Efficacy of acetylleucine in vertigo and dizziness: a systematic review of randomised controlled trials.

ABSTRACT

PURPOSE: To assess the efficacy of acetylleucine to improve or stop an attack of vertigo and dizziness (vertigo/dizziness). METHODS: Systematic review by 2 independent reviewers. Consultation of the Medline, Cochrane and ClinicalTrials.gov databases until September 2018. Keywords used Acetylleucine, Tanganil®, Acetyl-DL-leucine, Acetyl-leucine. Trial selection randomised controlled trials (RCTs) comparing acetylleucine against placebo. RESULTS: Up until 2018, no RCTs have been published on the efficacy of acetylleucine in vertigo/dizziness. CONCLUSION: There is no solid evidence of the efficacy of acetylleucine in vertigo/dizziness. Given its frequent prescription and the cost generated for the French social security system, high-quality randomised trials should be carried out to assess its efficacy.
