Abstract

The invention relates to a capsule preparation containing tegafur, Jimeisita and Potassium Oxonate and a preparation method thereof, which is characterized in that the capsule preparation contains tegafu micropill, Jimeisita micropill and Potassium Oxonate micropill, wherein, the micropill is prepared from active drug ingredient, thinner, bond and surface active agent. The micropill is prepared with the extruding-rolling method, the centrifugal-fluidifying method, the pan coating pill floating method and the like, and then, other minor ingredients are added; finally, the capsule is filled. The capsule prepared with the preparation method can be steadily and quickly released in bodies, thus the drug stability is improved. The capsule has high dissolution rate and biological availability, and reduces adverse reaction of medicine.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a pellet capsule preparation containing three kinds of medicines, tegafur, gemesstat and potassium oxonate, and a preparation method thereof. Background technique [0002] Tegafur (FT, FT207) is one of the pyrimidine anticancer drugs. It is the prodrug of 5-fluorouracil (5-FU), and has inhibitory effect on most solid tumors. In the body, it can interfere and block the biosynthesis of DNA, RHA and protein, thereby producing its anticancer effect. Basic medical research and clinical observation have proved that tegafur has less toxic and side effects, higher chemotherapy index, less effect on immunosuppression and related immune organs, and is a safe drug that can be used continuously in clinical practice. This product is absorbed through the gastrointestinal tract after oral administration, and the blood concentration reaches the highest peak within 1-3 hours. The d...
