Cytoflavin in the Rehabilitation of Post-intensive Care Syndrome in Stroke Survivors

Use of Cytoflavin Solution at the Time of Early Rehabilitation in Patients With Post-intensive Care Syndrome Who Underwent Ischemic Stroke

Objective - to assess the effect of Cytoflavin® and its tolerability within the integrated program of rehabilitation of patients who underwent ischemic stroke

Study Overview

• Status: Completed
• Conditions: Ischemic Stroke; Post Intensive Care Unit Syndrome

Detailed Description

Cerebral stroke (CS) remains one of the key issues of modern society, being a predominant cause of deep and persistent disability of the population. Huge social and economic damage arising from cerebrovascular diseases raises the problem of improving medical care for strokes among the most relevant scientific and practical tasks of neurology Regulation of energy metabolism is considered a powerful tool for acute conditions relief, including those that occur due to acute impairment of cerebral blood flow. A number of adjuvant energy protector concomitant medications with systemic pharmacodynamic properties based on signaling (hormonal) and substrate mode of action of succinic acid and other mitochondrial substrates and co-factors was created for this A significant role in the rehabilitation of patients who underwent CS is assigned to the treatment of complications of care in the intensive care unit, the so-called post-intensive care syndrome (PICS), which is a set of somatic, neurological, social and psychological consequences of periods in intensive care unit (ICU) conditions that bring limitations to the patient's daily activities In the Brain Institute Clinic (Ekaterinburg), the first results of the metabolic status monitoring during physical and cognitive exercise in patients with PICS were obtained. These results prove that control over metabolic state holds the promise of developing approaches to increasing exercise tolerance Taking into account the effectiveness of Cytoflavin® in treatment of acute impairment of cerebral circulation and consequences of cerebrovascular diseases, on the one hand, and its classification as a metabotropic energy corrector, on the other hand, the evaluation of Cytoflavin® medication tolerability in the integrated program of neurorehabilitation of patients with PICS after ischemic stroke presents a significant interest.
