Summary

This trial will study the effects of Epidiolex, a cannabidiol medication, on patients undergoing a common knee surgery. The goal is to see if Epidiolex can help reduce pain and the need for opioids.

Who is the study for?
This trial is for adults aged 18-75 scheduled for bilateral knee replacements who are generally healthy (ASA Physical Status 1 or 2). It's not for those with severe health issues, recent cannabis use, chronic opioid use, certain medication usage, or major psychiatric history.
What is being tested?
The study tests Epidiolex®, an FDA-approved oral CBD solution. Participants will receive either a placebo, 400mg or 800mg of Epidiolex® to see if it reduces opioid need and pain after knee surgery while checking its safety and effects on body inflammation.
What are the potential side effects?
While the side effects aren't detailed here, CBD can typically cause drowsiness, changes in appetite/weight, diarrhea, fatigue. The trial will monitor tolerability and any adverse reactions.
