摘要

UNIT DOSE WITH RELEASE OF PHARMACEUTICAL FORMULATION WITH CONTROLLED RELEASE, PROCESS FOR THEIR PREPARATION, AS WELL AS USING A POLY (METHYL ACRYLATE, METHYL METHACRYLATE) COPOLYMER. A neutral poly (ethyl acrylate, methyl methacrylate) copolymer is employed as a carrier in the manufacture of pharmaceutical formulations containing an active ingredient. The formulations are preferably prepared by melt extrusion and may have rubber characteristics and may exhibit tamper resistance.
