The role of the intestinal microflora in the reductive metabolism of acenocoumarol in man. 1984

H H Thijssen, and L G Baars, and M J Hazen, and A E Van den Bogaard

Although the oral anticoagulant acenocoumarol (AC) is very effectively metabolized by the intestinal microflora to its amino metabolite, under clinical conditions this route of AC-disposition is of no importance because the compound is rapidly absorbed from its pharmaceutical application form. Only when the gastro-intestinal absorption is retarded, for instance by using a capsule as vehiculum, are appreciable amounts of reduced metabolites recovered in urine.

UI MeSH Term Description Entries
D007408 Intestinal Absorption Uptake of substances through the lining of the INTESTINES. Absorption, Intestinal
D007422 Intestines The section of the alimentary canal from the STOMACH to the ANAL CANAL. It includes the LARGE INTESTINE and SMALL INTESTINE. Intestine
D008297 Male Males
D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
D002214 Capsules Hard or soft soluble containers used for the oral administration of medicine. Capsule,Microcapsule,Microcapsules
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000074 Acenocoumarol A coumarin that is used as an anticoagulant. Its actions and uses are similar to those of WARFARIN. (From Martindale, The Extra Pharmacopoeia, 30th ed, p233) Acenocoumarin,Nicoumalone,Mini-Sintrom,Sinkumar,Sinthrome,Sintrom,Syncoumar,Syncumar,Synthrom,Mini Sintrom,MiniSintrom
D001711 Biotransformation The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.
