title: Efficacy of divided doses of GS-23654 against immature Echinococcus granulosus infections in dogs.
abstract: One hundred dogs were used to evaluate the efficacy of GS-23654 (4-nitro-4'-isothiocyano-diphenyl-ether) against immature Echinococcus granulosus. A 25% suspension of active ingredient was administered at dose rates of 100, 200, or 400 mg/kg of body weight on 1, 2, or 3 occasions. Anthelmintic efficacy was dosage dependent and increased with the number of times the dosage was repeated. At none of the treatment schedules tested were all worms eliminated from all dogs, although 92.6% of the expected number of worms were eliminated from dogs given 400 mg/kg on 3 occasions.
