The drug of choice for the treatment of Schistosoma haematobium is
1.Praziquantel
2.Ceftriaxone
3.Metronidazole
4.Mebendazole
5.Diethylcarbamazine
Explanation
Praziquantel is a broadspectrum antihelminthic agent. It appears to kill the adult schistosome by increasing the permeability of the cell membranes of the parasite to Ca and consequent influx of Ca ions. This causes increased muscle contraction followed by paralysis.
