Research Interests

  • Pharmacology of Hyperbaric Oxygen (HBO2) Suppression of Chronic Pain and Opiate Withdrawal

HBO₂ therapy has been approved by the FDA for a limited set of clinical indications, although there are clinical reports that HBO₂ therapy appears to be effective in a broader range of conditions, including several examples of chronic pain. We have demonstrated that HBO₂ therapy causes relief of acute pain and gathered convincing evidence that HBO₂ therapy activates antinociceptive pathways in the brain. Further research showed that HBO2 therapy could also relieve neuropathic pain in animal models of chronic pain.  Evidence of an opioid mechanism of HBO2 led to the finding that treatment with HBO2 could   suppress naloxone-precipitated opiate withdrawal in morphine-dependent mice. More recently, we have concluded a clinical study in Spokane. Subjects enrolled in a methadone maintenance program agreed to a 10% reduction in their daily methadone dose so that there was less protection against opioid withdrawal.  HBO2 therapy administered for several days following methadone dose reduction resulted in reduced intensity of opioid withdrawal signs, a prolonged reduction in the methadone dose needed to reduce withdrawal, and improvement in quantity and quality of sleep.  HBO2 therapy may potentially be an innovative approach to the treatment of chronic pain and opioid dependence.
