%X Background: Mexiletine is a potential drug in amyotrophic lateral sclerosis (ALS) that has been tested in clinical trials. The objective of this study was to determine the efficacy and safety of mexiletine in ALS via systematic review of existing evidences. Materials & methods: Relevant records were searched using major healthcare electronic databases. Data on functional disability, impairment, survival, muscle cramp frequency and severity, and adverse events were obtained. Results & conclusion: Three relevant randomized controlled trials with 141 patients were included in this review. Mexiletine has no effect on the functional disability, impairment and survival in ALS. However, significant improvement in reducing muscle cramp severity and frequency was shown. The most common adverse effect associated with mexiletine intake among ALS patients are nausea (n = 11, 7.8%) and tremors (n = 5, 3.6%).
