| pubmed-article:2128542 | pubmed:abstractText | Falirytmin (1) was metabolized in rats almost completely. Besides small amounts of 1 in urine and feces 18 metabolites could be separated. The proposed structures of 14 compounds demonstrate aromatic hydroxylation, N- and O-dealkylation, side-chain oxidation, alcohol dehydrogenation and N-acetylation. The main route of excretion of 1 and metabolites was with the feces. After p.o. or i.v. administration of 14C-O-ethyl-1 the average excretion of radioactivity in urine, feces and expired air was about 75% in 96 h. The residual activity in organs was about 2-2.5%. Whole-body autoradiography confirms these results. Only slight 14C-activity was seen in muscle, fat, liver, bone marrow and gut. | lld:pubmed |
