Association between ß2-adrenergic receptor gene polymorphisms and adverse events of ritodrine in the treatment of preterm labor: a prospective observational study

摘要

BackgroundRitodrine, a tocolytic β2-agonist, has been used extensively in Europe and Asia despite its safety concerns. This study was designed to identify associations between β2-adrenergic receptor (ADRB2) polymorphisms and adverse drug events (ADEs) in patients with preterm labor treated with ritodrine.
