Psychedelic therapy showed no clear advantage over openly given antidepressants
Across depression trials, symptom improvement did not differ significantly between psychedelic therapy and traditional antidepressants given openly.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
This abstract-based review found no clear evidence that psychedelic-assisted therapy improved depression scores more than traditional antidepressants given openly. The comparison used changes within separate trial arms, so it does not establish that the treatments are equivalent or interchangeable. It addresses a specific question about symptom improvement when treatment awareness may influence results.
The analysis compared changes across separate trials. The abstract does not provide treatment durations or adverse-event results, limiting assessment of sustained benefit and safety.
What researchers found
Difference in depression-score improvement
17-item Hamilton Depression Rating Scale, baseline to each trial's primary endpoint; estimate favored open-label antidepressants over psychedelic therapy (P = .73).
Why treatment awareness mattered
Researchers focused on whether knowing which treatment was received could influence depression outcomes. They compared psychedelic therapy with openly administered antidepressants and also examined differences between blinded and open-label trial results.
How to read the comparison
The main estimate was uncertain and compatible with differences in either direction. Open-label antidepressant trials showed greater improvement than blinded antidepressant trials; the corresponding comparison for psychedelic therapy did not reach statistical significance.
