Atosiban and nifedipine in acute tocolysis: a comparative study.

Objective: The objective was to compare the effectiveness, efficacy, and safety of atosiban and nifedipine in preventing or delaying premature labor.

Design: An interventional, randomized, controlled trial of 63 women experiencing preterm labor varying from 24 to 35 completed weeks of gestation. The women were randomized to receive either atosiban intravenously (group I, n=31), or nifedipine orally (group II, n=32).
