Abstract: 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.

Abstract: An oral fast-disintegrating tablet includes many tiny particles of slowly-releasable ascorbic acid, and a fast-disintegrating ingredient mixed with the many tiny particles that are dispersedly mixed with the fast-disintegrating ingredient. Each tiny particle is composed of a nucleus, an ascorbic layer and a release-control layer. The nucleus is coated with the ascorbic-acid layer and then with the releasing control layer to become a slowly-releasable particle. The tiny particles are mixed with the fast-disintegrating ingredient, which is composed of a mixture of ascorbic acid, water excipient, microcrystalline cellulose, a diluent agent, and disintegrant. So the tablet can be disintegrated swiftly in a mouth, and the tiny particles can enter the stomach and intestines with saliva to be slowly released, sustainingly absorbed by the organs.

Abstract: The present invention discloses a high-bioavailability particle coated with fungicide and polymer, which mainly comprises: (a) a coating layer including fungicide, a polymer, an acidic substance, talc, a bonding agent, ethanol and dichloromethane; (b) an anticoagulant layer including talc, hydroxypropyl methylcellulose (HPMC) and a plasticizer; and (c) a particulate core having a diameter ranging from 300 ?m to 500 ?m (30˜50 mesh). In the present invention, the talc is added to prevent the particulate cores from aggregating. In addition, the particulate cores are small-sized enough and the polymer and the acidic substance are added to the coating layer, so that solubility is increased and bioavailability is thus improved.
