Official title
The Pharmacokinetic Interaction Between Metformin and Nizatidine in Healthy Volunteers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will address the following question: Does nizatidine affect the pharmacokinetics of metformin in healthy volunteers? Recent studies in the Giacomini laboratory have indicated that nizatidine may block metformin elimination from the kidney by inhibiting organic cation transporter efflux of metformin. The investigators hypothesize that the co-administration of metformin and nizatidine will reduce the renal clearance (CLR) of metformin leading to increased plasma concentrations and potential risk for toxicities. Knowledge of the pharmacokinetic interaction profile of metformin with organic transporter inhibitors, such as nizatidine, is important to help develop safer more effective drug therapy with reduced side effects.
