[Effectiveness of Anvifen in the treatment of insomnia in elderly patients]. / Effektivnost' preparata Anvifen pri lechenii insomnii u pozhilykh patsientov.

OBJECTIVE: Purpose of the study to determine the effectiveness of Anvifen in the case of insomnia and meteosensitivity as comorbid stress-induced disorders. MATERIAL AND METHODS: 67 patients aged 60-70 years were examined, who were randomly divided into two groups: group 1 - 33 patients (20 men, 13 women), group 2 - 34 patients (19 men, 15 women). The average age of group 1 was 62.7 [61; 65] years, group 2 was 63.1 [60; 66] years (p=0.28). Research methods: questionnaire for scoring subjective characteristics of sleep, assessing the influence of meteosensitivity on daily activity using a numerical rank scale (NRS) for the previous three months. Patients in group 1 took Anvifen 250 mg (capsules) in the morning and afternoon, 500 mg (2 capsules) in the evening at 10 p.m., and upon awakening at night - an additional 250 mg of the drug per capsule. Patients in group 2 took Anvifen powder (extracting it from the capsule) 250 mg in the morning and afternoon, 500 mg in the evening at 10 p.m., and upon awakening at night - an additional 250 mg of the drug. The time from the nightly intake of Anvifen to the onset of sleep was also assessed on a three-degree scale: «fast¼, «long¼, «very long¼. The duration of treatment was 4 weeks. RESULTS: Baseline results of measured parameters did not differ significantly between groups. After completion of treatment, the total score of subjective sleep characteristics improved in 1st (p=0.00001) and 2nd (p=0.000001) groups. Significant differences from group 1 for the better in group 2 were in «quality of sleep¼ (p=0.00027) and «quality of awakening¼ (p=0.00001). Weather sensitivity decreased in 1st (p=0.00001) and 2nd (p=0.000001) groups. CONCLUSION: Anvifen showed good effectiveness in the treatment of two comorbid conditions of elderly people - insomnia and meteosensitivity. Using the drug in powder form allows you to get a faster and better effect without side-effects.

[Efficacy of potassium N-acetylaminosuccinate (Cogitum) in the treatment of asthenic syndrome: results of double-blind placebo-controlled trial]. / Effektivnost' kaliya N-atsetilaminosuktsinata (Kogitum) pri lechenii astenicheskogo sindroma: rezul'taty dvoinogo slepogo platsebo-kontroliruemogo issledovaniya.

OBJECTIVE: Study of the effectiveness of monotherapy with potassium N-acetylaminosuccinate (Cogitum) for asthenic syndrome (fatigue) in individuals, uncharacteristic somatic, neurological diseases, anxiety disorders, depression and other diseases that may interfere with asthenia. MATERIAL AND METHODS: Patients with fatigue scores of 22 or more on the Fatigue Assessment Scale (FAS) were randomly divided into the main group (MG) - 37 people, mean age 22 years [21; 24] and the control group (CG) - 34 people, mean age 21 years [19; 23]. The Trail Making Test (TMT-A and TMT-B), the assessment of general well-being on a visual analogue scale (VAS), where 0 is the worst state of health, 10 is the state of absolute well-being, was assessed. MG patients received a solution of potassium N-acetylaminosuccinate (Cogitum) 750 mg per day in a sterile container, CG patients received sterile water with banana flavor in a sterile container. The duration of the study was 21 days. RESULTS: Prior to the start of the study, there were no statistically significant differences in FAS, TMT, and VAS between MG and CG. After 21 days, the FAS score in the MG decreased (p=0.00001), the time of TMT-A (p=0.000012) and TMT-B (p=0.000033) decreased, the VAS score increased (p=0.00024). There were no statistically significant changes in the CG. Placebo effect was noted in 10 patients of the CG (29.4%). CONCLUSION: Potassium aminosuccinate (Cogitum) at a daily dose of 750 mg and a duration of treatment of 21 days effectively eliminates the symptoms of asthenic syndrome (fatigue), while accompanied by an improvement in complex cognitive functions. The results of our study suggest that fatigue (asthenic syndrome) and cognitive impairment may have a common pathogenetic mechanism - a deficiency of systems in which mediators are N-acetylaspartate and N-acetylaspartylglutamate. Cogitum had no side effects and was well tolerated. Cogitum is superior to placebo in the treatment of fatigue (asthenic syndrome).

[The effectiveness of short and prolonged course treatment of anxiety with Anvifen]. / Effektivnost' korotkogo i prolongirovannogo kursovogo lecheniya trevozhnogo rasstroistva preparatom Anvifen.

