Action/Kinetics: Acts by inhibiting tubular polymerization, resulting in the loss of cytoplasmic microtubules and inability of the cell to function. Poorly absorbed from the GI tract; enhance absorption by ingesting a meal containing at least 40 g of fat. Rapidly converted to albendazole sulfoxide, the active metabolite. Peak plasma levels, sulfoxide: 2-5 hr. t 1/2, terminal, of sulfoxide: 8-12 hr. Further metabolized to other metabolites with excretion through the bile, accounting for a portion of elimination.

Uses: Treatment of parenchymal neurocysticercosis due to Taenia solium. Treatment of cystic hydatid disease of the liver, lung, and peritoneum caused by the larval form of the dog tapeworm Echinococcus granulosus.

Miscellaneous: Fever, allergic reactions, acute renal failure.

Drug Interactions: Cimetidine / Levels of albendazole sulfoxide in bile and cystic fluid in hydatid cyst clients Dexamethasone / Possible plasma levels of albendazole sulfoxide Praziquantel / Plasma levels of albendazole sulfoxide
