PHARMACOLOGY

Albendazole is a broad spectrum anthelmintic. Albendazole exhibits vermicidal, ovicidal and larvicidal activities. The drug is thought to exert its anthelmintic effect by blocking glucose uptake in the susceptible helminths, thereby depleting the energy level until it becomes inadequate for survival. Immobilization is followed by the parasite. These events may be a consequence of the binding and subsequent inhibition of parasite tubulin polymerization by Albendazole and its metabolites, although the drug also binds to human tubulin. Albendazole is extensively metabolized, probably in the liver. Albendazole is poorly absorbed from the gastrointestinal tract but rapidly undergoes extensive first-pass metabolism. The principal metabolite albendazole sulphoxide has anthelmintic activity and a plasma half-life of about 8.5 hrs. It is excreted in the urine together with other metabolites.

DOSAGE & ADMINISTRATION

Adults & children over 2 years:

400 mg (1 tablet or 10 ml suspension) as a single dose in cases of Enterobius vermicularis, Trichuris trichiura, Ascaris lumbricoides, Ancylostoma duodenale and Necator americanus.

For cystic echinococcosis, the 28 days course may be repeated after 14 days without treatment, to a total of 3 treatment cycles.
For alveolar echinococcosis, cycles of 28 days of treatment followed by 14 days without treatment, may need to continue for months or years.

PRECAUTIONS & WARNINGS

Blood counts and liver function tests before treatment and twice during each cycle; breastfeeding; exclude pregnancy before starting treatment. Albendazole should only be used in the treatment of Echinococcosis if there is constant medical supervision with regular monitoring of serum-transaminase concentrations and of leucocyte and platelet counts
