The invention concerns a storage stable pharmaceutical formulation comprising preferably two active compounds in a non-swellable diffusion matrix, whereby the compounds are released from the matrix in a sustained, invariant and, if several compounds are present, independent manner and the matrix is determined with respect to its substantial release characteristics by ethylcellulose and at least one fatty alcohol. The invention also concerns methods for producing such pharmaceutical formulations.
本发明涉及一种贮藏稳定的药物制剂,该制剂最好由两种活性化合物组成,并置于非膨胀扩散基质中,其中的化合物以持续、不变的方式从基质中释放,如果存在多种化合物,则以独立的方式释放,基质由
乙基纤维素和至少一种
脂肪醇决定其实质性释放特性。本发明还涉及生产这种药物制剂的方法。
