Abstract

The invention provides an insulin aspart injection and a preparation method thereof. The injection comprises insulin aspart, alpha-mannatide, a zinc salt and a bacteriostatic agent, wherein the concentration of insulin aspart in the injection ranges from 300 nmol / mL to 1,200 nmol / mL, and the concentration of alpha-mannatide in the injection ranges from 10 nmol / mL to 100 nmol / mL. The insulin aspart injection can improve insulin resistance and improve sensibility of target tissue to insulin, the medicine dose can be reduced to reach expected therapeutic indexes, the toxic and side effects such as hypoglycemia, edema and allergies cannot be caused, the possibility of occurrence of toxicity and medicine resistance is significantly decreased, and the treatment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to an insulin preparation, in particular to an injection containing insulin aspart and a preparation method thereof. Background technique [0002] At present, there are more than 382 million diabetic patients in the world, among which there are about 114 million diabetic patients over the age of 18 in China. Insulin has always been the most effective drug for treating diabetes, but ordinary insulin has many problems such as short action time, large absorption variation, obvious peak action, and high incidence of hypoglycemia, and is increasingly being replaced by insulin analogs (Cao Fenglin, Deng Shaoxiong . Insulin analogs: a new option for diabetes treatment [J]. Medical Review, 2007, 1(13):32-34.). Recombinant insulin aspart, as a fast-acting insulin analogue, was developed using genetic engineering DNA recombination technology (Warren ML, Conway...
