Phase: Phase 4
Study type: Interventional
Primary purpose: Treatment
Allocation: Randomized

Summary:

      The purpose of this study is to obtain additional data on efficacy and safety of Divaza for
      adjustment of oxidative disorders in patients with cerebral atherosclerosis.

      It is assumed that the inclusion of the drug Divaza in the basic therapy will help reduce the
      severity of cognitive disorders, other clinical symptoms of cerebral atherosclerosis, reduce
      the impact of the disease on the quality of life of the patient.

      Participate in the study may be patients with a diagnosis of "cerebral atherosclerosis",
      which, against the backdrop of basic therapy with constant doses of drugs (within the last 4
      weeks), to achieve a stable course of cerebral atherosclerosis, cognitive disorders without
      significant disability are detected.
