Methadone metabolism. Methadone, a racemic mixture of R-methadone and S-methadone ( mixture), is metabolized predominantly in the liver by N-demethylation in to a major metabolite, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine, which is further N-methylated to an inactive metabolite, EMDP. The major metabolites of methadone are 2
Metabolism of methadone to inactive forms is the main form of elimination. Oral delivery of methadone makes it subject to first-pass metabolism by the liver
Methadone is metabolized in the liver with no active metabolites. A number of medications can change methadone s absorption, distribution, and metabolism. Methadone s absorption is
Methadone metabolism. Methadone is metabolised almost exclusively by the liver [10]. The main biotransformation of the two methadone enantiomers is the N-demethylation [40] by CYP3A4 [41]. CYP3A4 is found in the small intestine and in the liver; therefore, it affects both the intestinal and hepatic metabolism of methadone.
