Australian government approval has been granted for 3,4-methylenedioxy-methamphetamine (MDMA) treatment of post-traumatic stress disorder and psilocybin for treatment-resistant depression, but the process of translating psychedelic-assisted therapies (PAT) into more widespread use is complex. Along with establishing the efficacy and feasibility of PATs, their acceptability amongst consumers is a crucial factor of successful implementation. This study utilised the Theory of Planned Behaviour to evaluate the acceptability of PATs amongst mental health consumers, identifying potential influences of these attitudes and predictors of PAT uptake.

Introduction: Methamphetamine use disorder is a global public health concern with no approved pharmacotherapies for its treatment. One recent randomised controlled trial conducted in the USA examined a combination of bupropion and naltrexone not readily available globally. Here, we report a trial protocol for an oral formulation of combined naltrexone and bupropion.

Background: Preclinical studies have demonstrated that cannabidiol (CBD) reduces alcohol-seeking behaviors and may have potential for managing alcohol use disorder (AUD). In this study, we examined the effects of CBD versus placebo on (i) psychophysiological, craving and anxiety responses to alcohol and appetitive cues; (ii) tolerability measures including cognitive functioning.

Methods: Twenty-two non-treatment-seeking individuals with AUD (DSM-5) participated in a cross-over, double-blind, randomized trial, receiving either 800 mg of CBD or matched placebo over 3 days.

Rationale: Both topiramate and naltrexone have been shown to affect neural alcohol cue reactivity in alcohol use disorder (AUD). However, their comparative effects on alcohol cue reactivity are unknown. Moreover, while naltrexone has been found to normalize hyperactive localized network connectivity implicated in AUD, no studies have examined the effect of topiramate on intrinsic functional connectivity or compared functional connectivity between these two widely used medications.

Article Synopsis
  • - Topiramate has shown effectiveness in reducing alcohol use and possibly lowering anxiety severity in patients with alcohol use disorder (AUD), compared to naltrexone, another medication used for AUD.
  • - In a study with 42 treatment-seeking AUD patients, participants were given either topiramate or naltrexone for 12 weeks, and their neural responses to an anxiety-inducing task were measured using fMRI after 6 weeks of treatment.
  • - The study found no major differences in brain activation between the two treatment groups, but it noted that changes in anxiety levels were linked to the brain's response to threat cues, providing insights into how these medications may work.
