Problems solved by technology

Compared with aqueous solution, freeze-dried powder has the following disadvantages: 1. High production cost; 2. Non-terminal sterilization, low level of sterility assurance, complex process, high requirements for production environment and equipment; 3. Inconvenient to use, need to inject solution to dissolve , increasing the chance of contamination
[0004] At present, the irinotecan hydrochloride injections produced by domestic and foreign manufacturers all contain a considerable amount of sorbitol as a stabilizer in their prescriptions, which not only increases the cost, but also increases the risk of medication for patients.

Abstract

The invention discloses an irinotecan hydrochloride liquor type injection and a preparation method thereof, which is characterized in that the injection contains buffer salt, no stabilizing agent, i.e. sorbierite. In addition, the invention also discloses a preparation method of the irinotecan hydrochloride injection. The irinotecan hydrochloride injection obtained by utilizing the method has stable quality, pharmacy safety and low production cost.

Description

Technical field [0001] The invention relates to the field of irinotecan hydrochloride preparations, in particular to an irinotecan hydrochloride injection and a preparation method thereof. Background technique [0002] Irinotecan hydrochloride (Irinotecan, CPT-11) is a water-soluble camptothecin derivative jointly developed by Daiichi Seiyaku and YakultHonsha in Japan. The chemical name is (+)-(4S)-4, 11-diethyl- 4-Hydroxy-9[(4-piperidinylpiperidine)carbonyl]-1H-pyrano[3′,4′:6,7]indolazine[1,2-b]quinoline-3,14 -(4H, 12H)-Diketone hydrochloride trihydrate. Irinotecan hydrochloride is a modified natural camptothecin derivative. It is an anti-cancer drug with definite curative effect and less toxic and side effects. It is a specific drug for advanced colorectal cancer. For patients who have failed chemotherapy with 5-fluorouracil, this product can be used as a second-line treatment. It is also effective for small cell and non-small cell lung cancer, cervical cancer and ovarian can...
