Abstract
The present invention pertains to a quick disintegrating tablet in buccal cavity, characterized in that drug-containing particles with a mean particle diameter of approximately 50 to approximately 250 μm and an apparent specific gravity of approximately 0.5 to approximately 1.2 consisting of a bitter tasting drug and/or drug of inferior fluidity and a pharmaceutical preparation carrier and obtained by spray drying are added to a quick disintegrating tablet in buccal cavity comprising a drug and a saccharide. Moreover, the present invention pertains to a method for manufacturing drug-containing particles having a specific mean particle diameter and specific apparent gravity by dissolving and suspending a bitter tasting drug and/or drug of inferior fluidity and a pharmaceutical preparation carrier to a high concentration in terms of solid concentration in a solvent and spray drying this liquid and a method for manufacturing a quick disintegrating tablet in buccal cavity comprising the particles.
