Gabapentin + Oxycodone for Recreational Opioid Use

This trial explores the potential for abuse of gabapentin, a medication sometimes used to treat nerve pain, when taken alone or with oxycodone, a common opioid painkiller. Researchers aim to understand how these medications affect individuals who use opioids recreationally, meaning for non-medical purposes. Participants will take either gabapentin, oxycodone, both together, or a placebo (a harmless pill with no active ingredients). Individuals who have used opioids recreationally at least ten times in the past year, but are not dependent on them, may be suitable for this trial. As a Phase 4 trial, this research seeks to understand how the FDA-approved treatment benefits a broader patient population.

Research has shown that gabapentin and oxycodone each present safety concerns. Studies have found that combining gabapentin and oxycodone can significantly increase the risk of serious issues, such as breathing problems and overdose. Gabapentin is often misused, and when combined with opioids like oxycodone, the risks can escalate.

Oxycodone alone, like other opioids, can cause serious side effects, including a slower heart rate, low blood pressure, and even heart failure. It also carries a high risk of addiction and overdose. Misusing opioids is a major concern, and using them with gabapentin can exacerbate these risks.

Researchers are excited about using gabapentin and oxycodone together for recreational opioid use because they target the condition differently than typical opioid treatments. While standard treatments often rely solely on opioids like methadone or buprenorphine, gabapentin works by calming nerve activity, potentially enhancing pain relief and reducing the need for higher opioid doses. By combining gabapentin with oxycodone, there’s hope for improved effectiveness with potentially fewer side effects and a reduced risk of dependency. This combination could offer a new pathway for managing recreational opioid use by addressing both pain and nerve activity simultaneously.

This trial will evaluate the effects of gabapentin and oxycodone, both separately and in combination, on recreational opioid use. Research has shown that gabapentin treats nerve pain and seizures, benefiting about 30–40% of patients with conditions like diabetic nerve pain. However, misuse can occur, especially when combined with opioids. Oxycodone, a strong painkiller, carries a high risk of misuse and addiction due to its euphoric effects. Combining gabapentin with oxycodone might increase misuse risk, as both drugs have been linked to abuse when used together. The effectiveness of this combination for treating recreational opioid use remains under study, with concerns about its potential for abuse.⁶⁷⁸⁹¹⁰
