Pharmacokinetic properties

It is rapidly absorbed after oral administration (food intake does not affect the rate of resorption) and is detected in the blood serum after 15 min. Cmax in adults (when taking 150 mg) - 6.6 mg / l is reached after 2.2 h. Cmax in children (with a double dose of 2.5 mg / kg per day) - 8,7–10,1 g / l is determined after 2 hours. Effective concentrations in the blood are maintained for 1 day with a double (with an interval of 12 hours) intake. The equilibrium concentration in the plasma is determined on the 2-4 th day. It penetrates well into the tissues (especially the lungs), the palatine tonsils and the prostate gland, as well as into the cells (especially neutrophilic leukocytes and monocytes, stimulates their phagocytic activity). The binding to plasma proteins is 96%, is saturable and decreases at concentrations above 4 mg / l. It is partially metabolized, more than half of the active substance is excreted unchanged mainly by the intestines and kidneys. T1/2 in adults, after a single dose, it is on average 10.5 hours, in children-20 hours.
