摘要 |
Provided are a coating composition for delayed release preparation capable of releasing a drug promptly in the stomach, without causing a time-dependent change, after a time (lag time) in which a solid preparation does not release the drug; and a solid preparation obtained by coating of the coating composition. More specifically, provided are a coating composition comprising at least a nonionic water-soluble cellulose ether and a cellulose-based enteric base material, wherein a weight ratio of the nonionic water-soluble cellulose ether to the cellulose-based enteric base material is from 95:5 to 65:35; and a solid preparation comprising at least a drug-containing core and the coating composition which covers the core, wherein the preparation can permit prompt dissolution of the drug in a stomach after a lag time.