OBJECTIVE: To determine the effectiveness of the treatment of anxiety disorder with Anvifen (aminophenylbutyric acid) in a short (21 days) and prolonged (60 days) course of treatment. MATERIAL AND METHODS: Patients were randomly divided into two groups: a short course (21 days) of treatment with Anvifen (group 1) and a prolonged course (60 days) of treatment with Avifen (group 2). In each group, patients were divided into age subgroups: 20-40 years old (1a - n=30, mean age 32 [21; 39], 2a - n=30, mean age 33 [23; 38] years) and 41-70 years (1b - n=30, mean age 62 [51; 67] years; 2b - n=30, mean age 60 [51; 68] years). Evaluated by: Hospital Anxiety and Depression Scale (HADS); fatigue according to the Russian version of the fatigue assessment scale (The Fatigue Assessment Scale - FAS); sleep assessment according to the questionnaire for scoring the subjective characteristics of sleep (sleep assessment - OS); mean frequency per month of attacks meeting the criteria for a panic attack (PA) in the previous 6 months; a comprehensive assessment of the severity of all subjective symptoms on a 10-point numerical rank scale (NRS), where «0¼ corresponded to the complete absence of any significant subjective symptoms, «10¼ - the maximum degree of bodily and mental discomfort presented by the patient. Anvifen patients took at a dose of 500 mg three times a day. The evaluation of the studied parameters was carried out at the point «1¼ (before the start of treatment), at point «2¼ at the end of the course of treatment (for group 1 - on the 21st day of treatment, for group 2 - on the 60th day of treatment), at point «3¼ (30 days after the end of treatment for patients in both groups). RESULTS: The indicators of subgroups 1a and 1b at point 2 had a significant positive trend (p<0.05) compared with the indicators at point 1, but at point 3 these indicators did not differ significantly (p>0.05). The indicators of subgroups 2a and 2b at point 2 had a significant positive trend (p<0.05) compared with the indicators at point 1, and these differences persisted at point 3 (p<0.05). CONCLUSION: Anvifen effectively eliminates anxiety symptoms, but the effect of a short course lasts less than 1 month, the effect of prolonged treatment lasts more than 1 month. The authors recommend prolonged treatment of anxiety with Anvifen for at least 2 months.

OBJECTIVE: To determine the significance of anxiety disorder and comorbid disorders in patients with post-covid brain fog, to determine the effectiveness of the GABAergic nootropic drug with an anxiolytic effect - Anvifen. MATERIAL AND METHODS: 92 post-COVID-19 patients with no organic brain damage who complain of brain fog 12 weeks after the onset of COVID-19 symptoms. Group 1 (n=40; 43.4±4.5 years) were treated at home; group 2 (n=32; 44.9±5.5 years) were treated in a hospital without oxygen support; group 3 (n=20; 45.1±4.8 years) were treated in a hospital with oxygen support. Assessment scales: Hospital Anxiety and Depression Scale (HADS), Montreal Cognitive Assessment Scale (MoCA); Trail Making Test part B (TMT-B); a scoring questionnaire for the subjective characteristics of sleep; Fatigue Assessment Scale (FAS), 36-Item Short Form Survey (SF-36). According to the indicated scales, no statistically significant differences were found between the groups, therefore, the data of all patients were combined into one group, the indicators were compared before and after treatment (Anvifen 500 mg three times a day for 21 days). RESULTS: Results before/after treatment: HADS anxiety 10.5 [8.5;12]/7 [5;8] (p=0.000025); HADS depression 5 [4; 7] / 4 [4; 6] (p=0.00003); MoCA 22 [21; 22] / 25 [24; 26] (p=0.00001); TMT-B 281 [279; 290] sec / 231 [220; 236] sec (p=0.00001); FAS 27 [23; 31] / 20 [23; 31] (p=0.00001); questionnaire for scoring the subjective characteristics of sleep 15 [15; 16] / 25 [25; 26] (p=0.00001); SF-36 Physical Health 43.8 [42.3; 47.4] / 53.8 [52.3; 20] (p=0.00001); SF-36 Mental Health 34 [32.5; 35] / 47 [45.5; 48] (p=0.00001). CONCLUSION: The authors conclude that anxiety disorder and asthenia play an important role in the pathogenesis of post-COVID brain fog syndrome. Anvifen effectiveness is considered from the point of view of the participation of GABAergic structures in the pathogenesis of the phenomenon under study.
