title: Effect of loperamide on stool output and duration of acute infectious diarrhea in infants.
abstract: This study was designed to assess the effect of loperamide, given to infants in higher than recommended doses, on the severity and duration of acute diarrhea. Thirty infants with acute diarrhea and dehydration were given loperamide (0.8 mg/kg/day), in addition to standard fluid therapy, for 48 hours after admission to the hospital. The stool output in grams per kilograms of body weight per day and the duration of diarrhea in these infants were compared with those in 30 matched control infants receiving only standard fluid therapy. Two infants given loperamide had to be withdrawn from the trial because ileus developed in one and the other had persistent severe vomiting. In four other infants receiving loperamide, drowsiness developed but resolved rapidly on discontinuation of the drug. Infants receiving loperamide had a shorter duration of diarrhea (median 2.5 vs 6.0 days) and lower daily stool output than the control subjects had. The study confirmed the efficacy of loperamide in reducing the duration and severity of diarrhea but raised doubts regarding its safety in the treatment of young infants.
