Abstract

Nouvelle formulation polymère à administrer par voie orale contrôlée adaptée à l'administration, en une fois par jour, de composés de valproate, tels que du sodium de divalproex. Cette formulation présente des avantages importants par rapport aux formulations de valproate à libération lente de la technique antérieure. Cette formulation réduit au minimum la variation entre des concentrations plasmatiques maximales et minimales de valproate sur une période de dosage de 24 heures. Cette formulation suit un modèle de libération d'ordre zéro, produisant ainsi des concentrations plasmatiques sensiblement uniformes de valproate, une fois que des concentrations plasmiques d'équilibre ont été obtenues. Grâce à cela, on obtient une incidence considérablement inférieure des effets secondaires chez les patients consommant une telle formulation.
