Application

Praziquantel is a potent anthelmintic used against schistosome and many cestode infestations. It is used to study voltage-gated Ca2+ channels and is a potential small molecule neurogenic.

Biochem/physiol Actions

Praziquantel increases the permeability of the tegmentum to Ca2+ which results in the contraction of schistosomes and death. Praziquantel causes vacuolization and disintegration of the schistosome tegument. It is more effective on adult worms than young worms. It inhibits glucose uptake, which lowers glycogen levels and stimulates lactate release. Praziquantel is a potent anthelmintic against parasitic flatworms (flukes and tapeworms). Recent studies have indicated that praziquantel binds to a varient of the β-subunit of the voltage gated Ca2+ channel and to actin, which is a component of some Ca2+ channels.

IgE specific to worm antigen (SWA) and pre-treatment eosinophil number, are associated with human immunity to re-infection with schistosomes after chemotherapeutic treatment. Treatment significantly elevates circulating IL-5 24-hr post-treatment of Schistosoma mansoni. Here we investigate if praziquantel treatment of human
