The present invention relates to a quick-disintegrating tablet in the buccal cavity comprising a drug, a diluent, and a saccharide with a relatively lower melting point than the drug and the diluent, which is obtained by uniformly mixing the saccharide with a low melting point in the tablet so that a bridge will be formed between said drug and/or said diluent particles by the product of melting and then solidification of this saccharide with a low melting point. Moreover, the present invention relates to a method of manufacturing a quick-disintegrating tablet in the buccal cavity comprising a drug, a diluent and a saccharide with a relatively lower melting point than the drug and the diluent, which comprises (a) the process whereby tablet starting materials including a drug, a diluent, and a saccharide with a relatively lower melting point than the drug and the diluent are molded under the low pressure necessary for retaining the shape of a tablet, (b) the process whereby the molded product obtained in process (a) is heated to at least the temperature at which this saccharide with a low melting point will melt, and (c) the process whereby the molded product obtained in process (b) is cooled to at least the temperature at which the molten saccharide with a low melting point solidifies.
