[Results obtained on S. haematobium by Oltipraz in Niger (author's transl)]

Sixty-three outpatients shedding eggs of S. haematobium were treated with 35 mg/kg oltipraz given in two divided doses on a single day (Niamey). 75% of the patients were egg-negative at one month and 88.9% at three months. Urinary egg excretion was markedly reduced (98%) and the mean egg count per 10 ml urine decreased from 33 before dosing to 0.6 at two months. Oltipraz thus appears to be a most interesting drug for urinary schistosomiasis
