Anthelmintic efficacy of mebendazole for pinworm infection of mice.

A series of 6 experiments was conducted to test the efficacy of mebendazole in eliminating naturally occurring pinworm infections from mice. Subjects treated with from 40-500 mg/kg of the drug harbored markedly fewer parasites than untreated controls. Treatment at 10 mg/kg appeared to be less effective. No mortality or overt signs of toxicity were observed in any of the experimental subjects.
