Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Class Ic antiarrhythmic; blocks cardiac sodium channels, slowing phase 0 depolarization and reducing conduction velocity in atrial and ventricular myocardium.
Class III antiarrhythmic agent; prolongs cardiac action potential duration by blocking potassium channels (IKr), primarily affecting the atria and ventricles.
200-300 mg orally every 8 hours; maximum 900 mg/day.
Intravenous loading: 150 mg over 10 minutes, then 1 mg/min for 6 hours, followed by maintenance infusion of 0.5 mg/min. Oral: 400 mg twice daily for loading (total 1200 mg/day) for 7-10 days, then maintenance 200-400 mg once daily.

3-12 hours (mean ~6 hours); prolonged in hepatic or renal impairment.
Terminal elimination half-life of 58 days (range 25-110 days) due to extensive tissue distribution and slow release from lipid stores. Steady-state concentrations require approximately 3-6 months of chronic dosing.
Primarily hepatic metabolism; renal excretion of unchanged drug accounts for <1% of a dose; approximately 10-20% excreted in feces via bile.
Primarily hepatic metabolism; <1% excreted unchanged in urine. Biliary excretion of metabolites is significant, with approximately 30-40% eliminated in feces. Renal excretion accounts for ~15-20% of total clearance as metabolites.
