Pharmacological action

Sanoxal - anthelmintic and antiprotozoal agent. Selectively inhibits the polymerization of beta-tubulin, which leads to the destruction of the cytoplasmic microtubules of the cells of the intestinal tract of helminths, changes the course of biochemical processes (inhibits the utilization of glucose), blocks the movement of secretory granules and other organelles in the muscle cells of roundworms, causing their death. Most effective against larval forms of cestodes - Echinococcus granulosus and Taenia solium nematodes - Strongyloides stercolatis.

Pharmacokinetics

Absorption

After oral administration, it is poorly absorbed from the gastrointestinal tract due to poor solubility in water. The drug is rapidly metabolized during the first passage through the liver, therefore, the plasma concentrations of albendazole unchanged are negligible and are not determined. Oral bioavailability is low. However, the simultaneous intake of fatty foods significantly increases the absorption and concentration of albendazole in blood plasma (5 times). Cmax of albendazole sulfoxide is achieved after 2-5 hours.

Distribution of

Plasma protein binding is 70%. Albendazole is well distributed in the body, reaching high concentrations in urine and bile, liver, wall and fluid of parasitic cysts, cerebrospinal fluid.

Metabolism

Albendazole is rapidly metabolized in the liver to form the primary metabolite, albendazole sulfoxide, which also has anthelmintic activity. Albendazole sulfoxide, in turn, is converted to albendazole sulfone (a secondary metabolite) and other oxidized products lacking pharmacological activity.

Albendazole is an inducer of microsomal CYP1A2 enzymes in human liver cells.

Excretion of

T1 / 2 albendazole sulfoxide is 8-12 hours. The drug is excreted in the form of various metabolites in urine and bile, while renal excretion is negligible (less than 1%).

Pharmacokinetics in special clinical cases

Against the background of liver damage, the bioavailability of albendazole increases. Cmaxalbendazole sulfoxide increases by 2 times, and T1 / 2 lengthens.

In patients with impaired renal function, the clearance of albendazole and its metabolites does not change.

Indications

mixed helminthiases

as an aid in the surgical treatment of echinococcosis cysts.

hypersensitivity to the components of the drug

hypersensitivity to other benzimidazole derivatives.

Precautions: inhibition of bone marrow hematopoiesis, liver failure, cirrhosis, cysticercosis involving the retina.

Pregnancy and lactation

Pregnancy is not recommended, unless alternative treatment is possible. Before starting treatment, women of childbearing age are tested for absence of pregnancy. During and within a month after the end of treatment, reliable contraception is mandatory.

Dosage and administration of

The drug is taken orally. The dose is set individually, depending on the type of helminth and the patient's body weight.

With neurocysticercosis and echinococcosis, patients weighing 60 kg and more are prescribed 400 mg 2 times a day, with a body weight of less than 60 kg - at a dose of 15 mg / kg / day in 2 divided doses. The maximum daily dose is 800 mg. The course of treatment for neurocysticercosis is 8-30 days, for echinococcosis - 3 cycles of 28 days with a 14 day break between cycles. With surgical treatment, the duration of drug treatment is 3 courses.

With ascariasis, trichocephalosis, enterobiasis, hookworm adults and children over 3 years old - 400 mg once, if necessary, repeat after 3 weeks.

For giardiasis, adults and children over 3 years old - 400 mg once a day for 3 days.

In case of strongyloidosis and cestodosis, adults and children over 3 years old - 400 mg once a day for 3 days, if necessary, repeat after 3 weeks.

Tablets can be chewed or swallowed whole.

Side effects of the

Digestive system: impaired liver function with a change in functional liver tests (mild or moderate increase in transaminase activity), abdominal pain, nausea, vomiting.
