Metformin is an antidiabetic drug that promotes better glucose absorption. The World Health Organization has included this drug in the list of essential medicines.
pharmachologic effect
The drug belongs to the biguanide group, the active ingredient is dimethyl biguanide. It is obtained from the plant Galega officinalis. Metformin interferes with the synthesis of glucose by the liver (the process of gluconeogenesis), thereby lowering blood sugar levels. In parallel with this, the drug increases the sensitivity of insulin receptors, improving its absorption, promotes better oxidation of fatty acids, increases the peripheral utilization of glucose, and reduces its absorption from the digestive tract.
The agent helps to reduce thyroid-stimulating hormone in the blood serum, lowering the level of cholesterol and low-density lipoproteins, thereby preventing pathological changes in blood vessels. Normalizes blood clotting, improving its rheological properties, thereby helping to reduce the risk of thrombus formation.
Reviews of Metformin from endocrinologists confirm the information that it contributes to weight loss in obesity.
Release form
Available in the form of coated tablets for oral administration, 30, 60 and 120 tablets in a blister. The tablets contain 500 or 850 mg of dimethyl biguanide. In addition to the main active ingredient, the tablet contains starch, magnesium stearate, talc.

Indications for use
The use of Metformin is indicated in the treatment of type 2 diabetes with preserved renal function, as well as in a pre-diabetic state. A direct indication for use is type 2 diabetes, accompanied by obesity.
It is also used as part of complex therapy in the treatment of abdominal-visceral obesity.
During its use in clinical practice, reviews of Metformin were so positive that after conducting clinical studies that confirmed them, in 2007 the drug was recommended for use in pediatric practice for the treatment of type 1 diabetes, as an adjunct to insulin therapy.
Instructions for the use of Metformin
Metformin tablets are taken strictly after meals with plenty of water. The first and initial doses are 1000 mg per day, within 1-2 weeks the dose is gradually increased, its value is adjusted under the control of laboratory data on the level of glucose in the blood. The maximum allowable dose is 3000 mg per day. The daily dose can be used in one dose, but at the beginning of therapy, during the adaptation period, it is recommended to divide it into 2-3 doses, which helps to reduce the side effect of the drug on the gastrointestinal tract.
The highest concentration of the drug in the blood plasma is observed 2.5 hours after ingestion, after 6 hours it begins to decrease. After 1-2 days of regular intake, a constant concentration of the drug in the blood is established, according to reviews, Metformin begins to have a noticeable effect two weeks after the start of administration.
With the combined use of Metformin and insulin, medical supervision is necessary, with high doses of insulin - in a hospital.
Side effects
When used as directed, Metformin is generally well tolerated by patients, rarely causing side effects. If there are any, then, as a rule, they are associated either with an individual drug intolerance, or with interaction with other drugs, or with excess dosage.
According to reviews, Metformin most often causes disorders of the digestive system, manifested in the form of dyspepsia in one form or another, as one of the symptoms of lactic acidosis. Usually, such signs are observed at the beginning of the course of drug treatment, and after a period of adaptation they pass. According to the instructions, Metformin in this case must be used in a reduced dosage; in case of severe lactic acidosis, the drug is canceled.
With prolonged use, Metformin contributes to the disruption of the metabolism of vitamin B12 (cyanocobalamin), preventing its absorption in the intestine, which can cause symptoms of B12-deficiency anemia. This condition requires drug correction.
