Pharmacodynamics and pharmacokinetics

Metformin is an biguanidefrom hypoglycemic effectable to lower concentration glucose in the blood plasma. However, it does not stimulate the production of insulintherefore does not cause hypoglycemia. During treatment, peripheral receptors become more sensitive to insulin, and glucose utilization by cells increases. Liver glucose synthesis is reduced due to inhibition of glycogenolysis and gluconeogenesis. Delayed absorption of glucose in the digestive tract.

The active component of the drug stimulates the production of glycogen by acting on glycogen synthase. Increases the transport capacity of any membrane glucose transporters.

In the treatment metformin patients retain body weight or notice a moderate decrease. The substance has a beneficial effect on lipid metabolism: decreasing the level of total cholesterol triglycerides and LDL.

Long-acting tablets are characterized by delayed absorption. Therefore, the therapeutic effect persists for at least 7 hours. The absorption of the drug does not depend on food and does not cause cumulation. Insignificant binding to plasma proteins is noted. Metabolism occurs without the formation of metabolites. Excretion of components occurs in an unchanged form with the help of the kidneys.

When symptoms of lactic acidosis are manifested, it is necessary to immediately stop taking the medicine, in a hospital, determine the concentration of lactate, with a clarification of the diagnosis. The effectiveness of the procedure for removing lactate and metformin from the body using hemodialysis is noted. Concomitant symptomatic therapy is also performed.

Combinations with amiloride, digoxin, morphine, procainamide, quinidine, quinine, ranitidine, triamteren, trimethoprimand vancomycin, which are secreted in the renal tubules, enter into competition with metformin for tubular transport, which increases its concentration.
