Trial Summary

What is the purpose of this trial?

This trial will test if Suvorexant can help people with opioid and stimulant use disorders reduce drug use, cravings, and stress while improving their sleep. Participants will receive Suvorexant for a period of time. The study aims to see if those taking Suvorexant have better outcomes. Suvorexant has been shown to improve sleep onset and maintenance in patients with insomnia.

Will I have to stop taking my current medications?

The trial requires that you stop using benzodiazepines, tranquilizers, or other schedule IV sleep medications. Also, you cannot use medications that are contraindicated (not safe to use) with the study.

How is the drug Suvorexant unique for treating opioid/stimulant co-use?

Suvorexant is unique because it is primarily used as a sleep aid, working by blocking orexin receptors in the brain, which is different from typical treatments for opioid or stimulant use that often target opioid receptors or dopamine pathways. ^{1 2 3 4 5}
