RT Journal Article SR Electronic T1 Biotransformation of Drugs in Human Skin JF Drug Metabolism and Disposition JO Drug Metab Dispos FD American Society for Pharmacology and Experimental Therapeutics SP 247 OP 253 DO 10.1124/dmd.108.024794 VO 37 IS 2 A1 Craig K. Svensson YR 2009 UL http://dmd.aspetjournals.org/content/37/2/247.abstract AB Although it is the largest organ of the human body, skin is often not considered in discussions of drug metabolism. However, there is growing evidence that most common drug-metabolizing enzymes are expressed in the skin. Evidence for expression of cytochromes P450, flavin monooxygenases, glutathione-S-transferases, N-acetyltransferases, and sulfotransferases in human skin and skin cells are presented. Additional discussion is focused on the evidence of actual metabolism of drugs. Finally, the potential clinical implications of metabolism within the skin are discussed briefly.
