Moricizine is an antiarrhythmic agent previously marketed as Ethmozine. It was used for prophylaxis and treatment of serious and life-threatening ventricular arrhythmias. In 2007 it was withdrawn and discontinued for commercial reasons. Moricizine can be administered intravenously but was more commonly provided as an oral formulation.

Sample Use Guides

In Vivo Use Guide

Patients with greater than or equal to 30 ventricular premature complexes (VPCs) per hour were given moricizine HCL (816 +/- 103 mg daily) as a three times oral daily dose. Moricizine suppressed 81% of VPCs alone and 87% of VPCs in combination with 120 mg of propranolol.

Route of Administration: Oral

In Vitro Use Guide

Single ventricular myocytes from guinea-pig hearts were prepared by enzymatic dissociation. Isolated single cells were transferred to a recording chamber of an inverted phase-contrast microscope which was maintained at 34 - 35 deg-C. Membrane currents were recorded by using whole-cell patch-clamp technique using an amplifier. Application of 1O micro-M moricizine was started at 7 minutes and continued up to 13 minutes after the formation of whole cell configuration. In the absence of drug, the current decayed with time and the average value of relative currents at 20 min was 0.48 ± 0.11. In the presence of 10 micro-M moricizine, the tail currents decreased progressively with time and the minimum value of 0.29 was reached at 13 min after rupture of the membrane (or 6 min after the application of moricizine).
