Embodiment 1
[0042] Embodiment 1: The freeze-dried powder injection of trans-dextrooxaliplatin is made from the following components:
[0043] Trans-D-oxaliplatin 50mg, glycine 120mg, the optical purity of oxaliplatin is 100%.
[0044] Preparation:
[0045] (1) Dissolve 50mg of trans-D-oxaliplatin with an optical purity of 100% and 120mg of glycine in 10ml of water for injection, sterilize and filter, divide into 25mL glass bottles, and half add lyophilized rubber stoppers;
[0046](2) Put the packaged liquid medicine bottle on the shelf in the freeze-drying box for pre-freezing; first cool down the temperature of the plate layer to 5°C, keep it for 2 hours, and then quickly cool it down to -50°C within 60 minutes, After pre-freezing for 6 hours, carry out sublimation drying;
[0047] (3) When the vacuum degree in the drying oven reaches below 10Pa, the temperature of the shelf is slowly raised to 0°C in 120 minutes for sublimation drying, and the vacuum is controlled below 30Pa during t...
Embodiment 2
[0050] Embodiment 2: The freeze-dried powder injection of trans-dextro-oxaliplatin is made from the following components:
[0051] Trans-D-oxaliplatin 50mg, trehalose 135mg, the optical purity of trans-D-oxaliplatin is 99.99%.
[0052] Preparation:
[0053] (1) Dissolve 50mg of trans-D-oxaliplatin with an optical purity of 99.99% and 135mg of trehalose in 10ml of water for injection, sterilize and filter, divide into 25mL glass bottles, and half add lyophilized rubber stoppers ;
[0054] (2) Put the packaged liquid medicine bottle on the shelf in the freeze-drying box for pre-freezing: first cool down the temperature of the plate layer to 0°C, keep it for 2 hours, and then quickly cool it down to -60°C within 60 minutes , after pre-freezing for 4 hours, carry out sublimation drying;
[0055] (3) When the vacuum degree in the drying oven reaches below 30Pa, the temperature of the shelf is slowly raised to 0°C in 120 minutes for sublimation drying, and the vacuum is controlle...
experiment example 1
[0058] Experimental example 1, resolubility test
[0059] The trans-dex-oxaliplatin freeze-dried powder injection obtained in Examples 1 and 2 was detected, and the results are shown in Table 1 below:
[0060] Table 1. Reconstitution of lyophilized powder injection
[0061]
[0062] The above data show that the trans-D-oxaliplatin freeze-dried powder injection with high optical purity provided by the present invention has good reconstitution properties.
