Abstract

The invention belongs to the technical field of medicine, and particularly relates to a paclitaxel injection and a preparation method thereof. The invention provides a paclitaxel injection having stable quality and low toxicity. The paclitaxel injection provided by the invention contains paclitaxel, polyglycol 15-hydroxystearate, anhydrous alcohol and one or more of citric acid, hydrochloric acid, tartaric acid and malic acid. The preferable formula of the paclitaxel injection comprises 5.4-6.6mg / ml paclitaxel, 5-80(V / V) polyglycol 15-hydroxystearate, 20-95%(V / V) anhydrous alcohol and 0.005-0.02%(mg / ml) citric acid.

Description

technical field [0001] The invention belongs to the technical field of medicine, specifically, the invention mainly relates to a paclitaxel injection, and the invention also provides a preparation method thereof. Background technique [0002] Taxol (Paolitaxel, trade name Taxol)) is a diterpenoid component with a unique structure isolated from Taxus brevifolia, and its skeleton is named taxane. Because of its unique pharmacological action and curative effect, it has been paid much attention clinically. On December 29, 1992, the US FDA officially approved paclitaxel as a new anti-tumor drug for the treatment of advanced ovarian cancer. Brode, the director of the American Cancer Society, praised paclitaxel as the most important new anti-tumor drug discovered in the past 15 years. . Since then, people have made great progress in the research on its pharmacological application and drug sources. At present, this product is clinically used for first-line and second-line treatme...
