Retosiban also known as GSK-221,149-A[1][2] is an oral drug which acts as an oxytocin receptor antagonist. It is being developed by GlaxoSmithKline for the treatment of preterm labour.[3][4] Retosiban has high affinity for the oxytocin receptor (Ki = 0.65 nM) and has greater than 1400-fold selectivity[5] over the related vasopressin receptors
