.Metformin hydrochloride is a biguanide oral hypoglycemic agents , also known as metformin hydrochloride , Glucophage , United Dikang , hypoglycemic effect is weaker than phenformin , the main role is to reduce the A cell glucagon secretion , promote the conversion of glucose to glycogen , has not stimulate insulin secretion from pancreatic β- cell characteristics .
Hypoglycemic mechanism is as follows:
1 . Increase the sensitivity of peripheral tissues to insulin , increased insulin -mediated glucose utilization .
2 glucose utilization increase in non -insulin-dependent tissues such as brain, blood cells , kidney medulla , intestine, skin and so on.
3 hepatic gluconeogenesis inhibition effect, reducing hepatic glucose output .
4 inhibited intestinal cell uptake of glucose .
5 Inhibition of cholesterol biosynthesis and storage, reduce blood triglyceride and total cholesterol levels.
Clinically metformin hydrochloride for the treatment of simple diet control are not satisfied with type Ⅱ diabetes patients, especially with obesity and hyperinsulinemia who use the drug not only hypoglycemic effect, may also have to reduce the weight and hyperinsulinemia effect. For some sulfonylureas may be effective in patients with poor efficacy , such as the sulfonylureas , intestinal glucosidase inhibitors or thiazolidinediones , TZDs hypoglycemic drugs , were better than the results alone . Can also be used in patients with insulin therapy to reduce the amount of insulin
