| 20110280939 | ORAL PARTICLE INCLUDING PSEUDOEPHEDRINE HYDROCHLORIDE AND CETIRIZINE DIHYDROCHLORIDE - The present invention relates to an oral particle including pseudoephedrine hydrochloride and cetirizine dihydrochloride, which primarily includes a nucleus having a diameter ranging 25˜40 mesh, a pseudoephedrine-hydrochloride layer coated outside the nucleus with a coating solution composed of pseudoephedrine hydrochloride, a binder, a lubricant and pure water/alcohol, a release-control layer coated outside the pseudoephedrine-hydrochloride layer, and a cetirizine-dihydrochloride layer coated outside the release-control layer with a coating solution composed of cetirizine dihydrochloride, a binder, a lubricant and pure water/alcohol. Accordingly, by distributing pseudoephedrine hydrochloride and cetirizine dihydrochloride into hundreds of the particles and controlling the dissolution rate with the release-control layer, the particles can perform good absorption efficiency, and quick, stable and long-term edicinal effect. | 11-17-2011 |
