发明名称 Multiparticulate Pharmaceutical Form Comprising Pellets With a Matrix Which Influences the Delivery of a Modulatory Substance
摘要 The invention relates to a multiparticulate pharmaceutical form, comprising pellets with a multilayer structure for controlled active ingredient release, comprising a) optionally a neutral core (nonpareilles), b) an inner controlling layer comprising a substance having a modulating effect, which is embedded in a matrix which influences the delivery of the modulatory substance and which comprises pharmaceutically usable polymers, waxes, resins and/or proteins, and where appropriate an active ingredient, c) an active ingredient layer comprising an active pharmaceutical ingredient and, where appropriate, a substance having a modulating effect, d) an outer controlling layer comprising at least 60% by weight of one or a mixture of a plurality of (meth) acrylate copolymers where the outer controlling layer has a thickness from 20 to less than 55 mum and contains 0,1 to 10% by weight of glycerol monostearate, where the multiparticulate pharmaceutical form contains 20 to 60% by weight of the pellets, which are compressed in mixture with 80 to 40% by weight of an outer phase which consists from 50 to 100% by weight of a cellulose or a derivate of cellulose and optionally 0 to 50% by weight of further pharmaceutical excipients.
