Embodiment 1

[0023] Take 400ml of absolute ethanol and 300ml of normal saline and stir, then add 300ml of polyethylene glycol 400, and stir evenly; then, add 40g of Tween 80, stir evenly, add 0.25g of activated carbon for needles, heat at 35°C for adsorption, coarse filter to remove carbon , with a pH value of 3, filtered through a 0.22 μm microporous membrane, potted, and sterilized at 115°C for 30 minutes as a solvent; the glass infusion bottle was washed with potassium dichromate sulfuric acid solution, dried at 260°C for 25 minutes, and Base the rubber stopper for sterilization; take 3 g of paclitaxel and add it to the solvent for dissolving, filter it for sterilization, and pour it into a glass infusion bottle to seal it under aseptic purification conditions to prepare paclitaxel injection containing 150 mg of paclitaxel per 50 ml.

Embodiment 2

[0025] Take 400ml of absolute ethanol and 300ml of normal saline and stir, then add 300ml of polyethylene glycol 400, and stir evenly; then, add 30g of Tween 80, stir evenly, add 0.3g of activated carbon for needles, heat at 40°C for adsorption, coarse filter to remove carbon , with a pH value of 5, filtered through a 0.3 μm microporous membrane, potted, and sterilized at 125°C for 20 minutes as a solvent; the glass infusion bottle was washed with potassium dichromate sulfuric acid solution, dried at 230°C for 35 minutes, and Base the rubber stopper for sterilization; take 2 g of paclitaxel and add it to the solvent to dissolve, sterilize and filter, pour it into a glass infusion bottle and seal it under aseptic purification conditions, and prepare a paclitaxel injection containing 100 mg of paclitaxel per 50 ml.

Embodiment 3

[0027] Take 300ml of absolute ethanol and 400ml of normal saline and stir, then add 300ml of polyethylene glycol 400, and stir evenly; then, add 20g of Tween 80, stir evenly, add 0.5g of activated carbon for needles, heat at 40°C for adsorption, coarse filter to remove carbon , with a pH value of 5, filtered through a 0.4 μm microporous membrane, potted, and sterilized at 100°C for 35 minutes as a solvent; the glass infusion bottle was washed with potassium dichromate sulfuric acid solution, dried at 250°C for 30 minutes, and Base the rubber stopper for sterilization; take 0.6 g of paclitaxel and add it to dissolve in the solvent, filter it for sterilization, and pour it into a glass infusion bottle to seal it under aseptic purification conditions to prepare a paclitaxel injection containing 30 mg of paclitaxel per 50 ml.

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 isadded 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.

Description
