Abstract

The invention relates to a compound repaglinide-metformin hydrochloride solid quick-release preparation and a preparation method and an application thereof, and belongs to the technical field of medicines. A quick-release tablet is prepared from repaglinide and metformin hydrochloride which are taken as medicinal active components, and suitable medicinal auxiliary materials, and the problems of quick dissolution-out of the indissolvable medicine, namely, repaglinide and the stability of the repaglinide in a tablet placement process are solved. The preparation method comprises the following steps of: respectively granulating the repaglinide and the metformin hydrochloride by selecting the suitable medicinal auxiliary materials; mixing, and then pressing into tablets, or filling into capsules. The prepared compound preparation has a synergetic effect on controlling blood sugar and improving the curative effect and is convenient for patients to take.

Description

technical field [0001] The invention belongs to the technical field of medicine, in particular to a solid compound immediate-release preparation of repaglinide and metformin hydrochloride, a preparation method and application thereof. Background technique [0002] Diabetes is a combination of sugar, protein, fat, water, and A series of metabolic disorder syndromes such as electrolytes are clinically characterized by high blood sugar. Once the blood sugar is not well controlled, it will cause complications and lead to failure of the kidneys, eyes, feet and other parts. According to the pathological features displayed by diabetic patients, it is mainly divided into type 1 diabetes and type 2 diabetes. Type 1 diabetes is insulin-dependent, due to the lack of insulin secretion, it relies on exogenous insulin supplementation to maintain life. Type 2 diabetes is non-insulin-dependent, characterized by the body's own ability to produce insulin, but the cells cannot respond to it,...
