Objective : To compare efficacy and side effects of ibuprofen versus indomethacin treatment for symptomatic patent ductus arteriosus (PDA) in preterm infants.
Method : The authors studied 30 infants (gestational age ~ 35 weeks, aged ~ 10 days) who were diagnosed as having symptomatic PDA confirmed by echocardiogram. The infants were randomly assigned to receive three intravenous doses of indomethacin given at 12 -hour intervals or three doses of ibuprofen given at 24-hour intervals, starting within ten days of life. The demographic data, rate of clinical closure, need for additional treatment, side effects, complications and the infants' clinical course were recorded within 28 days.
Results : The rate of ductal closure was similar with the two treatment regimes. Ductal closure occurred in 7 of 15 infants given ibuprofen (46.67%) and 10 of 15 infants given indomethacin (66.67%). = (Relative risk 0.669; 95% confidence interval, 0.328 to 1.364; p 0.462) The number of infants who needed a second pharmacologic treatment was not significantly different between the two groups. (6 cases in the ibuprofen group, 5 cases in the indomethacin group) but surgical ligation was performed in two cases in the indomethacin group. There was a significant difference in using the diuretic drug = (furosemide) in the indomethacin group (11 cases), compared to the ibuprofen group (3 cases), (p 0.009). More cases of necrotizing enterocolitis were seen in the indomethacin group (66.67% compared to 40% in the ibuprofen group) but there was no statistically significant difference.
Conclusion : Ibuprofen has the same efficiency as indomethacin for the treatment of sympto matic patent ductus arteriosus in preterm infants and less likely to induce necrotizing enterocolitis and renal toxicity than indomethacin.
