摘要: The present invention provides a core of predominately microcrystalline cellulose, on which an active drug is layered onto the core via solution coating. The coated particles have a narrower particle size distribution than coated granules provided by other processes. An optional final coating of a pharmaceutically acceptable polymeric coating is provided to provide tastemaking or controlled release, and protection of the drug-layered particles.
