The efficacy of Mebendazole and Niclosamide was studied in two groups of 24 and 38 cases, respectively of patients suffering from taeniasis. Mebendazole with dose schedule of 200 and 300 mg twice daily for 3 consecutive days showed a cure rate of 71.42% and 92.30%, whereas Niclosamide at the dose rate of 200mg per patient was 94.76% effective. Flubendazole showed a cure rate of 66.66% only. Mebendazole and Niclosamide possess high taeniacidal activity, ability to reduce the clinical symptoms of taeniasis without any side effects. Niclosamide with high activity and excellent tolerance, is a drug of choice for the treatment of taeniasis in single dose treatment while for hymenolepsiasis it needs extended course.

The streptothrinin antibiotics SQ 21,704 was evaluated against naturally occurring Taenia pisiformis and Dipylidium caninum infections in dogs when they were given at a dose level of 37.5 mg/kg of body weight in four different rations: loaf-type canned meat; chunk-type canned meat; dry (gravy-type) meal; and dry (pelleted) meal. The SQ 21,704 was 100% efficacious against both T pisiformis and D caninum infections when given with the chunk, gravy, and pelleted rations. When given with the loaf-type canned meat, it was 100% effective against T pisiformis and 60% efficacious against D caninum. The SQ 21,704 was effective against both tapeworm species when given orally as a liquid at a dose level of 37.5 mg/kg, formulated as an aqueous suspension containing 94 mg of activity per milliter. The SQ 21,704 was also tested in dogs when given orally in gelatin capsules at a dose level of 37.5 mg/kg without fasting, and was 100% efficacious against both tapeworm species. The results of a comparative taeniacidal study demonstrated that SQ 21,704 was 100% effective in removing both T pisiformis and D caninum when administered orally at a dose level of 37.5 mg/kg, whereas niclosamide and bunamidine hydrochloride were only partially effective at their recommended dose levels. One of five dogs treated with niclosamide at a dose level of 157 mg/kg was positive at necropsy, giving an orally efficacy of 80%. Three of five dogs treated with bunamidine hydrochloride at a dose level of 49 mg/kg were positive at necropsy, giving an overall efficacy of 40%.
