Summary

This study tests whether methylphenidate (Ritalin) can help weaken memories that link drug cues to cocaine use. Fifty-one adults with cocaine use disorder will receive either methylphenidate or a placebo before recalling drug-related memories, while brain activity and skin responses are measured. The goal is to see if this approach reduces cravings and the return of drug memories, potentially leading to better addiction therapies.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Methylphenidate
What this could lead to
If it works, this could point toward a new cue-exposure therapy that reduces cravings and relapse risk in cocaine addiction.
What could go wrong
This is a very early, small study (51 people) testing a single dose. It may not translate into real-world treatment, and methylphenidate can raise heart rate and blood pressure.
