Indomethacin for Tocolysis
Background: Indomethacin is frequently used as a tocolytic, however there is currently only scant evidence to support its efficacy.
Goals: To delay preterm delivery by 48 hours and to examine longer latency periods and maternal and neonatal outcomes Methods: Randomized placebo-controlled trial of indomethacin for tocolysis. Women with a singleton pregnancy between 23w0d and 31w6d in preterm labor randomly assigned to 50mg indomethacin by mouth followed by 25mg by mouth every 6hour for 48 hours or placebo. Patients receive betamethasone for fetal lung maturity, if not previously administered, and magnesium sulfate for neuroprotection. Ultrasound performed before initiation of study drug and after completion of study medication for amniotic fluid index and fetal cardiac assessment.

- delivery within 48 hours [ Time Frame: 48 hours after enrollment ] [ Designated as safety issue: No ]The percentage of patients remaining undelivered after 48 hours
- delivery within 7 days [ Time Frame: 7 days after enrollment ] [ Designated as safety issue: No ]The percentage of patients remaining undelivered after 7 days
- delivery before 37 weeks [ Time Frame: participants will be followed for the duration of pregnancy through their postpartum period, an expected time of up to 20 weeks ] [ Designated as safety issue: No ]The percentage of patients remaining undelivered until 37 weeks gestational age
- Maternal and Fetal Complications [ Time Frame: participants will be followed for the duration of pregnancy through their postpartum period and neonatal hospital stay, an expected time of up to 24 weeks ] [ Designated as safety issue: No ]composite of maternal intolerance of the drug, birth weight, gestational age, neonatal morbidities, changes in amniotic fluid volume, fetal cardiac assessment, or premature constriction of the ductus arteriosus.
