Comparative efficacy and acceptability of psilocybin-ketamine and typical antidepressants for major depressive disorder management: a network meta-analysis

DELOS Desarrollo Local Sostenible December 11, 2025 Pedro Rodrigues, Weliton Rodrigues Dos Santos Júnior, Ivan de Sousa Araújo et al.

A systematic review and network meta-analysis of 149 randomized controlled trials compared psilocybin, ketamine, and several common antidepressants (escitalopram, bupropion, paroxetine, fluoxetine, sertraline, venlafaxine) against placebo for major depressive disorder. All antidepressants were more effective than placebo, but psilocybin and ketamine achieved the lowest depressive symptom scores and reduced suicidal ideation. For acceptability (measured by dropout rates), placebo outperformed all drugs; however, among the medications, psilocybin had the highest combined ranking for efficacy and acceptability, followed closely by ketamine. The authors suggest these two agents may aid physicians in therapeutic decision-making, including for treatment-refractory depression.

The psychedelic resurgence: Opportunities for behavioral and mental wellness and theory development

European Health Psychologist August 25, 2025 Talea Cornelius, Jorge Encantado, Laura Lopes de Carvalho et al.

Psychedelic treatments show promise for improving health and well-being. This article summarizes the history of early psychedelic research and its recent renaissance. Observational studies have linked psychedelic use to healthier diet, lower rates of heart disease, and spontaneous positive changes in health-related outcomes. The importance of understanding mechanisms underlying psychedelic impacts was emphasized, as was the need for attention to the social context of psychedelic experiences. Evidence for differential impacts of psychedelic use with versus without a partner, and impacts on close relationships, was presented.
