CONTROLLED RELEASE PREPARATION CONTAINING CILOSTAZOLAND PROCESS FOR THE PREPARATION THEREOF

摘要

A controlled release preparation which comprises particles containing cilostazol or its pharmaceutically acceptable salt dispersed in a solubilizing agent and an erodible material encasing said particles which is capable of forming a hydrogel, can maintain a constant level of cilostazol in the blood through its slow release during its prolonged residence time in the stomach and intestines, thereby minimizing adverse effects caused by rapid release of the drug or solubilizing agent.
