Ceftizoxime concentrations are higher in cord blood and amniotic fluid than in maternal blood. More avid binding to fetal serum proteins is a suggested mechanism. We measured ceftizoxime protein binding in fetal and maternal blood and documented significantly less protein binding to fetal proteins (21.9% vs 57.8%).
