Abstract[English]
A pharmaceutical formulation comprising a single population of IR/XR particles of viloxazine, wherein each IR/XR particle of the single population of IR/XR particles comprising an extended- release region (XR) of the viloxazine; and an immediate-release region (IR) of the viloxazine, wherein the immediate-release region (IR) of the viloxazine is coated surrounding the extended- release region (XR) of the viloxazine, wherein the extended-release region (XR) is formed as an extended-release particle and the immediate-release region (IR) is formed as a coat surrounding the extended-release particle. A process for making the single population of IR/XR particles of viloxazine comprising the steps in the sequence of: (a) making the extended-release (XR) particles of the viloxazine; and (b) making the immediate-release (IR) coat of the viloxazine surrounding the extended-release (XR) particles of the viloxazine.[French]
L'invention concerne une formulation pharmaceutique comprenant une population unique de particules IR/XR de viloxazine, chaque particule IR/XR de la population unique de particules IR/XR comprenant une région à libération prolongée (XR) de viloxazine ; et une région à libération immédiate (IR) de viloxazine, la région à libération immédiate (IR) de viloxazine étant déposée en entourant la région à libération prolongée (XR) de viloxazine, la région à libération prolongée (XR) étant formée d'une particule à libération prolongée et la région à libération immédiate (IR) étant formée sous la forme d'un revêtement entourant la particule à libération prolongée.
