It is characterized in that, described lyophilization, the vial that fill is good is put into the freeze drying box being cooled to 5 DEG C, it is cooled to rapidly-40 DEG C, freezing 3 hours of insulation, then evacuation, it is warming up to-5 DEG C in 3 hours, the time maintaining-5 DEG C was 10 hours, was warming up to 40 DEG C at 3 hours, and the time maintaining 40 DEG C is 6 hours.
Above-mentioned steps 1) described in course of dissolution in, first sodium hydroxide and Ceftaroline Fosamil are joined in the water for injection of 10 �� 5 DEG C after fully dissolving, add mannitol, both are uniformly distributed in the solution, finally obtain lyophilisation product redissolution type good.
Above-mentioned steps 2) in the 0.1%g/ml that consumption is joined liquor capacity of activated carbon.
The impact on product of the consumption of activated carbon, if activated carbon dosage is too many, the active component in adsorbent solution can be caused, the productivity making its product reduces, if activated carbon dosage is very little, it is impossible to decoloured by solution completely, pyrogen removal, the removal of impurity, and then affect the performances such as the quality of product, purity, so the selection of the consumption of activated carbon should be considered.
The inventors discovered that, in CPT ester solution, add the activated carbon of 0.1%g/ml, now principal agent Ceftaroline Fosamil be there's almost no adsorption by activated carbon, after filtration, solution colour is colorless cleared solution, and after activated carbon adsorption, Ceftaroline Fosamil carries out having related substance to detect, and wherein impurity is almost without change, bacterial endotoxin is qualified, refers to experimental example 1.
Above-mentioned steps 2) in, after adding activated carbon, stir 15 minutes.

After Pharmaceutical freeze, starting vacuum machine and be evacuated to 15Pa, close fridge, be warming up to-5 DEG C to medicine in 3 hours, the time maintaining-5 DEG C is 10 hours.
The choice relation of sublimation temperature, to the speed of distillation, selects temperature to-5 DEG C, during distillation, upper materials takes the lead in drying, if the rising of its temperature is too fast, it is possible to reach disintegrate temperature, porous matrix rigidity reduces, coming off occurs in granule in drying layer, and can close the microporous filter membrane of drying nest, stops the carrying out of distillation, rate of sublimation is made to slow down, even make underclad portion slightly atrophy, affect the content of the residual moisture of goods, cause that solubility, stability and clarity are deteriorated simultaneously.
Pressure during distillation is 15Pa, rather than lower, although this is because pressure is low is conducive to the life of ice in product, but due to pressure too low time, heat transfer is unfavorable, and product not easily obtains heat, and rate of sublimation reduces on the contrary. But, when pressure is too high, in product, the rate of sublimation of ice slows down, and product caloric receptivity will reduce, and then the temperature of product self rises, when higher than temperature of eutectic point, product will melt, and causes lyophilizing failure, therefore, being 15Pa by pressure set, the transmission being both beneficial to heat is conducive to the carrying out of distillation.
During drying going out the process of Bound moisture, after sublimation drying, also remaining part absorption water and Bound moisture, these water are not frozen, can not remove in primary drying. Temperature was warming up to 40 DEG C at 3 hours by the present invention after sublimation drying, and the time maintaining 40 DEG C is 6 hours, and the freeze-drying prods moisture of gained is lower than 3%, as well known to those skilled in the art, and the moisture of freeze-drying prods is more low, and its stability is more good.
