Title (EN) SYSTEM FOR CONTROLLED DRUG DELIVERY COMPRISING BIODEGRADABLE POLYMER MICROPARTICLES
(FR) SYSTÈME D'ADMINISTRATION CONTRÔLÉE DE MÉDICAMENT COMPORTANT DES MICROPARTICULES POLYMÈRES BIODÉGRADABLES
Abstract: front page image
(EN)The present invention relates to systems for controlled release, such as controlled drug release. In particular, it relates to systems comprising biodegradable polymer microparticles based on hydrophilic polysters having pendant hydroxyl groups and obtainable from water-in-oil-in-water emulsions for controlled release of drugs and therapeutics, such as DNA, proteins, peptides. Further, the invention relates to a method to prepare such systems and the use of such systems.
(FR)La présente invention concerne des systèmes pour une libération contrôlée, telle qu'une libération contrôlée de médicament. En particulier, l'invention porte sur des systèmes comportant des microparticules polymères biodégradables à base de polyesters hydrophiles ayant des groupes hydroxyle latéraux qui peuvent être obtenues à partir d'émulsions eau-dans l'huile-dans l'eau pour une libération contrôlée de médicaments et de produits thérapeutiques, tels que de l'ADN, des protéines, des peptides. En outre, l'invention concerne un procédé de préparation de tels systèmes et l'utilisation de tels systèmes.
