Abstract
The invention relates to an insulin glargine injection. The insulin glargine injection is prepared from insulin glargine, glycerin, absolute ethyl alcohol, m-cresol, zinc chloride, benzalkonium chloride, PH regulator and water for injection. The insulin glargine injection is prepared through the following steps that the prescription dose of the insulin glargine is added into an appropriate amount of water for injection, 1 M of a hydrochloric acid solution is added while stirring is conducted, and the insulin glargine is dissolved, wherein the water for injection is precooled to room temperature; the prescription dose of m-cresol, zinc chloride and benzalkonium chloride are added, the mixture is stirred to be uniform, and the solution pH value is adjusted with the PH regulator; the prescription dose of glycerin and absolute ethyl alcohol are added to the scale volume, and the solution is stirred to obtain colorless clear liquid; filtration, filling and light inspection are conducted, and a finished product is obtained. Compared with the prior art, the phenomenon that white points occur in the insulin glargine injection is relieved; meanwhile, the product is stable in quality, and an obvious change does not exit after related substances are unpacked and put at room temperature and the related substances are stored for a long time at 2-8 DEG C.
Description
technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an insulin glargine injection and a preparation method thereof. Background technique [0002] Recombinant glycine-arginineinsulin (recombinantglycine-arginineinsulin) is a long-acting insulin biological product obtained through genetic recombination technology and used to treat type Ⅰ and Ⅱ diabetes. , thus reducing the solubility, forming insulin glargine precipitates, delaying the body's absorption, and prolonging the time of its hypoglycemic effect. Recombinant insulin glargine is a very convenient and effective drug for the treatment of type I and type II diabetes. Recombinant insulin glargine (trade name Lantus) produced by Aventis abroad is different from regular insulin in that the last aspartic acid at the 21st position of the carboxyl end of the A chain is replaced by glycine, and the 30th threonine at the carboxyl end of the B chain is replaced by glycine....
