This systematic review and meta-analysis aimed to identify sleep-related abnormalities associated with...

The therapeutic effects of psychedelics for opioid use disorder: A systematic review of clinical studies.

Psychiatry Research June 1, 2025 Jeremy Weleff, Alejandra Pulido-Saavedra, Ardavan Mohammad Aghaei et al. 4 citations

Opioid-related overdose deaths have reached record high levels, and novel treatments for opioid use disorder (OUD) are needed. The three United States Food and Drug Administration (FDA)-approved medications for OUD function primarily at the mu-opioid receptor. While these remain the gold-standard treatment for OUD, they have shortcomings and treatment options separate from the opioid receptor...

The potential of non-psychedelic 5-HT2A agents in the treatment of substance use disorders: a narrative review of the clinical literature.

Expert Opinion on Pharmacotherapy February 1, 2025 Alejandra Pulido-Saavedra, Anna Borelli, Razi Kitaneh et al.

Substance use disorders (SUDs) are a public health issue, with only some having FDA-approved indicated treatments and these having high attrition. Consequently, there has been interest in novel interventions (e.g. psychedelics that target 5-HT2A receptors) with some promising results. In this narrative review, we aim to focus on the role of the 5-HT2A receptors on the effectiveness of the...

Effects of psychedelics on opioid use disorder: a scoping review of preclinical studies.

Cellular and molecular life sciences : CMLS January 21, 2025 Alejandra Pulido-Saavedra, Henrique Nunes Pereira Oliva, Tiago Paiva Prudente et al. 5 citations

The current opioid crisis has had an unprecedented public health impact. Approved medications for opioid use disorder (OUD) exist, yet their limitations indicate a need for innovative treatments. Limited preliminary clinical studies suggest specific psychedelics might aid OUD treatment, though most clinical evidence remains observational, with few controlled trials. This review aims to bridge...

The contribution of psychotherapy in potential therapeutic effects of psychedelics for treatment of opioid use disorder.

Current Addiction Reports 2025 Anahita Bassir Nia, Yalda Farahmand, Garret Griffith et al.

Despite national efforts to curb the opioid crisis, the clinical and societal challenges continue to grow. FDA-approved medications for opioid use disorder (OUD) are effective but are associated with high rates of treatment discontinuation and relapse. A collection of agents with acute effects on consciousness, collectively (if variably) categorized as 'psychedelics', have emerged as potential...

Changes in synaptic markers after administration of ketamine or psychedelics: a systematic scoping review

Frontiers in Psychiatry June 26, 2023 Simon Zhornitsky, Henrique Nunes Pereira Oliva, Laura A. Jayne et al. 12 citations

Background Ketamine and psychedelics have abuse liability. They can also induce “transformative experiences” where individuals experience enhanced states of awareness. This enhanced awareness can lead to changes in preexisting behavioral patterns which could be beneficial in the treatment of substance use disorders (SUDs). Preclinical and clinical studies suggest that ketamine and psychedelics...
