In the course of an evaluation of various schistosomicidal drugs In Iran, the effect of an organo-phosphorus compound in the-treatment of 45 mild cases of urinary bilhariziasis was assessed and the drug was given in 3 doses of 10 mg/kg body weight each with 3-week intervals. Follow-up examinations undertaken 3 weeks after the 1st, 2nd and 3rd doses as well as 3 months after completion of therapy showed cure rates of 71, 82, 91 and 90% responsively. A reverse correlation was observed between the mean number of eggs excreted in the urine and the cure rate. Side-effects were mild and were observed in only 20% of the patients. In order of their frequency, they were abdumina1 pain, nausea, headache, vertigo and vomiting. The administration of Atropine together with each dose of the drug did not have any effect on the reduction of side-effects.
