Albendazole in the treatment of strongyloidiasis

Albendazole was used to treat 30 patients with Strongyloides stercoralis infections. There were 21 males and 9 females, 13 to 68 years of age, who were divided into two groups of 11 and 19, respectively. Repeated pre- and post-treatment stool examinations were done by simple direct smear and formalin-ether concentration, and larval quantitations were done by the Stoll and Sasa's technique. Group I patients were given albendazole in dosages of 400 mg/day in divided doses for 3 days. Group II patients were given similar dosages, but were treated again 7 days later on the same schedule. Patients in Group I were followed for 14 days and those in Group II for 30 days. The cure rates were 73% for Group I and 100% for Group II. Side effects were minimal and transient. Albendazole is recommended for the treatment of strongyloidiasis in dosages of 400 mg/day in divided doses for 3 days with treatment repeated one week later.
