摘要：
When a mixture comprising 30 to 70% by weight of an enterosoluble cellulose derivative containing a monoester linkage with a polybasic acid, such as, hydroxypropyl methylcellulose phthalate, and 70 to 30% by weight of a digestive fluid-insoluble cellulose derivative, such as, ethylcellulose is used as a coating material for solid medicines, the rate of gradual release of active ingredients of the medicine in the intestinal tracts can be appropriately controlled.
