OBJECTIVE: To assess the efficacy and safety of sequential therapy with Mexidol solution for intravenous and intramuscular administration, 50 mg/ml and Mexidol FORTE 250 film-coated tablets, 250 mg in patients with chronic brain ischemia (CBI). MATERIAL AND METHODS: An international multicenter, randomized, double-blind, placebo-controlled trial, conducted in 15 clinical centers located in Russian Federation and Republic of Uzbekistan, included 318 patients with CBI aged 40 to 90 years. The patients were randomized into 2 groups, the patients of the 1-st group received Mexidol intravenously 500 mg once daily for 14 days, followed by Mexidol FORTE 250 - 250 mg 3 times a day orally for 60 days; patients of the 2-nd group received a placebo in a similar mode. The primary endpoint was the mean value of difference by MoCA scale at the point of completing the therapy comparing to initial value. RESULTS: <0.000001). The lower limit of the 95% confidence interval for the difference in the average of the main efficacy endpoint between the 1-st and 2-nd groups was 1.51, which allows to state a higher efficacy of the use of Mexidol. According to the estimates of secondary endpoints, a statistically significant advantage over placebo at the last visit achieved while evaluation by the following scales and tests: digit symbol substitution test, MFI-20 asthenia assessment scale, Beck anxiety scale, Vane questionnaire, Tinetti scale, SF-36 questionnaire (mental component of health), CGI scale. The comparable nature of the safety profile of Mexidol and Placebo was established. CONCLUSION: The validity and expediency of the use of Mexidol and Mexidol FORTE 250 in the treatment of patients with CBI has been demonstrated.
