Pharmacological properties
Pharmacodynamics
Mebendazole is a broad-spectrum anthelmintic drug, especially effective for trichocephalosis and enterobiasis. It inhibits the assembly of microtubules by binding to nematodes with β-tubulin, causing a decrease in the rate of glucose transport and uncoupling of oxidative phosphorylation. The drug inhibits the activity of mitochondrial fumarate reductase and leads to a decrease in mobility and further death of helminths due to adenosine triphosphate deficiency.
Pharmacokinetics
Mebendazole is practically not absorbed in the intestines. Its half-life is 2.5-5.5 hours. The active substance of the drug binds to plasma proteins by 90% and is unevenly distributed throughout the organs, which causes the accumulation of Mebendazole in the larvae of helminths, liver, adipose tissue. In the liver, the drug is metabolized to form a 2-amino derivative of mebendazole. More than 90% of the dose taken is excreted in the feces unchanged. The absorbed part (approximately 5-10%) is excreted through the kidneys. With hepatic insufficiency, the half-life increases to 35 hours.
