The present invention relates to a hydrogel composition for transdermal drug delivery, more specifically to a hydrogel composition for transdermal drug delivery containing acrylate polymers like acrylic acid polymer, methacrylic acid polymer, alkyl acrylate polymer, alkyl methacrylate polymer or copolymers thereof as compatibilizers which enable both hydrophilic and lipophilic permeation enhancers to be applicable in the hydrogel composition in order to effectively control skin penetration of drugs.
L'invention concerne une composition d'hydrogel destinée à l'administration transdermique de médicaments, et plus spécifiquement une composition d'hydrogel destinée à l'administration de médicaments, contenant des polymères de type acrylate tels qu'un polymère acide acrylique, un polymère acide méthacrylique, un polymère acrylate d'alkyle, un polymère méthacrylate d'alkyle ou des copolymères de ceux-ci, qui servent d'agents de compatibilisation permettant l'utilisation combinée d'agents favorisant la perméation hydrophiles et lipophiles dans la composition d'hydrogel, de manière à assurer une régulation efficace de la pénétration transdermique des médicaments.
