A retrospective chart review of 128 participants in a 12-week ketamine-assisted group therapy program found that the treatment was well tolerated, with no dropouts. Across 448 sessions, elevated blood pressure occurred after 49.16% of sessions, while nausea affected 12.05% of participant-sessions, vomiting 2.52%, headache 3.35%, and dizziness in seven participant-sessions. Adverse events were transient and resolved with rest or medication. The findings suggest good safety and tolerability for intramuscular and sublingual ketamine dosing in a community group psychotherapy setting.
Chronic pain and post-traumatic stress disorder (PTSD) frequently co-occur and worsen each other. In a Phase 2 open-label trial of MDMA-assisted therapy for PTSD, 84% of 32 participants reported pain and 75% reported pain-related disability. After treatment, those with the highest baseline pain showed significant reductions in pain intensity, disability, and overall severity grade; those with medium baseline pain also showed significant reductions in pain intensity. The findings suggest MDMA-assisted therapy may reduce chronic pain in people with severe PTSD, but the data are preliminary and encourage further research.
