PRESCRIPTION DRUG
Albendazole is indicated for the treatment of the following infections: Neurocysticercosis: Albendazole is indicated for the treatment of parenchymal neurocysticercosis due to active lesions caused by larval forms of the pork tapeworm, Taenia solium . Lesions considered responsive to albendazole therapy appear as nonenhancing cysts with no surrounding edema on contrast-enhanced computerized tomography. Clinical studies in patients with lesions of this type demonstrate a 74% to 88% reduction in number of cysts; 40% to 70% of albendazole-treated patients showed resolution of all active cysts. Hydatid Disease: Albendazole is indicated for the treatment of cystic hydatid disease of the liver, lung, and peritoneum, caused by the larval form of the dog tapeworm, Echinococcus granulosus . This indication is based on combined clinical studies which demonstrated non-infectious cyst contents in approximately 80 to 90% of patients given albendazole for 3 cycles of therapy of 28 days each (see DOSAGE AND ADMINISTRATION

New Drug Application
ALBENDAZOLE- ALBENDAZOLE TABLET, FILM COATED LINEAGE THERAPEUTICS INC ---------- ALBENDAZOLE TABLETS RX ONLY DESCRIPTION Albendazole is an orally administered broad-spectrum anthelmintic. Chemically, it is methyl 5- (propylthio)-2-benzimidazolecarbamate. Its molecular formula is C H N O S. Its molecular weight is 265.34. It has the following chemical structure: Albendazole is a white to off-white powder. It is soluble in dimethylsulfoxide, strong acids, and strong bases. It is slightly soluble in methanol, chloroform, ethyl acetate, and acetonitrile. Albendazole is practically insoluble in water. Each white to off-white, film-coated tablet contains 200 mg of albendazole. Inactive ingredients consist of: carnauba wax, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, povidone, sodium lauryl sulfate, sodium saccharin, sodium starch glycolate, and starch. CLINICAL PHARMACOLOGY PHARMACOKINETICS : _ABSORPTION AND METABOLISM:_ Albendazole is poorly absorbed from the gastrointestinal tract due to its low aqueous solubility. Albendazole concentrations are negligible or undetectable in plasma as it is rapidly converted to the sulfoxide metabolite prior to reaching the systemic circulation. The systemic anthelmintic activity has been attributed to the primary metabolite, albendazole sulfoxide. Oral bioavailability appears to be enhanced when albendazole is coadministered with a fatty meal (estimated fat content 40 g) as evidenced by higher (up to 5-fold on average) plasma concentrations of albendazole sulfoxide as compared to the fasted state. Maximal plasma concentrations of albendazole sulfoxide are typically achieved 2 to 5 hours after dosing and are on average 1.31 mcg/mL (range 0.46 to 1.58 mcg/mL) following oral doses of albendazole (400 mg) in 6 hydatid disease patients, when administered with a fatty meal. Plasma concentrations of albendazole sulfoxide increase in a dose-proportional manner over the therapeutic dose range following ingestion of a fatty meal (fat content 43.1 g).
