A Study to Select the Dose and Evaluate the Effectiveness and Safety of the Drug Refralon®, Tablets, 1 mg for Long-term Use to Prevent Recurrence of Atrial Fibrillation/Flutter After Terminating Its Persistent Form

Summary

Refralon® tablets in two different doses (1 or 2 tablets per day) will be evaluated vs. placebo in patients with persistent atrial fibrillation/flutter after synus rhythm restoration in order to prevent recurrence of arrhythmia. Efficacy and safety of Refralon® tablets will be studied, its optimal dose will be selected and its pharmacokinetics will be evaluated in 14 days, 1, 3 and 6 months.
