Title
(EN) ACRYLIC ENTERIC COATING COMPOSITIONS
(FR) COMPOSITIONS UTILISEES POUR FORMER DES REVETEMENTS GASTRO-RESISTANTS ACRYLIQUES
Abstract
(EN) A non-toxic, edible, enteric film coating, dry powder composition for use in making an aqueous enteric suspension which may be used in coating pharmaceutical tablets comprises: a) an acrylic resin, said resin comprising i) from 20 to 85 percent by weight of at least one alkyl acrylate or alkyl methacrylate moiety, ii) from 80 to 15 percent by weight of at least one vinyl or vinylidene moiety having a carboxylic acid group capable of salt formation, and iii) from 0 to 30 percent by weight of at least one other vinyl or vinylidene moiety copolymerizable with i) and ii), b) an alkalizing agent capable of reacting with the acrylic resin such that, after reaction, 0.1 to 10 mole percent of the acidic groups in 1a-ii) are present in the salt form, and c) detackifier.
(FR) Une composition de poudre sèche pour un revêtement gastro-résistant mince non toxique et comestible destinée à être utilisée dans la fabrication d'une suspension gastro-résistante pouvant être utilisée pour le pelliculage de comprimés pharmaceutiques comprend : a) une résine acrylique laquelle contient i) entre 20 et 85 pour cent en poids d'au moins une fraction acrylate d'alkyle ou méthacrylate d'alkyle, ii) entre 80 et 15 pour cent en poids d'au moins une fraction vinyle ou vinylidène comportant un groupe acide carboxylique capable de former un sel, et iii) entre 0 et 30 pour cent en poids d'au moins une fraction vinyle ou vinylidène copolymérisable avec i) et ii) ; b) un agent d'alcalinisation capable de réagir avec la résine acrylique de sorte que, après la réaction, entre 0,1 et 10 moles pour cent des groupes acides dans 1a-ii) soient présents sous forme de sel ; et c) un agent supprimant le caractère collant.
