title: A comparative study on the efficacy of albendazole and mebendazole in the treatment of ascariasis, hookworm infection and trichuriasis.
abstract: A comparative study of the efficacy of albendazole and mebendazole was carried out in Pattani Province in the southern part of Thailand. One hundred and ninety-six patients with single or multiple infections with Ascaris, hookworm, and Trichuris were randomized into 4 groups for different treatments. Stool examination by Kato-Katz technique were done before and on day 14 after treatment. Results of the study showed that (1) a single dose of 300 mg mebendazole (locally produced) resulted in cure rates of 50%, 0% and 0% and egg reduction rates of 87.3%, -15.3%, and 28.3%, for ascariasis, hookworm infection and Trichuris respectively; (2) a single dose of 300 mg mebendazole (original) resulted in cure rates of 100.0%, 9.1%, and 43.3%, and egg reduction rates of 100.0%, 72.0%, and 77.9%, for Ascaris, hookworm, and Trichuris respectively; (3) a single dose 500 mg mebendazole (original) resulted in cure rates of 100.0%, 30.2%, and 70.3%, and egg reduction rates of 100.0%, 70.4% and 89.9%, for Ascaris, hookworm, and Trichuris respectively and (4) a single dose of 400 mg albendazole (original) resulted in cure rates of 100.0%, 84.3%, and 67.4%, and egg reduction rates of 100.0%, 96.0% and 87.0%, for Ascaris, hookworm, and Trichuris respectively. Both mebendazole and albendazole are safe and no side effects were observed. The results of this study suggested that albendazole is the preferred benzimidazole derivative for mass treatment of multiple infections with Ascaris, hookworm, and Trichuris.
