Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The objective of this study is to confirm the feasibility of using a panel of endogenous substrates/metabolites as a robust biomarker of OCTs and OATs by conducting a controlled, comprehensive clinical drug-drug interaction study in healthy adult volunteers. Metformin and furosemide will be used as probe drugs for OCTs and OATs, respectively; cimetidine and probenecid will be used as corresponding inhibitors. Results from this study will validate this novel approach, which will be extended to children by collaborators at Children's Mercy Hospital in Kansas City, MO.
