Memory boost for cocaine users? small study tests potassium channel blocker

NCT ID NCT07532460

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at whether a drug called fampridine, which blocks potassium channels in the brain, can improve working memory in people with cocaine use disorder. Forty chronic cocaine users will receive either the drug or a placebo and then take memory tests. The goal is to understand the brain mechanisms behind cognitive problems in cocaine users, not to test a cure.
