Abstract

Abstract Translated from French La présente invention concerne des microcapsules biodégradables à base de sérumalbumine, leur préparation et leur application à la libération in situ de médicaments. Les microcapsules, selon la présente invention, se caractérisent en ce que leur paroi est constituée par de la sérumalbumine dont une partie est réticulée par polymérisation interfaciale à l'aide d'un réactif bifonctionnel acylant, et dont l'autre partie, non réticulée, est dénaturée à l'aide d'un alcool. The present invention relates to biodegradable microcapsules based on serum albumin, their preparation and their application to the in situ release of drugs. The microcapsules, according to the present invention, are characterized in that their wall is constituted by serum albumin, part of which is crosslinked by interfacial polymerization using a bifunctional acylating reagent, and the other part of which is not crosslinked, is denatured using alcohol.
