The maternofetal transfer of the beta1-selective adrenergic antagonist
celiprolol has been studied in four hypertensive pregnant women. Feta
l plasma concentrations were about 25-50 % of the levels found on the
maternal side. There was no significant difference between the plasma
concentrations of the two enantiomers in the child. Therefore, in furt
her investigations only the racemate needs to be determined.
