OARS Trial Summary

This trial will test the hypothesis that a combination of over-the-counter non-opioid containing analgesics is at least as, if not more, effective (non-inferior) than the most commonly prescribed opioid analgesic.

Who is the study for?
Adults over 18, in good health, needing wisdom tooth removal can join this trial. They must understand English and consent to the study's procedures. Women should use contraception like pills or IUDs. Those with asthma, allergies to pain meds, heavy alcohol use, drug abuse history or taking certain medications cannot participate.Check my eligibility
What is being tested?
The study is testing if a mix of two non-opioid painkillers works as well as an opioid-based one for managing post-wisdom tooth extraction pain. Participants will be randomly assigned to receive either the non-opioid combination or the standard opioid analgesic without knowing which one they're getting.See study design
What are the potential side effects?
Possible side effects may include allergic reactions to the analgesics used (ibuprofen and acetaminophen), gastrointestinal issues such as bleeding or ulcers from ibuprofen, liver damage from acetaminophen overdose, and respiratory depression from opioids.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

If this research project is successful, how many different places could it be implemented?

"At the moment, this experiment is taking place at 5 different hospitals. The sites are situated in Rochester, Baltimore, Chicago and 2 other cities. If you want to cut down on travel, it would be best to select the location nearest to you."

Answered by AI

Could you explain the potential risks associated with Non-Opioid treatments?

"There is already some evidence to support the efficacy of Non-Opioid medication, as this is a Phase 3 trial. Furthermore, multiple rounds of data have also been collected to support its safety, so it received a score of 3."
