Process for producing an amorphous optically active isomer of lansoprazole |
摘要 |
It is intended to provide a process for producing unstable amorphous benzimidazole compounds having a proton pump inhibitor function, and stable solid preparations for medicinal use containing these compounds which are produced by blending such an amorphous benzimidazole compound with a nontoxic base such as a basic inorganic salt, forming an intermediate coating layer on the layer containing the active ingredient and further forming an enteric coating layer or a release-controlling coating layer. |
