Abstract

The invention relates to a paclitaxel injection and a preparation method of the injection: (1) 200 to 400ml of absolute alcohol and 200 to 400ml of normal saline are taken to be stirred, and 150 to 400ml of polyethylene glycol 400 is added to be evenly mixed; (2) 20 to 40g of tween-80 is added in to the mixture of (1) to be evenly mixed, and then 0.2 to 0.5g of active carbon used for injection is added to be heated by 35 to 40 DEG C, and raw filtering is carried out and the PH value is controlled to be between 3 to 5; filtering is done and filling and sealing process is carried out; sterilization is carried out for 20 to 35 minutes at the temperature of 100 to 125 DEG C; (3) a transfusion bottle is washed and then is dried for 25 to 35 minutes the temperature of 230 to 260 DEG C, and butyl rubber plug is sterilized; (4) 0.6 to 3g of paclitaxel is taken to be added into the mixture of (2) for dissolving, and then sterilization and filtering are done; and then the solution is filled into the transfusion bottle in the sterilized environment; finally, the bottle is sealed to get the finished product. The invention can prepare safe and reliable paclitaxel injection, by adopting the method of preparing menstruum firstly and paclitaxel solution secondly, the quality of the injection is guaranteed.
