How blocking orexin affects cravings for opioids and methamphetamine

Official title: Influence of Orexin Antagonism on Opioid and Methamphetamine Demand

Funded at Johns Hopkins University · NIH-11007205 · Data updated 2026-11-12

This study is looking at how a brain system called orexin affects cravings for opioids and methamphetamine in people who use both drugs, to help find better ways to treat addiction.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals diagnosed with opioid use disorder who may also be using methamphetamine.

Less likely to help

Patients who do not have a history of opioid or methamphetamine use are unlikely to benefit from this research.

What this research studies

This research investigates the role of the orexin system in regulating cravings for opioids and methamphetamine, particularly among individuals who use both substances. By employing a behavioral economic framework, the study aims to understand how motivation for using these drugs changes when orexin is blocked. Participants will be assessed to determine if opioids and methamphetamine act as substitutes or complements in their usage, which could inform future treatment strategies. The findings could lead to new approaches for managing addiction in patients with opioid use disorder.

Why it matters

Potential benefit: If successful, this research could lead to new treatment options for individuals struggling with opioid and methamphetamine addiction.

How similar studies have gone: Previous research has shown promise in targeting the orexin system for addiction treatment, suggesting that this approach may yield beneficial results.
