JF Drug Metabolism and Disposition JO Drug Metab Dispos FD American Society for Pharmacology and Experimental Therapeutics SP 255 OP 265 VO 11 IS 3 A1 S Steffenrud YR 1983 UL http://dmd.aspetjournals.org/content/11/3/255.abstract AB Tritium-labeled 9-deoxo-16,16-dimethyl-9-methylene prostaglandin E2 was administered by intravenous injection into humans. The initial half-life in plasma was determined to be about 3 min. About 35% of the injected radioactivity was excreted in the urine and about 55% in the feces. Twenty-three urinary metabolites were identified. The metabolites included beta-oxidized and omega-oxidized products as well as metabolites in which the 9-methylene group had been biotransformed.
