| Popis: | Background Fatigue is one of the most common symptoms in patients with multiple sclerosis (MS). Currently, there is no approved medication for MS-related fatigue. Objective In this study, we aim to evaluate the safety and efficacy of memantine for improving fatigue in patients with MS. Methods This was a pilot randomized, double-blind, placebo-controlled clinical trial. Eligible patients with relapsing-remitting MS (RRMS) according to the McDonald criteria were randomized to receive either memantine (20 mg/day) or placebo and were assessed at baseline and three months after treatment. The change in the severity of fatigue was determined by the Modified Fatigue Impact Scale (MFIS). Results Sixty-four patients were randomly allocated to the memantine (n = 32) and placebo (n = 32) groups. Sixteen patients in the memantine group and 24 patients in the placebo group completed the study. The mean [95% CI] absolute change in MFIS scores from baseline did not differ significantly between the memantine (−5.8 [−12.7 to 1.0]) and placebo (−4.0 [−10.6 to 2.7]) groups (between-group difference: −1.9 [−11.7 to 7.8], P = .702). No serious adverse events were reported, except for dizziness and sedation in four patients in the experimental arm, which resulted in discontinuation. Conclusion This trial failed to prove any clinical efficacy of memantine for the management of MS-related fatigue. Although memantine was generally well-tolerated, adverse events were among the major causes of dropout in this study. |
