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 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 , the process whereby the molded product obtained in process is heated to at least the temperature at which this saccharide with a low melting point will melt , and the process whereby the molded product obtained in process is cooled to at least the temperature at which the molten saccharide with a low melting point solidifies . the present invention presents a quick - disintegrating tablet in the buccal cavity that can be used for practical purposes in that it has almost the same properties as conventional oral pharmaceutical tablets , that is , it has sufficient tablet strength that it can be used with automatic unit dosing machines , and it is produced by conventional tableting machines , and a manufacturing method thereof . moreover , the present invention presents a quick - disintegrating tablet in the buccal cavity which , in comparison to conventional quick - disintegrating tablets in the buccal cavity , has increased tablet strength and an improved friability without prolonging the disintegration time in the buccal cavity , and a manufacturing method thereof .
