Problems solved by technology

The preparation process of this method is cumbersome, the crystallization time is long, and the configuration cycle is correspondingly prolonged
In addition, the application also discloses that the stability of the insulin lispro suspension preparation using disodium hydrogen phosphate as a buffer is not as good as that of TRIP (2-amino-2-hydroxymethyl-1,3-propanediol and its pharmaceutically accepted salts) ) as a suspension formulation of a buffer

Abstract

The invention provides a preparation method of an insulin lispro-protamine sulfate preparation. The insulin lispro-protamine sulfate preparation contains the following ingredients in concentration: 3.47mg / ml of insulin lispro, 0.095mg / ml to 0.28mg / ml of protamine sulfate, 0.025mg / ml to 0.05mg / ml of zinc, 0.5mg / ml to 1.0mg / ml of phenol, 1.5mg / ml to 2.5mg / ml of m-cresol, 16mg / ml of glycerine and 2mg / ml to 4mg / ml of disodium hydrogen phosphate. The preparation method comprises the steps of carrying out solution mixing on an acidic solution of insulin lispro and an alkaline solution of protamine sulfate, then, carrying out crystallization, adding an m-cresol and glycerine solution into completely-crystallized crystalline liquid, and carrying out uniform mixing, thereby obtaining the insulin lispro-protamine sulfate preparation. According to the preparation method, the consumed time is short, and the obtained product is stable in quality.

Description

technical field [0001] The invention belongs to the fields of biomedicine and pharmacy, and in particular relates to a preparation method of an insulin lispro protamine sulfate preparation and the prepared insulin lispro protamine sulfate preparation. Background technique [0002] Diabetes mellitus (Diabetes Mellitus) is a chronic comprehensive disease mainly caused by the disorder of glucose metabolism caused by absolute or relative insulin deficiency or decreased sensitivity of target cells to insulin, which seriously affects the health and quality of life of patients. With the improvement of economic level and material conditions, the incidence of diabetes continues to rise. According to the statistics of the International Diabetes Federation (IDF), there were about 100 million people with diabetes worldwide in the 1990s, and the number had rapidly increased to 246 million in 2007. It is estimated that there were about 415 million diabetics in the world in 2015, and the ...
