发明名称 CONTROLLED-RELEASE SOLID PREPARATION WITH PARTIAL COATING
摘要 Disclosed is a controlled-release solid preparation, which consists of an internal core and a coating layer, wherein part of the surface of the internal core is not covered with the coating, and is exposed to the surface of the solid preparation. Since the medicament just releases at the exposed part, the aim of controlled release can be achieved by controlling this exposed surface area.
