Methadone Metabolite 300

Methadone, a Schedule II controlled substance, is often used in the treatment of opiate addiction and pain management; it also has a high potential for abuse. Methadone is metabolized primarily into two pharmacologically inactive metabolites, EDDP and EMDP. (2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine) represents a better urine marker for monitoring methadone maintenance than testing for un-metabolized methadone alone.
