“Background\n\nPreventing preterm labour is the most important step in preventing preterm birth. Prostaglandins play an important role in labour and birth. Prostaglandin production can be obstructed by inhibition of the cyclo-oxygenase (COX) enzyme and this may arrest uterine contraction. RG7112 A Cochrane review on COX inhibitors for the treatment

of preterm labour found insufficient data to draw conclusions about its effectiveness.\n\nObjectives\n\nTo assess the effectiveness and safety of COX inhibitors for preventing preterm labour in high-risk women.\n\nSearch methods\n\nWe searched the Cochrane Pregnancy and Childbirth Group’s Trial Register (30 June 2012).\n\nSelection criteria\n\nAll published and unpublished randomised trials evaluating administration of any COX inhibitor for prevention of preterm labour in pregnant women at gestational age less than 36 weeks at risk of, but not experiencing, preterm labour. Cluster-randomised trials were

eligible for inclusion. Quasi-randomised trials and studies with cross-over designs were excluded.\n\nData collection and analysis\n\nTwo review authors (T Khanprakob and U Sangkomkamhang) independently assessed all potential studies for inclusion. Disagreement was resolved by discussion check details and, where necessary, by consultation with a third review author. Two review authors independently assessed trial quality and extracted data. Data were checked for accuracy.\n\nMain results\n\nWe included one randomised trial (involving 98 women) that evaluated the effectiveness of one type of COX inhibitor (rofecoxib) for preventing preterm birth. The included study did not report any data for one of our selleck chemicals primary outcomes: preterm labour. Rofecoxib use was associated with an increased risk for preterm birth and preterm premature rupture of membranes (PPROM). Rofecoxib was associated with a higher risk of oligohydramnios and low fetal urine production but the effects were reversible after stopping treatment. There were no differences in the number of women who discontinued treatment before 32

weeks of gestation. There was no difference in neonatal morbidities and admission to neonatal intensive care unit. There were no maternal adverse effects or perinatal mortalities in either group.\n\nAuthors’ conclusions\n\nThere was very little evidence about using COX inhibitors for preventing preterm labour. There are inadequate data to make any recommendation about using COX inhibitor in practice to prevent preterm labour. Future research should include follow-up of the babies to examine the short-term and long-term effects of COX inhibitors.”
