Healthy Volunteers Clinical Trial
Official title:
Role of CYP2B6 Polymorphisms in Methadone Metabolism and Clearance
This research study will determine if genetic variation in CYP2B6 affects how the body metabolizes methadone.
This investigation determined the influence of CYP2B6 genetic variation, specifically CYP2B6*6 polymorphism, on clinical methadone plasma concentrations, clearance, and metabolism. The hypothesis was that CYP2B6*6 heterozygotes or homozygotes would have reduced metabolism and clearance. A secondary objective was to evaluate other less common genotypic variants, when encountered. Healthy volunteers in genotype cohorts CYP2B6*1/*1, CYP2B6*1/*6 , and CYP2B6*6/*6, and also CYP2B6*4 and CYP2B6*5 carriers, received single doses of IV and oral methadone. Plasma and urine methadone and metabolite concentrations were determined by tandem mass spectrometry. The primary outcome measure was methadone metabolism, measured as plasma metabolite/patent area under the concentration-time curve ratio and metabolite formation clearance. ;
