“…Mebendazole [methyl 5-benzoyl-2-benzimidazole carbamate] (Vermox; Janssen) was reported to be inactive against the infective larvae in immunosuppressed dogs, and has little effect on the parasite in muscle tissue of mice (Grove, 1982a). Use of cambendazole ([5-isopropoxycarbonylamino-2-(4thiazyl) benzimidazole] (Merck, Sharp & Dohme) has been banned as a result of its linkage to several fatal idiosyncratic reactions in cattle (Hogg, 1978;Main and Vass, 1980). Alternatively, ivermectin [22,23-dihydroavermectin B 1 ] (Merck, Sharp & Dohme), a broad-spectrum, commercial drug (Fisher, 1985;Grove, 1989) that is a synthetic, lipophilic, macrocyclic lactone (Gustafsson et al 1987;Campbell, 1989), bears promise as an efficacious treatment against strongyloidosis (Naquira et al 1989;Marti et al 1996).…”
