Abstract

The invention discloses a stable insulin glargine injection and a preparation method thereof. The stable insulin glargine injection comprises the following components: 100IU / mL of insulin glargine, 10-100 mu g / mL of zinc, 1.5-3.5 mg / mL of metacresol, 0.7-1.8 mg / mL of phenol, 15-20 mg / mL of glycerin, and hydrochloric acid and / or sodium hydroxide and injection water, the pH value is 3.8-4.2. By means of modifying the raw material components and the preparation process of the insulin glargine injection, the stability of the insulin glargine injection is increased and the quality of the preparation is improved, and the insulin glargine injection does not have allergic reactions and the safety is good.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a stable insulin glargine injection and a preparation method thereof. Background technique [0002] Insulin glargine is a long-acting analogue of human insulin, which can form a stable hexamer after subcutaneous injection, increase the binding force between molecules, delay the time of dissolution and absorption, and release a small amount of insulin glargine continuously, so it has predictable , Long-acting, stable, no peak plasma concentration / time characteristics, clinically used in adults and children with type I diabetes and adult type II diabetes. Because of its long-acting nature, insulin glargine only needs to be administered by subcutaneous injection once a day at a fixed time. Type 1 diabetic patients and type 2 diabetic patients whose oral hypoglycemic drugs fail need to use insulin products for life to control blood sugar. Therefore, it is parti...
