After Metforminum is accepted orally, the greatest concentration is noted in plasma 2,5 hours later. People who receive medicine in the maximum doses the largest content of active component in plasma had no higher than 4 mkg/ml.

Absorption of active component stops 6 hours later after reception. As a result, plasma concentration goes down. If the patient accepts the recommended drug doses, then in 1-2 days in plasma stable constant concentration of active ingredient in border of 1 mkg/ml and is noted less.

If to take medicine in the course of food, then absorption of active component decreases. It Kumulirutsya, generally in walls of a digestive tube.

Time of its semi-removal is equal to about 6,5 hours. Bioavailability level at healthy people makes 50-60%. With proteins of plasma its communication insignificant. Through kidneys there are about 20-30% of a dose.
