Albendazole is an anthelmintic or anti-worm medication. It prevents newly hatched insect larvae (worms) from growing or multiplying in the body. It is effective (first line of treatment) against: Flatworms Flukes/trematodes Tapeworm/cestodes Echinococcosis Nematodes Hookworms Roundworms Whipworms Threadworms or pinworms In Africa albendazole (donated by GlaxosmithKline)is being used to treat lymphatic filariasis as part of efforts to stop transmission of the disease. In sub- Saharan Africa, albendazole in used in conjunction with ivermectin, and elsewhere in the world, the medicine is used in combination with diethylcarbamazine. In Brazil and another countries is used against giardiasis.

Pharmacodynamics

Inhibits effect on tubulin polymerization, resulting in loss of cytoplasmic microtubules.

Pharmacokinetics

Absorption: Albendazole is poorly absorbed from the GI tract; however, it is rapidly converted to its primary active metabolite, albendazole sulfoxide, prior to reaching systemic circulation. Fatty meals enhance bioavailability, as indicated by up to a 5-fold increase in plasma concentration in albendazole sulfoxide. Albendazole sulfoxide plasma concentrations are dose dependent. C max is achieved in 2 to 5 h and ranges from 0.46 to 1.58 mcg/mL, with a fatty meal.


Distribution: Albendazole sulfoxide is 70% protein bound and widely distributed throughout the body. Metabolism After metabolism in the liver to albendazole sulfoxide, it is further metabolized to albendazole sulfone and other oxidative metabolites.


Elimination: Albendazole sulfoxide elimination is 8 to 12 h. Biliary elimination of albendazole sulfoxide results in biliary concentrations similar to plasma concentration. Urinary excretion is a minor elimination pathway (less than 1%).


Special Populations Hepatic Function Impairment Systemic availability of albendazole sulfoxide is increased in patients with extrahepatic obstruction.

Albendazole Adverse Reactions / Albendazole Side Effects

CNS Headache (11%); raised intracranial pressure (2%); dizziness/vertigo, meningeal signs (1%). Dermatologic Reversible alopecia (2%); erythema multiforme, hypersensitivity including rash and urticaria (less than 1%); Stevens-Johnson syndrome (postmarketing). GI Abdominal pain, nausea/vomiting (6%). Genitourinary Acute renal failure (postmarketing). Hepatic Abnormal LFTs (16%); hepatitis (postmarketing). Hematologic-Lymphatic Leukopenia (less than 1%); agranulocytosis, granulocytopenia, pancytopenia, thrombocytopenia (rare); aplastic anemia (postmarketing). Miscellaneous Fever (1%).

Precautions

Monitor blood cell counts and liver function (transaminases) at the beginning of each 28-day cycle of therapy and every 2 wk while on therapy. Discontinue therapy if liver enzymes are significantly increased. Treatment can be resumed when hepatic enzymes have returned to pretreatment levels, but perform lab tests frequently during repeat therapy.

Special Precautions

Monitor blood counts and liver function. Administer within 7 days of start of normal menstruation in women of childbearing age. Adequate nonhormonal contraceptive measures must be taken during and for 1 mth after therapy. Perform liver function tests and blood counts before and every 2 wk during high dose therapy of hydatid disease.

Other Drug Interactions

Cimetidine In hydatid cyst patients, albendazole sulfoxide concentrations in bile and cystic fluid may be increased about 2-fold; however, plasma levels are unchanged 4 h after dosing. Dexamethasone Albendazole C trough at steady state was about 56% higher when coadministered with dexamethasone 8 mg. Praziquantel Albendazole sulfoxide C max may be elevated about 50%, increasing the risk of adverse reactions. Theophylline Although theophylline pharmacokinetics are unchanged by albendazole, monitor plasma concentrations during and after albendazole treatment.

Other Interactions

Food Interactions Grapefruit juice: Plasma concentrations may be elevated and the T may be shortened.
