Definitions
- This application relates to the technical field of hypoglycemic preparations, in particular to a pharmaceutical composition for treating diabetes and a preparation method thereof.
- Diabetes is divided into many types, but nearly 90% of the affected population are type 2 diabetes patients. According to relevant reports, about 6% of the world’s 20-79 age group of adults suffer from type 2 diabetes. According to relevant statistics, the number of people suffering from type 2 diabetes will continue to increase. By 2025, the number of people suffering from the disease is expected to reach 380 million, which will account for 7.1 of all adults in the 20-79 age range in the world. %.
- type 2 diabetes As a chronic metabolic disease, type 2 diabetes is characterized by high blood sugar, which is mainly caused by relatively insufficient insulin secretion and insulin resistance. In addition, a significant feature of type 2 diabetes is that its condition is irreversible, which eventually causes many 2 Patients with type 1 diabetes develop into type 1 diabetes patients. At present, there is no clinically effective drug that can cure type 2 diabetes. In the early stage of the disease, long-term strict lifestyle control such as diet control and physical exercise is often required to reduce blood sugar and increase insulin. Resistance is improved to achieve the goal of controlling the development of type 2 diabetes.
- Sodium-glucose cotransporter 2 (SGLT2) inhibitors include dapagliflozin, repaggliflozin, sepagliflozin, apagliflozin, etc., among which dapagliflozin is the first approved and marketed in Europe The effect of SGLT2 inhibitors in the treatment of diabetes has been initially confirmed by clinical studies.
- Tianagliflozin (Tianagliflozin) is a new SGLT2 inhibitor with 5 chiral centers and its chemical name is: (IS)-1,5-dehydrate-6-deoxy-1-C-[4-chloro- 3-[(4-Ethoxyphenyl)methyl]phenyl]-D-glucitol, molecular formula: C 21 H 25 ClO 5 , molecular weight: 392.87, structural formula:
- the SGLT2 inhibitor dapagliflozin (dapagliflozin) and extended-release metformin hydrochloride have been combined.
- the drug is used as an adjuvant drug, combined with diet and exercise. Control blood sugar.
- EMEA approved Novartis's vildagliptin/metformin hydrochloride compound tablet on November 14, 2007, to treat type 2 diabetes, for the treatment of patients who cannot effectively control blood sugar with the maximum tolerated dose of metformin.
- the compound tablet The dosage specification of the drug is vildagliptin/guanidine diformate hydrochloride 50mg/850mg/1000mg.
- the application provides a pharmaceutical composition for treating diabetes and a preparation method thereof.
- the pharmaceutical composition has stable curative effect, good effect on treating type 2 diabetes, good patient compliance, and can prevent recurrence, which meets the needs of modern people.
- the present application provides a pharmaceutical composition for the treatment of diabetes.
