Abstract
Parmi les neuroleptiques disponibles, l'amisulpride est de plus en plus prescrit. De par son affinité sélective dose-dépendante aux récepteurs dopaminergiques, il est possible de moduler les effets de cette substance montrant des propriétés antidépressives à faible dose et agissant comme un puissant antipsychotique à forte dose. Toutefois, l'amisulpride induit une prolongation dose-dépendante de l'intervalle QT ce qui peut potentialiser la survenue d'arythmies ventriculaires, souvent fatales lorsque sa consommation est concomitante à celles d'autres médicaments ou stupéfiants allongeant l'intervalle QT. Cependant, la littérature scientifique demeure peu documentée en ce qui concerne la détermination de concentrations sanguines thérapeutiques, toxiques et létales. Après avoir présenté les propriétés pharmacodynamiques et pharmacocinétiques de l'amisulpride, nous nous proposons de définir plus précisément les seuils sanguins de concentrations thérapeutiques, toxiques et létales pour cette molécule illustrée par la revue des cas mortels impliquant l'amisulpride en Suisse romande depuis 2005.
Among the available neuroleptic drugs, amisulpride is increasingly prescribed. Thanks to its dose-dependent selective affinity for dopamine receptors, it is possible to modulate the effects of this substance showing antidepressant properties at low dose and acting as a powerful antipsychotic at high dose. However, amisulpride induces a dose-dependent prolongation of the QT interval which may potentiate the occurrence of ventricular arrhythmias, often fatal when its consumption is concomitant with those of other drugs that prolong the QT interval. However, the scientific literature remains poorly documented with regard to the determination of therapeutic, toxic and lethal blood concentrations. After presenting the pharmacodynamic and pharmacokinetic properties of amisulpride, we propose to define more precisely the blood levels of therapeutic, toxic and lethal concentrations for this molecule illustrated by a review of the fatal cases involving amisulpride in Western Switzerland since 2005.
