Nifedipine in the management of preterm labor

These US authors conducted a meta-analysis of randomized controlled trials to determine the efficacy and safety of nifedipine as a tocolytic agent in women with preterm labor. Twenty-six trials (2179 women) were included.

They found: "Nifedipine was associated with a significant reduction in the risk of delivery within 7 days of initiation of treatment and before 34 weeks' gestation, respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage, neonatal jaundice, and admission to the neonatal intensive care unit when compared with beta2-adrenergic-receptor agonists. There was no difference between nifedipine and magnesium sulfate in tocolytic efficacy. Nifedipine was associated with significantly fewer maternal adverse events than beta2-adrenergic-receptor agonists and magnesium sulfate. Maintenance nifedipine tocolysis was ineffective in prolonging gestation or improving neonatal outcomes when compared with placebo or no treatment."

The authors concluded: "Nifedipine is superior to beta2-adrenergic- receptor agonists and magnesium sulfate for tocolysis in women with preterm labor."

Nifedipine is also easy to administer.
