Incorporation of heme oxygenase inhibitors into phosphatidyl choline liposomes markedly enhanced localization of these agents within the spleen as compared with the localization observed following their administration in aqueous vehicle. The increased concentration of inhibitor within splenic microsomes led to a near complete and sustained blockade of heme oxygenase activity and thus to a marked diminution in biliary bilirubin output. These studies suggest that heme oxygenase inhibitors administered within liposomes may so effectively block bilirubin production in the human newborn that ancillary methods for treating this important clinical problem may be reduced to a minimum.
