It is practically not absorbed in the intestine. After taking the drug at a dose of 100 mg twice a day for three consecutive days, the plasma concentration of mebendazole and its metabolite (2-amino derivative) does not exceed 0.03 mcg / ml and 0.09 mcg / ml, respectively. The bond with plasma proteins is 90%. It is unevenly distributed among organs, accumulates in adipose tissue, liver, larvae, helminths. In the liver, it is metabolized to a 2-amino derivative that does not have anthelmintic activity. The half-life. 2.5-5.5 h. More than 90% of the dose is removed through the intestine unchanged.

Causing irreversible disruption of glucose utilization, depletes glycogen reserves in helminth tissues, prevents the synthesis of cellular tubulin, and also inhibits the synthesis of adenosine triphosphate (ATP).
