Abstract

The invention discloses a paclitaxel pharmaceutical composition and a preparation method thereof. The paclitaxel pharmaceutical composition consists of paclitaxel, a solubilizing agent, a stabilizing agent, an excipient, an acidity regulator and water for injection. A paclitaxel injection is prepared by adopting a freeze drying method. Compared with the prior art, the paclitaxel pharmaceutical composition disclosed by the invention is different in solubilizing process, solubilizing effect and stability. The composition does not contain an organic solvent, thus, the paclitaxel injection has the characteristics of simpler production process, more perfect appearance, shorter freeze drying time and lower equipment requirement. The composition does not contain polyoxyethylenated castor oil, so that the paclitaxel composition has no anaphylactic reaction or hemolysis or irritation. By detection, the paclitaxel injection prepared by adopting the composition and the preparation method disclosed by the invention is high in dissolvability and stability and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a pharmaceutical composition containing paclitaxel and a preparation method thereof. Background technique [0002] Currently, paclitaxel is the preferred antineoplastic drug in hospitals all over the world. It has good anticancer activity and is effective against advanced ovarian cancer, breast cancer, lung cancer, head and neck cancer, esophageal cancer, germ cell tumor, endometrial cancer, lymphoma, Bladder cancer has a certain effect. Combined with other commonly used anti-tumor drugs, the curative effect can be further improved. Its mechanism of action is unique, and its side effects are small. It mainly inhibits the microtubule synthesis of cancer cells, prevents its division and proliferation, and thus exerts its anticancer effect. However, paclitaxel is extremely poor in water solubility. Currently, paclitaxel injections for clinical use are polyoxy...
