Methadone: Inhibits the metabolism of methadone and raises serum levels. Omeprazole (Losec, Prilosec)
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

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 differs with extended use, which can cause it to stay in the body even longer. Methadone is metabolized extensively, so
The CYP isozymes also demonstrate different affinities for metabolizing the different methadone enantiomers: CYP2C19, CYP3A7, and CYP2C8 preferentially metabolize (R)-methadone while CYP2B6, CYP2D6, and CYP2C18 preferentially metabolize (S)-methadone. CYP3A4 does not have an enantiomer preference.
