Engeletin is a hypoglycemic drug, used for blood sugar control in patients with type 2 diabetes mellitus who cooperate with diet and exercise control; when metformin alone fails to control blood sugar, it can be used in conjunction with metformin to control blood sugar; when the combined use of metformin and sulfonylureas still fails to control blood sugar, it can be used in conjunction with metformin and sulfonylureas to control blood sugar. Engeletin belongs to SGLT-2 inhibitor (sodium-glucose cotransporter protein 2 inhibitor), clinically belongs to the 2nd line of hypoglycemic drugs. It is usually recommended that if the effect of 1st line hypoglycemic agents such as metformin tablets and acarbose is poor, the application of engeletin tablets can be considered. Engeletin lowers blood glucose by inhibiting the reabsorption of glucose in renal tubules and excreting body sugar through urine. The drug has the side effect of urinary tract infection, and it is recommended to use the drug to drink more water appropriately. It is recommended that diabetic patients taking oral Engeletin Tablets consult an endocrinologist for treatment under the supervision of a doctor.
