life is 9–12 hours (mean 11 hours), allowing once-daily dosing. Half-life may be prolonged in renal impairment (creatinine clearance <40 mL/min) and in elderly patients.
Renal: >90% unchanged drug (sotalol) in urine; biliary/fecal: <10%
Approximately 50% excreted unchanged in urine; remainder metabolized in liver to inactive metabolites, then renally excreted. Fecal excretion is negligible (<2%). Total renal clearance accounts for ~60-70% of elimination.
