Pregnancy Category

Name : Not Classified

Description

FDA has not yet classified the drug into a specified pregnancy category.

Mode of Action

Propafenone is a class 1C antiarrhythmic drug with local anaesthetic effects, and a direct stabilising action on myocardial membranes. The electrophysiological effect manifests itself in a reduction of upstroke velocity (Phase 0) of the monophasic action potential. In Purkinje fibers, and to a lesser extent myocardial fibers, propafenone reduces the fast inward current carried by sodium ions. Diastolic excitability threshold is increased and effective refractory period prolonged. Propafenone reduces spontaneous automaticity and depresses triggered activity.

Interaction

Effect may be potentiated by local anesth, beta-blockers, TCA. May increase plasma level of propranolol, metoprolol, desipramine, cyclosporin, digoxin, theophylline. Plasma conc may rise when taken simultaneously w/ cimetidine or quinidine. May enhance effect of anticoagulant. Simultaneous administration w/ phenobarb or rifamycin may decrease propafenone plasma conc, possibly in sub-therapeutic levels.

Pregnancy Category Note

Pregnancy There are no studies in pregnant women; available data from published case reports and several decades of postmarketing experience with use in pregnancy have not identified any drug-associated risks of miscarriage, birth defects, or adverse maternal or fetal outcomes; untreated arrhythmias during pregnancy may pose a risk to pregnant woman and fetus; the drug and its metabolite, 5-OH-propafenone, cross the placenta in humans Incidence of VT is increased and may be more symptomatic during pregnancy; ventricular arrhythmias most often occur in pregnant women with underlying cardiomyopathy, congenital heart disease, valvular heart disease, or mitral valve prolapse; breakthrough arrhythmias may occur during pregnancy, as therapeutic treatment levels may be difficult to maintain due to increased volume of distribution and increased drug metabolism inherent in pregnant state The drug and its metabolite have been shown to cross placenta; adverse reactions such as fetal/neonatal arrhythmias have been associated with use of other antiarrhythmic agents by pregnant women; fetal/neonatal monitoring for signs and symptoms of arrhythmia is recommended during and after treatment of pregnant women Animal data In animal studies, propafenone was not teratogenic; at maternally toxic doses (ranging from 2 to 6 times maximum recommended human dose [MRHD]), there was evidence of adverse developmental outcomes when administered to pregnant rabbits and rats during organogenesis or when administered to pregnant rats during mid-gestation through weaning of their offspring Infertility Based on human and animal studies, may transiently impair spermatogenesis in males; reversible decreases in spermatogenesis have been demonstrated in monkeys, dogs, and rabbits after lethal or near-lethal intravenous doses of the drug Labor or Delivery Risk of arrhythmias may increase during labor and delivery; patients should be monitored continuously for arrhythmias during labor and delivery Lactation Propafenone and its active metabolite, 5-OH-propafenone, are present in human milk, but levels are likely to be low; there are no data on effects on breastfed infant or on milk production The developmental and health benefits of breastfeeding should be considered along with the mother?s clinical need for propafenone and any potential adverse effects on breastfed infant from propafenone or from underlying maternal condition
