Conference paper


Both intra-arterial and intravenous infusions of prostaglandin (PG)E1 have been used in the treatment of peripheral arterial occlusive disease [17]. However, only few data on the pharmacokinetics and metabolic fate of PGE1 in man are available so far [4, 6, 7, 10, 16]. We have recently described [13] plasma levels of PGE1 and its circulating metabolite 15-keto-13,14-dihydro-PGE1 (KH2PGE1) in the cubital vein of healthy volunteers receiving PGE1 infusions into the contralateral cubital vein. We have now compared plasma levels of PGE1 and KH2PGE1 in healthy volunteers treated with either intra-arterial or intravenous infusions of PGE1. Furthermore, since the initial metabolites of PGE1 15-keto-PGE1 and KH2PGE1 have only negligible biological activity [1, 18], we have additionally determined the occurrence of 13,14-dihydro-PGE1 (H2PGE1), a biologically active metabolite [1, 3, 18], during intravenous PGE1 infusions in patients with peripheral arterial occlusive disease [12].
