Terfenadine therapy: can we justify the risks?

چکیده

DEPUIS LA MISE EN VENTE DE LA TERFÉNADINE, antihistaminique non sédatif, il y a plus de 20 ans, des rapports sur des cas d’arythmie cardiaque et de mort subite associée à son utilisation ont entraîné son retrait du marché dans certains pays. Néanmoins, la terfénadine est toujours en vente au Canada. Les avantages qu’offre ce médicament pour contrôler les symptômes de la fièvre des foins ne l’emportent sûrement pas sur les risques d’effets indésirables qui peuvent être mortels. De plus, la disponibilité continue de ce médicament est injustifiée compte tenu des solutions de rechange sans danger qui existent.

SERIOUS ARRHYTHMIA INDUCED BY TERFENADINE-ERYTHROMYCIN INTERACTIONS

Since the introduction of our local manufacturing of terfenadine, we have observed and expressed our concern about a small but increasing number of serious ventricular arrhythmias associated with the use of this non sedating antihistamine. In January 1997 a case of torsade de pointes ventricular tachycardia was detected in a previously healthy woman taking terfenadine with erythromycin. El...

The Comparative Effects of Four Antihistamines on Isolated Rat Atria

It has been reported that some of H1 receptor antagonists have important effects on cardiovascular system. Terfenadine as a non-sedative H1 receptor antagonist has an arrhythmogenic activity. In this study we have shown the effects of four antihistamine drugs: terfenadine, loratadine, clemastine and diphenhydramine, on the rate and contractions of isolated rat atria. Terfenadine (1-10 µM) cause...

Zebrafish Larvae Model of Dilated Cardiomyopathy Induced by Terfenadine

BACKGROUND AND OBJECTIVES Dilated cardiomyopathy can be the end-stage of severe cardiac disorders and directly affects the cardiac muscle, inducing cardiomegaly and heart failure (HF). Although a wide variety of animal models are available to study dilated cardiomyopathy, there is no model to assess dilated cardiomyopathy with non-invasive, simple, and large screening methods. METHODS We deve...

A method for estimating pharmacokinetic risks of concentration-dependent drug interactions from preclinical data.

This article evaluates a novel approach for estimating the pharmacokinetic risks associated with drug interactions in populations. Preclinical pharmacokinetic and metabolism data are analyzed with a stochastic differential equation-based pharmacokinetic model that recognizes that the risks associated with known drug interactions involve deterministic and stochastic components. Specifically, a B...

Antihistamine terfenadine potentiates NMDA receptor-mediated calcium influx, oxygen radical formation, and neuronal death.

We previously reported that the histamine H1 receptor antagonist terfenadine enhances the excitotoxic response to N-methyl-D-aspartate (NMDA) receptor agonists in cerebellar neurons. Here we investigated whether this unexpected action of terfenadine relates to its antihistamine activity, and which specific events in the signal cascade coupled to NMDA receptors are affected by terfenadine. Low c...
