Abstract
Introduction. Asthenia manifestation treatment is an urgent problem due to its high frequency in outpatients.Аim. To evaluate in a controlled randomized clinical trial the efficacy and tolerability of the course use of a combination of pyridoxine and glutamic acid in patients with asthenic complaints.Materials and methods. 50 outpatients with main asthenia manifestations were included in the study if they complied inclusion criteria and signed the informed consent. After randomization, in group 1 a combined supplement with 2.5 mg of pyridoxin and 100 mg of glutamic acid (Metabovit® Life Energy, MNPK “BIOTIKI”) was added to therapy 1 tablet a day sublingually, in group 2 patients received basic therapy for chronic diseases only. The duration of observation was 21 days. Before and after the end of the study all patients underwent neuropsychological examination, which included the questionnaires: Multidimensional Fatigue Inventory (MFI-20), a Reader stress test (adopted by O.Kopina), a questionnaire on the level of life exhaustion (The Maastricht Questionnaire), a “Schulte tables” test with working efficiency evaluation.Results. In the group of patients receiving Metabovit® Life Energy 1 tablet a day, in comparison with the control group (p < 0.001) the overall score on the MFI-20 self-questionnaire decreased and amounted to 29 [26; 30]; Δ MFI-20 was equal to -22 [-27; -16]; the results reached normative values for most participants; improved time the performance of the “Schulte tables” test decreased by more than 9 seconds; stress levels decreased by almost 30% in men and 20% in women; the indicator of life exhaustion decreased by 60%. In patients in the control group, no significant changes in the studied indicators were detected by the end of the follow-up.Conclusion. In the group of patients who received the biologically active food supplement Metabovit® Life Energy, there was a significant positive dynamics and regression of most of the symptoms of asthenia, in comparison with the control group.
