Description

2-Ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine, also known as EDDP, is a major inactive metabolite of the opioid methadone. Methadone is an opioid drug that is often used to treat addiction to other opioids, such as heroin, oxycodone or fentanyl. Methadone is metabolised in the liver and small intestine where it is converted to EDDP through N-demethylation and cyclization by CYP3A4 (PMID: 15501692 , 27320437 ). EDDP and methadone are eliminated through the kidneys. As such it is common to monitor the urine of patients in a clinical and forensic settings. EDDP is formed through N-desmethylmethadone reacting with itself and cyclizing through condensation of the secondary amine with the carbonyl group (PMID: 27320437 ). EDDP belongs to the family of compounds known as Diphenylmethanes. These are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups. EDDP is only found in individuals who have taken or been given methadone.
