Description

technical field [0001] The invention relates to an anti-diabetic pharmaceutical composition, more specifically to a pharmaceutical composition comprising a DPP-4 inhibitor and metformin hydrochloride and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Diabetes mellitus is a chronic disease with multiple pathological manifestations, accompanied by disorders of lipid metabolism, circulation and glucose metabolism. As a result, diabetes is prone to develop multiple complications in many cases. Therefore, it is necessary to select the drug suitable for the dominant disease stage for each individual's condition. However, this option is often difficult to implement clinically, because single use of a drug cannot produce sufficient efficacy in certain disease states, and increasing the dose or taking the drug for a long time will bring various side effects such as side effects. question. [0003] Both d...
