Plasma levels and postpartum breastmilk concentrations of sugammadex: a pharmacokinetic study in women undergoing general anaesthesia for caesarean delivery

Int J Obstet AnesthPublished Pharmacokinetic study

Authors' conclusion

The volume of distribution and clearance of rocuronium and sugammadex were at the upper end of published ranges from non-pregnant patients. Sugammadex was not detected or was below the lower limit of quantification in all breastmilk samples, providing reassurance regarding infant exposure in the early post-partum period.
