Trazodone in neurology, a new life for an old molecule - an updated, comprehensive, systematic review of clinical trials.

INTRODUCTION

The triazolopyridine derivative trazodone is approved for the treatment of major depressive disorder (MDD) in adults; according to the available literature, this molecule, through a specific dose-dependent profile of action, was found to be a potential therapeutic option in some neurological conditions. This systematic review aimed to synthesise the available evidence on the use of trazodone in neurological patients.

METHODS

PubMed was searched for articles published from inception until March 2025. Article reference lists were screened, and relevant articles were retrieved for consultation. Clinical trials specifically investigating trazodone in neurological populations were included, following PRISMA guidelines for systematic reviews.

RESULTS

Out of 69 records initially retrieved, 14 studies met the inclusion criteria, comprising 13 randomised controlled trials and 1 retrospective study, with a total of 608 patients. Most of the included studies focused on individuals with dementia, while others explored its use in different neurological disorders.

CONCLUSIONS

Despite being an older antidepressant, trazodone remains widely prescribed. Beyond treating depression in neurological patients, it may may be useful in the treatment of some neurological aspects. However, current evidence remains limited. Further high-quality research is necessary to better define the therapeutic potential of trazodone in the management of neurological conditions.
