In the sixties of the twentieth century, biochemists defined the basic concept of the mechanism of the development of type 2 diabetes - obesity is accompanied by insulin resistance, which in turn causes hyperinsulinemia, and as a result leads to an absolute deficiency of insulin and hyperglycemia.

Insulin resistance of muscle, adipose tissue and hepatic cells is genetically determined, the main component of the origin of type 2 diabetes mellitus, closely associated with such pathological conditions as dyspidemia, obesity, hypertension.

In clinical practice, for more than half a century, a biguanide class preparation( Glucophage( metformin hydrochloride)) has been used for the treatment of type 2 diabetes.

Form release, pharmacological action

The preparation is produced in the form of round, biconvex tablets of white color, coated with a film membrane. Each Glucophage tablet contains an active ingredient - metformin hydrochloride( 500, 850, 1000 mg) and ancillary elements - magnesium stearate,

hypromellose and povidone.

Long-acting Glucophage Long contains 750 mg of metformin hydrochloride and additional components - magnesium stearate, hypromellose and povidone.

Metformin is an active substance that has a pronounced hypoglycemic property that develops only in conditions of hypoglycemia, that is, in people with normal blood glucose levels. The substance has no hypoglycemic effect.

The mechanism of action of Glucophage and Glucophage Long is based on the ability to inhibit glycogenolysis and gluconeogenesis, reduce glucose absorption in the gastrointestinal tract and increase insulin sensitivity. The drug contributes to an effective reduction in the production of glucose in the liver, actively reduces its concentration in the blood plasma and stimulates the utilization of glucose in the muscles.

Metformin, in addition to pronounced antihyperglycemic action, has the effect of improving lipid metabolism, reducing the level of cholesterol, triglycerides and lipoproteins. Also, it is able to reduce and stabilize the weight, therefore, specialists sometimes appoint Glucophage for weight loss.

The drug is adsorbed in the gastrointestinal tract, the peak concentration in the plasma is reached after 2-2,5 hours after administration. The time of maximum plasma concentration of metformin in Glucophage Long is 7 hours. This property of the drug is used to reduce possible side effects.

When ingested, the absolute bioavailability reaches 50-60%.The substance in the body is practically not metabolized and is mainly excreted by the kidneys, only a small percentage - by the intestine. There are reviews of Glucophage, confirming its ability to reduce appetite.
