The present invention relates to a furazolidone tablet preparation method, which is performed according to the following steps: taking furazolidone, a binder and a solubilizer, screening, respectively screening a lubricant and a flow aid with a 80-120 mesh sieve, adding water or an alcohol to the partial binder having the content of more than or equal to 28% of the total amount of the binder and the partial solubilizer having the content of more than or equal to 14% of the total amount of the solubilizer to prepare a binder solution with a mass concentration of 1-30%, uniformly mixing the remaining binder and the remaining solubilizer, uniformly mixing with the furazolidone according to an equivalent gradual increase method, adding the binder solution to prepare a soft material, carrying out 12-30 mesh pelletization, drying at a temperature of less than 70 DEG C, carrying out 12-30 mesh granulating, adding a lubricant and a flow aid, uniformly mixing, and tabletting to obtain the finished product. According to the present invention, the reasonable process operation sequence is adopted, the part of the solubilizer is adopted to increase furazolidone hydrophilicity, and the part of the solubilizer is adopted to promote furazolidone self-emulsifying and increase solubility in water so as to improve a dissolution rate and increase bioavailability.
