The invention discloses high-stability
capecitabine tablets and a preparation method thereof. The tablets contain L-
methionine,
polacrilin potassium and other auxiliary materials which are acceptable in
pharmacy and low in hygroscopicity. The tables are prepared through the following steps: 1, weighing the L-
methionine, and dissolving the L-
methionine in the water for standby application; 2, smashing and sieving the
capecitabine, weighing and mixing the
capecitabine, the
polacrilin potassium, filling agents and adhesion agents uniformly, adding an L-methionine
aqueous solution for prilling, and conducting sieving,
drying and granulating; 3, mixing dry particles and lubricating agents uniformly, and obtaining the capecitabine tablets through tabletting. The prepared tablets are small in related substance, good in stability, fast to dissolve, simple in preparation process and suitable for industrialized
mass production.
