Preadministration of Lorazepam Negates the Long-Term Antidepressant-Like Effects of Psilocybin in Male Wistar Kyoto Rats

Psychedelic Medicine  – December 16, 2025

Summary

Psilocybin demonstrates lasting antidepressant effects, persisting for up to 9 weeks in tested rats. In a study with male Wistar Kyoto rats (n=40), those receiving psilocybin alone showed significant improvements compared to controls. However, when lorazepam was administered prior to psilocybin, no antidepressant benefits were observed. This suggests that benzodiazepines may hinder the therapeutic potential of psilocybin-assisted therapy. Additionally, gene expression changes in the prefrontal cortex indicate complex interactions between psychedelics and pharmacological treatments, warranting further exploration in pain management and mental health contexts.

Exploring Determinants of Psilocybin Acceptance as an Alternative Modality for Major Depressive Disorder: A Pilot Study

Journal of Complementary and Alternative Medical Research  – December 16, 2025

Summary

For young adults with major depressive disorder, perceived benefits are the strongest predictor of accepting psilocybin-assisted therapy (beta = 0.584). Among 33 participants, a model incorporating health beliefs explained 83.9% of the variance in acceptance, significantly up from 25.6% with initial factors. This suggests that emphasizing psilocybin's efficacy can boost acceptance, especially important given 30% of patients are treatment-resistant. Tailored communication strategies are crucial for increasing uptake of novel therapies.
