INTRODUCTION: Although the cause of amyotrophic lateral sclerosis (ALS) is unknown, excitotoxicity mediated by glutamate has been implicated. Dextromethorphan is a NMDA-glutamate receptor antagonist with neuroprotective properties.MATERIAL AND METHODS: The effect of treatment with dextromethorphan (150 mg daily) in ALS patients was evaluated in a randomized, double-blind, placebo-controlled study. Forty-five patients were included in the analysis.RESULTS: At the end of the treatment period, 12 months after randomization, 15 patients (65%) in the placebo group and 12 patients (55 %) in the dextromethorphan group were still alive (log rank test, P=0.49). Rates of disease progression, as expressed by rates of decline in pulmonary function and in functional disability, were similar in both groups except for a significantly less pronounced rate of decline in the ability scores for the lower extremities in the dextromethorphan group.CONCLUSION: Treatment with a relatively low dose of dextromethorphan did not result in an improvement in 12-month survival in ALS. |
