Embodiment 1
[0033] Flurbiprofen axetil fat emulsion injection production technology, comprises the following steps:
[0034] S1. Water phase preparation: Glycerin and disodium hydrogen phosphate are prepared into water phase with water for injection, citric acid is used to adjust the pH value of the water phase to 9-10, and the temperature of the water phase is controlled at 70-80°C;
[0035] specifically:
[0036] Add about 25,000 ml of water for injection into the glycerin tank, and put in 1.989Kg of glycerin (for injection) and disodium hydrogen phosphate (Na 2 HPO 4 ) 25.2g and an appropriate amount of citric acid. Close the feeding port, evacuate to below -0.04Mpa, and then fill with nitrogen, repeat this process for more than 4 times, and finally maintain positive pressure with nitrogen. Turn on the glycerin pump, filter the glycerin solution in the glycerin tank to the water phase tank through a cartridge filter (polypropylene filter element, 0.22um), after the glycerin solution...
Embodiment 2
[0054] This embodiment is based on embodiment 1, and the difference with embodiment 1 is:
[0055] In step S1, the temperature of the water phase is controlled at 60-70°C, in step S2, the temperature of the oil phase is controlled at 75-80°C, and the temperature of the emulsion is controlled at 60-70°C.
[0056] The flurbiprofen axetil fat emulsion injection prepared in the present embodiment is detected in particle size and pH value, and the detection results are:
[0057] The particle size is 160-220nm, and the pH value is 6.3-6.6.
[0058] By the data of embodiment 1 and embodiment 2 as can be known:
[0059] The emulsions prepared by the process of the present invention are all weakly acidic, and the human body needs intravenous injection, and the consistency of the emulsion is good (narrow particle size range); under the premise of the temperature control range of the present invention, the lower temperature will not affect The consistency of the emulsion, but the avera...
