What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether amisulpride, an antipsychotic medication, can alter feelings about drugs like fentanyl during medical procedures. The focus is on whether amisulpride affects how much someone "likes" the drug effects. Participants will receive either amisulpride or a placebo before their procedure. The trial seeks individuals scheduled for surgery who will receive fentanyl and do not have lung or heart issues requiring special treatment or recent use of certain medications. As an Early Phase 1 trial, this research aims to understand how amisulpride works in people, offering participants a chance to contribute to groundbreaking medical knowledge.

Do I have to stop taking my current medications for the trial?

Yes, you will need to stop taking certain medications, including amisulpride, droperidol, levodopa, lithium, clozapine, metoclopramide, benzodiazepines, and opioids, to participate in this trial.

Is there any evidence suggesting that Amisulpride is likely to be safe for humans?

Research shows that amisulpride is generally well-tolerated in various situations. One study found that people taking amisulpride experienced similar safety and tolerability compared to other forms of the medication. Past studies have reported common side effects such as increased appetite, weight gain, and drowsiness. For most people, these effects were mild.

Amisulpride is already used in some treatments, providing some confidence about its safety. However, since this study is in the early stages, the researchers are still gathering detailed safety information specific to addiction treatment.12345

Why do researchers think this study treatment might be promising?

Amisulpride is unique because it targets dopamine receptors differently than typical treatments for addiction, which often focus on opioid receptors or behavioral therapies. While most traditional addiction treatments like methadone or buprenorphine are opioid-based, Amisulpride is an antipsychotic that works by modulating dopamine, a neurotransmitter involved in reward and pleasure pathways. This novel mechanism of action offers a fresh approach, potentially reducing cravings and withdrawal symptoms without the dependency risks associated with opioids. Researchers are excited about its potential to provide a safer and possibly more effective treatment option for those struggling with addiction.

What evidence suggests that Amisulpride might be an effective treatment for addiction?

Research has shown that amisulpride might help people struggling with addiction. Studies have found that individuals using amisulpride for various addictive substances experienced improvements, potentially reducing the urge or desire to use drugs. The medication appears effective even for those addicted to multiple substances. While these results are encouraging, this trial continues to study the treatment to confirm its effectiveness for addiction. Participants in this trial will receive either amisulpride or a placebo before fentanyl administration for their procedure.16789
