Repurposing existing drugs as a therapeutic approach for the prevention of preterm birth

Abstract

Preterm birth is the leading cause of neonatal morbidity and mortality globally. Despite extensive research into the underlying pathophysiology, rates of preterm birth have not significantly reduced. Currently, preterm labour management is based on optimising neonatal outcomes. Treatment involves administering drugs (tocolytics) to suppress uterine contractions to allow sufficient time for transfer to an appropriate facility and administration of antenatal corticosteroids for fetal lung maturation. Current tocolytics are limited as they are associated with adverse maternal and fetal effects and only delay delivery for a short period. There has been a serious lack of therapeutic development f..
