  • Quick disintegrating tablet in buccal cavity and production process thereof
    Publication number: 20050100598
    Abstract: The present invention relates to a quick disintegrating tablet in buccal cavity, comprising: a mixture, comprising a drug, a sugar (A), and an amorphous sugar (B), and after it is forming a tablet, it is humidified and dried. In particularly, the present invention relates to a quick disintegrating tablet in buccal cavity comprising: a mixture; comprising a drug, a sugar (A), and an amorphous sugar (B) which an amorphous-forming sugar in crystalline state is dissolved in a medicinally permitted solvent, the amorphous sugar is obtained from this solution by removing the solvent, and after it is forming a tablet, and it is humidified and dried. The tablet in the present invention is to provide stability against moisture at preserved, because the amorphous sugar changed to the crystalline state in a nonreversible reaction after it is humidified and dried in a manufacturing process.
