Pilot Study Launched of Ketamine Tablet as Pain Reliever
/By Pat Anson, PNN Editor
Ketamine has become a trendy alternative treatment for pain, depression, anxiety and post-traumatic stress syndrome (PTSD). But to get it, you’ll need to get a ketamine infusion, injection or nasal spray – usually under strict medical supervision.
But someday you may be able to take a ketamine tablet at home, just like you would most other medications. A pilot study is underway at a New York City hospital to see if an oral formulation of ketamine and aspirin could be a useful treatment for pain.
“For certain patients, ketamine could be a real game changer,” says Dr. Joseph Habboushe, an emergency room physician and founder of Vitalis Pharmaceuticals. “If you look at pain management and what we have available to send patients home with, it’s really limited. We have NSAIDs. We have opiates. We have other things that sedate. It’s a fairly limited in choice.”
Ketamine is not an opioid and does not suppress respiration, making it relatively safe to use. But in high doses, it puts patients into a dissociative, dream-like state -- making it inappropriate for outpatient use.
What Habboushe and his colleagues hope to demonstrate is that a low dose of ketamine, when combined with aspirin, can be an effective and non-addictive pain reliever that can be used safely at home.
Their observational study at Maimonides Medical Center will enroll 25 patients with acute musculoskeletal pain, who will receive 0.5 mg of oral ketamine administered simultaneously with 325mg of aspirin. Pain scores and adverse events will be recorded at various intervals for up to two hours.
The study is being led by Sergey Motov, MD, an emergency room physician who is passionate about finding alternatives to opioids.

"The need for safe and efficacious analgesics in the emergency department and on an outpatient basis is stronger than ever," Motov said in a statement. “Taking a novel approach to orally-administered ketamine has the potential to move physicians one step closer to successfully combatting the nation's ongoing opioid crisis.”
Vitalis has developed a proprietary formulation of aspirin -- called VTS-Aspirin -- that delivers faster and stronger pain relief than traditional aspirin. Preliminary research indicates that combining VTS-Aspirin with low-dose ketamine may boost its potency.
“This is a proof-of-concept study. If we can demonstrate that ketamine will work orally, then it can be used for acute pain, maybe later chronic pain, maybe depression and all the other indications,” Habboushe told PNN. “If we can achieve that, it will be a breakthrough that will absolutely drive a lot of value to patients by reducing opiate need and reducing their pain in a very significant way. And so, it’s worth studying.”
Vitalis is also studying the use of VTS-Aspirin with fumaric acid as a treatment for multiple sclerosis that has fewer side effects. Also undergoing research is a combination of VTS-Aspirin with niacin as a treatment for high cholesterol.
