Problems solved by technology

[0005] CN200910127355.6 discloses a capsule preparation of S-1 and its preparation method. This invention improves the stability of S-1, but the water solubility of the drug has not been improved, which affects the dissolution rate of S-1 in the stomach , so that its bioavailability is limited, thereby affecting the efficacy
At the same time, for traditional oral administration capsules, a large number of patients, especially the elderly and children, have poor compliance with swallowing difficulties.
[0006] CN200410075803.X invented a prescription and preparation process of S-1 orally disintegrating tablets, which can mask the bad bitterness of the drug, but the stability and water solubility of the drug have not been improved

Abstract

The invention belongs to the technical field of medicaments, and relates to TS-1 granules for treating advanced gastric cancer and a preparation method thereof. The method comprises the following steps of: preparing active medicaments tegafur, gimeracil and potassium oxonate into a cyclodextrin inclusion compound; and sieving the inclusion compound, uniformly mixing the sieved inclusion compound and pharmaceutically acceptable auxiliary materials and performing wet granulation or dry granulation to prepare the granules. The granules have the advantages of increasing the water solubility and stability of the medicaments, covering the bitter taste of the tegafur, prolonging the action time, improving the medication compliance of patients with cancer, greatly improving the bioavailability of the medicaments and reducing the toxic or side effect of the medicaments.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a granule of S-1, a drug for treating advanced gastric cancer, 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 duration is longer than that of intravenous ad...
