We developed a method based on liquid chromatography coupled with tandem mass spectrometry to quantify individual enantiomers of methadone and its primary metabolite, R/S-2-ethyl-1,5-dimethyl-3,3-diphenylpyrrolinium (EDDP), in postmortem blood and brain tissue. Samples were prepared with a Tecan Evo robotic system.
Methadone maintenance therapy is one of the most popular treatments for opiate addiction. The easiest and the most reliable way to monitor the accuracy of the therapy is determination of methadone and its metabolites in biological material. The aim of
Body fluids and tissues in 16 methadone (MTD)-associated fatalities were investigated to find out whether analysis of MTD and its metabolite 2-ethylidine-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) following enantioselective separation of both compounds may assist in the interpretation of MTD findings. Individual case histories

It may be advantageous to use sweat, rather than blood or urine, to monitor individuals' drug exposure for the purposes of drug treatment programs, employment initiatives, and forensic investigations. Forty-eight patients receiving methadone at the Public Service for the Treatment

Reports describing methadone overdose in adult and pediatric patient populations are not uncommon. Reports in the preterm neonate patient population, however, are infrequent even though the utilization of methadone in that population continues to increase. Significant age-related pharmacokinetic differences complicate
