The invention belongs to the technical field of pharmaceutical preparations and particularly relates to
cefadroxil dispersible tablets and a preparation method therefor. A prescription for the
cefadroxil dispersible tablets per 10,000 tablets comprises the following ingredients by weight: 5,000g of
cefadroxil, 1,000g-1,300g of filler, 500g-800g of disintegrant and 20g-100g of
magnesium stearate. The preparation method comprises the steps of weighing the cefadroxil, the filler and the disintegrant according to prescription amounts, carrying out uniform mixing, then, adding the
lubricant, i.e.,
magnesium stearate, carrying out uniform mixing, then, carrying out tabletting by a tabletting
machine, thereby obtaining the cefadroxil dispersible tablets. The cefadroxil dispersible tablets prepared by the preparation method are uniform in unit-time
drug release, readily available in raw materials and controllable in quality. According to the preparation method, the cefadroxil dispersible tablets are produced by employing a mixed-
powder direct-tabletting process, the process is simple, the quality is stable, the operation is easy, the method is applicable to large-scale production, and therisk of degradation of the cefadroxil is avoided.
