Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older who require the removal of at least one impacted third molar and have a BMI between 18-35.

Probably not a fit

Patients with a history of chronic opioid or gabapentin use, hypersensitivity to gabapentinoids, or significant medical conditions may not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of administering 600 mg of gabapentin two hours before wisdom teeth extraction to reduce intraoperative and postoperative opioid use while managing pain. It is a double-blind, randomized, placebo-controlled study involving 49 patients, who will be monitored for pain severity, opioid consumption, and side effects at various intervals post-surgery. The goal is to determine if gabapentin can provide adequate pain control and minimize reliance on opioids during recovery.

Why it matters

Potential benefit: If successful, this approach could significantly reduce opioid consumption and improve pain management for patients undergoing wisdom teeth extraction.

How similar studies have gone: Previous studies in other surgical specialties have shown promising results for gabapentin in reducing opioid use, but this specific application in oral and maxillofacial surgery is novel.
