Summary

This trial will test whether dronabinol, a medication derived from marijuana, is effective in relieving pain after arthroscopic knee surgery, with the hope of expanding the trial to other types of orthopedic surgery if results are promising.

Who is the study for?
Adults over 18 scheduled for knee arthroscopic surgery can join this trial. They must avoid alcohol, recreational or medical marijuana, CBD products, and certain medications during the study. Pregnant women, those breastfeeding or trying to conceive are excluded, as well as patients with allergies to study drugs, lactose intolerance, severe mental health conditions or substance abuse issues.
What is being tested?
The trial is testing if Dronabinol helps with pain after knee surgery compared to a placebo. It aims to see if it reduces the need for opioids and has minimal side effects. If successful in reducing postoperative pain without significant negative effects, the scope may broaden to other surgeries.
What are the potential side effects?
Dronabinol might cause dizziness, dry mouth, sleepiness or euphoria. Since it's related to cannabis (marijuana), there could be similar side effects like changes in mood or perception but likely less intense due to controlled dosing.
