Active-Ingredient-Containing Solid Dispersions Based on Diethylaminoethyl Methacrylate Copolymers

摘要

Described are solid dispersions of hydrophobic active ingredients and cationic copolymers of N,N-diethylaminoethyl methacrylate and methyl methacrylate in a weight ratio of the monomers of from 35:65 to 55:45. Also described are the preparation and use of such solid dispersions for pharmaceutical dosage forms.
