The Developing Liver: The Steady‐State Disposition of Propranolol in Pregnant Sheep
George W. Mihaly, Denis J. Morgan, Richard Smallwood, Kenneth J. Hardy – 1 May 1982 – The steady‐state disposition of the β‐adrenoreceptor blocking drug, propranolol, and its metabolite, 4‐hydroxypropranolol, was studied in the anesthetized pregnant sheep near term. Following infusion of propranolol to the mother, steady‐state plasma concentrations were obtained at three dosage levels in each of the eight animals studied. Blood samples were obtained from: (i) maternal facial artery and hepatic vein; (ii) umbilical vein, and (iii) fetal carotid artery, portal vein, and right hepatic vein.
