Suvorexant for Opioid/Stimulant Co-use
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether Suvorexant (also known as Belsomra) can aid individuals using both opioids and stimulants by reducing drug use and cravings, and improving sleep and stress levels. Participants will receive either Suvorexant or a placebo (a pill with no active ingredients). The trial seeks individuals diagnosed with a stimulant use disorder who are currently stable on methadone or buprenorphine treatment for opioid use disorder. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.
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.
Is there any evidence suggesting that Suvorexant is likely to be safe for humans?
Research has shown that Suvorexant is generally safe and well-tolerated. In studies involving individuals with sleep difficulties, Suvorexant demonstrated a strong safety record, with most participants not experiencing serious side effects. Common side effects, such as sleepiness or dizziness, are usually mild.
One study examined Suvorexant's effects on individuals with opioid use disorder to assess its potential to improve sleep. This study also found Suvorexant to be safe for participants.
While Suvorexant is approved for treating insomnia, its use in individuals with opioid and stimulant use disorders remains under investigation. Researchers are evaluating its effectiveness and safety for this new purpose. Current evidence suggests it is safe to try.12345Why do researchers think this study treatment might be promising?
Unlike the standard care options for opioid and stimulant co-use, which typically involve therapies like methadone or buprenorphine for opioids and behavioral therapies for stimulants, Suvorexant offers a unique approach by targeting the orexin system in the brain. Most treatments focus on managing withdrawal symptoms or blocking the effects of the drugs. However, Suvorexant, originally designed for insomnia, works differently by potentially reducing cravings and improving sleep through its action as an orexin receptor antagonist. Researchers are excited about Suvorexant because it could offer a dual benefit: addressing sleep disturbances common in substance use disorders while also potentially reducing the urge to use these substances.
What evidence suggests that Suvorexant might be an effective treatment for opioid and stimulant co-use?
Research has shown that suvorexant, which participants in this trial may receive, may help individuals with opioid and stimulant use disorders by improving sleep and reducing cravings. Studies have found that suvorexant can address sleep problems related to cocaine withdrawal and lessen the urge to use cocaine. Early results suggest that suvorexant can increase sleep time during opioid withdrawal without causing addiction. Additionally, early research indicates it may effectively reduce drug cravings. This evidence supports the potential of suvorexant to assist with sleep issues and cravings in individuals dealing with these substance use disorders.12678
