Efficiency of a combined paste formulation of praziquantel/febantel against immature Echinococcus granulosus and immature Echinococcus multilocularis

: A combined paste formulation of praziquantel (1 mg/kg of body wt)/febantel (10 mg/kg) given for 3 consecutive days gave 100% clearance of immature Echinococcus granulosus and E multilocularis in experimentally infected dogs. The formulation was extremely convenient to administer. Adverse reactions were not noted in the treated animals.
