 Use of Praziquantel


Praziquantel is an anthelmintic effective against flatworms.Target: AntiparasiticPraziquantel is the drug of choice for treatment of all human schistosomes. Infected mice were treated with increasing Praziquantel doses until the highest dose of 3 × 300 mg/Kg was reached. The effect of Praziquantel treatment on the parasite population was assessed using five polymorphic microsatellite markers. Parasitological and genetic data were compared with those of the untreated control. After six parasite generations submitted to treatment, it was possible to obtain a S. mansoni population with decreased susceptibility to Praziquantel. In our experiments we also observed that female worms were more susceptible to Praziquantel than male worms [1, 2].
