The electrophysiologic effects of intravenous lorcainide (2.2 mg/kg) in 10 patients were compared with the electrophysiologic effects of oral lorcainide (mean dose 400 mg/day for 8 days) in 11 patients, all with recurrent ventricular tachycardia that could be induced with programmed stimulation. Intravenous and oral lorcainide resulted in similar prolongation of the QRS, QT, and HV intervals, but only oral lorcainide resulted in prolongation of the AH interval and atrial and ventricular effective refractory periods. After both oral and intravenous lorcainide, ventricular tachycardia could still be induced, but the arrhythmia was slower and better tolerated hemodynamically. The mean plasma lorcainide level during a maintenance intravenous infusion was 1254 +/- 662 ng/ml compared with a lorcainide level of 562 +/- 41 ng/ml and a norlorcainide level of 1212 +/- 653 ng/ml after oral dosing. No norlorcainide was detected in plasma after intravenous lorcainide. These data suggest that the short-term electrophysiologic effects of intravenous lorcainide may be different from those of short-term therapy with the oral drug. These differences should be considered during short-term studies of lorcainide.

Comparison of the electrophysiologic effects of intravenous and oral lorcainide in patients with recurrent ventricular tachycardia.
