Orally administrable pharmaceutical preparation of improved flavoring characteristics.

摘要

An orally administrable pharmaceutical preparation of improved flavour characteristics comprises a core material containing a drug having a coating layer applied to its surface, the coating layer comprising a particulate polymeric substance having an average particle diameter of not more than 60 microns and being soluble in gastric juice. The preparation is prepared by causing minute liquid droplets of a volatile liquid containing a drug and, optionally, a gastric juice-soluble polymeric substance to fall onto a fluidised power bed composed of a gastric juice-soluble particulate polymeric substance having an average particle diameter of not more than 60 microns, thereby to coat the surface of the liquid droplets with the particulate polymeric substance; and drying the coated particles.
