Abstract

The invention discloses tegafur and gimeracil compound injecta, comprising tegafur, gimeracil, one or several kinds of auxiliaries suitable for injecta, and the balance of water for injection, wherein the tegafur and the gimeracil serve as active constituents, and the tegafur and gimeracil compound injecta is characterized in that the molar ratio of tegafur to gimeracil to oteracil potassium is 1:(0.2-0.4):1.

Description

[0001] The invention relates to an injection, in particular to a compound injection of tegafur and gimester. Background technique [0002] Tegafur (Tegafur, CAS: 17902-23-7) is the prodrug of the antineoplastic drug fluorouracil, which has good therapeutic activity on gastrointestinal tumors, head and neck tumors and breast cancer. In comparison, the toxicity of tegafur is only 1 / 7-1 / 4 of that, while the chemotherapy index has been doubled. The currently commercially available tegafur preparations include tegafur injection (5ml, 0.2g) and oral preparations. Tegafur tablets (50mg), the dosage when using Tegafur alone for treatment is 8000-1200mg / d. Japan's Dapeng Pharmaceutical Co., Ltd. has developed a tegafur compound preparation with the trade name TS-1, which consists of tegafur, gimexast (CAS: 103766-25-2, CDHP for short) and oteracil potassium (CAS : 2207-75-2, also known as potassium oxonate, referred to as OXO) according to the molar ratio of 1:0.4:1 composition, for t...
