Atosiban

EXPERIMENTAL

Women with twin pregnancy with preterm labor between 24 weeks 0 days and 32 weeks 6 days of gestation will be included and randomly assigned to the Atosiban group.

Drug: Atosiban

Nifedipine

EXPERIMENTAL

Women with twin pregnancy with preterm labor between 24 weeks 0 days and 32 weeks 6 days of gestation will be included and randomly assigned to the Nifedipine group.

Drug: Nifedipine

Interventions

After random allocation to a treatment group, women will receive Atosiban as follows: Atosiban was given as a single loading intravenous dose, 6.75 mg in 0.9% sodium chloride solution, followed by an intravenous infusion of 300 micrograms/min in 0.9% sodium chloride solution for the first 3 hours and then 100 micrograms/min for another 45 hours. The choice of the dose regimen for Atosiban was consistent with the recommendations of the product labeling.

Atosiban

After random allocation to a treatment group, women will receive Nifedipine as follows: Nifedipine was given as a loading dose of 20 mg orally followed by another two doses of 20 mg, 20-30 minutes apart as needed. Maintenance was started after 6 hours with 20-40 mg four times a day for a total of 48 hours.
