Metrifonate in urinary schistosomiasis A field trial in northern Nigeria

A field trial of metrifonate in the form of Bilarcil tablets (Bayer) was carried out in 39 northern Nigerian schoolchildren heavily infected with Schistosoma haematobium. Three oral doses of 7.5 mg/kg were given at four-week intervals. The drug proved effective (mean reduction in egg counts eight weeks after completion of treatment 94.5%) and was excellently tolerated. Its use on a larger scale is suggested.
