Pilot Randomized Control Trial Comparing Oral Ketamine and Oral Oxycodone for Pain Control in Emergency Department Patients (PKORCT)

June 22, 2026 updated by: Michael Waxman, Albany Medical College

The goal of this pilot randomized clinical trial is to learn if oral ketamine intervention can control pain in emergency department patients whose providers feel the need for additional pain medication. The main questions it aims to answer are:

  • Does oral ketamine result in a different mean change in pain scores compared with oral oxycodone?
  • Is there a difference in the need for additional opioid administration within 24 hours after the initial dose of study medication (oral ketamine vs oral oxycodone)?

Researchers will compare oral ketamine to oral oxycodone to see if there is a difference in pain control or the need for additional opioid administration.

Participants will:

  • Fill out a survey prior to study medication administration assessing pain scores, pain presentation, and medication history
  • Be randomized to and receive a dose of oral ketamine or oral oxycodone as the study medication for pain control
  • Fill out a survey assessing pain control, side effects, and safety outcomes
  • Receive follow-up phone calls at 1 and 3 months after enrollment to assess pain and opioid use

Conditions

Detailed Description

In an effort to combat the ongoing opioid crisis, healthcare providers continue to search for alternatives to opioids that are both safe and effective. While no medicine has an ideal profile, oral ketamine have attributes that may serve emergency department (ED) patients well when dealing with painful conditions. While IV ketamine has been well-studied in the ED setting and oral ketamine has been studied in the post-operative setting, there is limited data describing the safety and effectiveness of oral ketamine in the ED setting. Guided by colleagues from the Anesthesia Acute Pain Service, the Albany Medical Center (AMC) ED has begun giving oral ketamine to appropriate ED patients with painful conditions. We aim to conduct a pilot, un-blinded randomized controlled trial to compare the benefits and detriments of oral ketamine vs. oxycodone in ED patients who require 'second line' pain medicine.

A convenience sample of emergency department patients will be randomized to receive either:

Oxycodone arm:

o The treating provider will order oral oxycodone 5 mg times one

or

o The treating provider has made a deliberate decision that the patient requires (because of weight, prior exposures, etc.) greater than oxycodone 5mg times one

Oral ketamine arm:

o The treating provider will order ketamine 0.75 mg/kg oral times one (max 80mg)

Outcomes measured

Participants will be assessed for

  • Pain scores at 30 and 60 minutes after either study drug administration
  • Whether they received opioids at 6 hours, 12 hours, and 24 hours after receiving either study drug
  • For admitted patients, whether they received opioids upon admission to the hospital, and whether they were discharged with a prescription for opioids
  • Whether the participation has received opioid pain medicines, ketamine, or other recreational drugs during the one month after enrolling in the study
  • Whether the participation has received opioid pain medicines, ketamine, or other recreational drugs during the three months after enrolling in the study

We will calculate a difference in change in mean pain scores before and after the intervention in each study arm. We will also compare morphine milli-equivalents use during the time intervals above, as well as usage of opioids, ketamine, and recreational drugs during the one month and three month period after enrollment.

Because this is a pilot study, we have not calculated an effect size.
