The effects of indomethacin on renal function and intracranial hemorrhage in infants with patent ductus arteriosus.

The effects of indomethacin on patent ductus arteriosus (PDA) were retrospectively studied by evaluating 1,600 consecutive infants <36 weeks gestation from 1983 to 1986. Two hundred thirteen infants were diagnosed with a PDA, and 102 infants received indomethacin. Indomethacin was associated with successful PDA closure in 81 infants (79%), with 59 infants (58%) closing after a single dose. No cases of renal failure were observed after indomethacin
