Pathogenetic therapy of cognitive impairment: results of a multicenter placebo-controlled clinical trial of the efficacy and safety of Miladean

Abstract

Evaluation of the efficacy and safety of the use of the drug Miladean in the treatment of patients with cognitive disorders (CDs) of vascular genesis. In during the double-blind multicenter prospective randomized placebo-controlled phase III clinical trial, 300 patients with CDs and chronic cerebral ischemia were randomized into 3 groups: group 1 (n=100) received Miladean (daily dose: memantine 10 mg + melatonin 6 mg), group 2 (n=101) - memantine (10 mg/day), group 3 - placebo (n=99) for 8 weeks. The dynamics of the overall score (the primary criterion of effectiveness) and the proportion of patients with improvement on the Alzheimer's Disease Assessment Scale-Cognitive (ADAS-Cog), the dynamics of visual-spatial orientation disorders (Benton test), sleep quality (Pittsburgh Sleep Quality Index scale) and the safety of therapy were evaluated. Miladean demonstrated efficacy in the treatment of CDs: a statistically and clinically significant decrease in the overall score on the ADAS-Sod scale was shown (by 6.1 versus 4.7 and 3.5 points in the 2nd (p=0.009) and 3rd (p<0.05) groups) and an increase in the proportion of patients (96.9%) with clinically and statistically a significant improvement compared to the 2nd and 3rd groups (p=0.019 and p<0.001 respectively). Miladean significantly improved the performance in the Benton test (1.20±1.66 vs. 0.64±1.69 points in group 3, p=0.026) and sleep quality (84.7% of patients with CDs), compared to placebo (63.9%) and memantine (64.3%) (p=0.002 in both cases). Miladean was well tolerated, there were no cases of interaction with basic therapy drugs. The combination of many different pathogenetic effects of Miladean suggests that it has the ability to slow down the rate of progression of CDs and stabilize the condition of patients. The unique combination of active substances in Miladean has been proven to be effective and safe in the treatment of patients with CDs.
