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. Methadone has a slow metabolism and very high fat solubility, making it longer lasting than morphine-based drugs. Methadone has a typical
Methadone is secreted in saliva, breast milk, amniotic fluid and umbilical cord plasma. Metabolism: Methadone is primarily metabolized by N-demethylation to

There is no evidence of gabapentin metabolism in humans and it is methadone or S-methadone. There was no change in sofosbuvir Cmax, but AUC
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.
