Ketamine's effects on the body's natural opioid system

Enhancement of the endogenous opioid system by ketamine

['FUNDING_R01'] · ICAHN SCHOOL OF MEDICINE AT MOUNT SINAI · NIH-11323513

This project looks at how a single dose of ketamine changes the brain's natural opioid system in people with depression, chronic pain, or opioid use disorder.

What this research studies

Researchers will examine how ketamine interacts with the body's own opioid peptides and receptors to produce both rapid (minutes to hours) and longer-lasting (days to weeks) effects. The work combines laboratory experiments on opioid receptor function with measurements taken after ketamine exposure to track molecular and functional changes. Findings will link short-term actions to sustained changes that could explain ketamine's benefits for mood and pain.

Who could benefit from this research

Good fit: Ideal participants would include people with treatment-resistant major depressive disorder, chronic pain, or opioid use disorder who might be considered for ketamine-related therapies.

Not a fit: People without these conditions or those who cannot receive ketamine due to medical contraindications are unlikely to benefit directly from participation.

Why it matters

Potential benefit: If successful, this work could point to safer, more targeted treatments for depression, chronic pain, and opioid use disorder by harnessing the body's own opioid system.

How similar studies have performed: Clinical research has shown ketamine can rapidly relieve depression and some pain, but using the opioid system to explain or improve those effects is a newer and still-developing area.
