METHOD FOR PREPARING EPERISONE SUSTAINED RELEASE MICROSPHERE, AND COMPOSITE PREPARATION OF EPERISONE SUSTAINED RELEASE MICROSPHERE AND ACECLOFENAC

摘要

The present invention relates to a method for preparing an eperisone sustained release microsphere, and a composite preparation of a eperisone sustained release microsphere and aceclofenac and, more specifically, to: a method for preparing an eperisone sustained release microsphere, the method using, as a microsphere seed, one or more sugars selected from microcrystalline cellulose, anhydrous lactose, starch, sugar, maltitol, or mannitol, and coating eperisone, an acidifying agent, and a release control polymer; and a composite preparation of an eperisone sustained release microsphere and aceclofenac.
