Official title
Interstitial Fluid Collection Validation Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research is to determine if common medications for opioid use disorder (i.e., buprenorphine/naloxone, buprenorphine, methadone) and their metabolites (norbuprenorphine \[a metabolite of buprenorphine\], buprenorphine-3-glucuronide \[B3G; a metabolite in buprenorphine\], ethylidene dimethyl diphenyl pyrrolidine \[EDDP; a metabolite of methadone\]) can be detected in the dermal interstitial fluid (i.e., fluid extracted from the surface of the skin). Additional subjects who are not prescribed or taking any of these medications will be included in this study to act as a comparison group
