Effectiveness and safety of the oxytocin antagonist atosiban versus beta-adrenergic agonists in the treatment of preterm labour. The Worldwide Atosiban versus Beta-agonists Study Group.
To compare the effectiveness and safety of the oxytocin antagonist atosiban with conventional beta-adrenergic agonist (beta-agonist) therapy in the treatment of preterm labour. ⋯ In the largest study of tocolytic therapy to date, atosiban was comparable in clinical effectiveness to conventional beta-agonist therapy, but was associated with fewer maternal cardiovascular side effects. We conclude that atosiban has clinical advantages over current tocolytic therapy.
