The invention relates to a preparation method of an analgin tablet. The method comprises the following steps: respectively passing analgin, a filler, an adhesive, a disintegrant and a lubricant through a 60-100-mesh screen, adding water or 50-95 wt% ethanol into 40-100 wt% of the adhesive to prepare a 1-30 wt% adhesive solution, evenly mixing the rest of adhesive with the filler, analgin and 40-100 wt% of disintegrant, adding the adhesive solution to prepare a soft material, making 12-30-mesh granules, drying at 60-80 DEG C, finishing the 12-30-mesh granules, adding the rest of disintegrant, lubricant and a flow aid, uniformly mixing and tabletting. By adopting the reasonable technological operation sequence, the method is simple and convenient to operate, and suitable for industrial production. The method ensures the stability of analgin and can ensure that all the indexes of the product are acceptable, and related substances of the product are not overproof in the storage period.
