التداخل بين فليكاينيد وفيراباميل

Flecainide A study in healthy volunteers showed that the concomitant administration of flecainide and verapamil may have additive effects on myocardial contractility, AV conduction, and repolarization.

Concomitant therapy with flecainide and verapamil may result in additive negative inotropic effect and prolongation of atrioventricular conduction.

Because both of these drugs have negative inotropic properties and the effects of coadministration with flecainide acetate are unknown, neither disopyramide nor verapamil should be administered concurrently with flecainide acetate unless, in the judgment of the physician, the benefits of this combination outweigh the risks.

There has been little experience with the coadministration of flecainide acetate and either disopyramide or verapamil .
