Metformin and cocaine interactions in the brain

Official title: Investigating metformin and cocaine interactions in the brain at the level of pharmacokinetics, physiology, and proteomics

Funded at University of Minnesota · NIH-11428085 · Data updated 2026-11-12

A study explores whether metformin, a common diabetes medicine, could help treat cocaine use disorder by studying how the drug works in the brain.

Who could benefit from this research

Could help

Adults with cocaine use disorder who could potentially benefit from future therapies and may have coexisting metabolic health considerations.

Less likely to help

People without cocaine use disorder or those for whom metformin is not suitable due to medical conditions may not benefit.

What this research studies

This project looks at how metformin behaves in the brain when combined with cocaine, including how it moves around and interacts with brain cells. Scientists will examine the cellular and molecular mechanisms behind metformin’s effects on cocaine-related behaviors, with an eye toward translating findings into clinical options for people struggling with cocaine use disorder. The approach includes pharmacokinetic studies and analysis of brain signaling pathways, such as AMPK and transporter proteins, to understand how metformin might reduce cocaine-seeking behaviors. The goal is to move from preclinical findings toward targeted therapies that could benefit patients with cocaine use disorder who also have type 2 diabetes or metabolic concerns.

Why it matters

Potential benefit: If successful, this work could lead to a new, repurposed treatment option for cocaine use disorder that leverages an already approved diabetes medication.

How similar studies have gone: Previous preclinical studies show that metformin can reduce cocaine-related behaviors in animal models, supporting further exploration.
