Evaluation efficiency of modern antidepressants by means of quantative pharmaco-EEG

An example perspective way to improve the pharmacotherapy of depression is to combine SSIRs with representatives of other groups of drugs. Great interest from this point of view is the hormone of pineal gland - melatonin (MT), which is an important element of the non-specific antistress system of body. Evaluation efficiency of the above regimes of pharmacotherapy of depressive frustration showed, that the application of valdoxan, and also combination fluoxetine+melaxen favorably affects the course of the disease and contributes to a more rapid normalization of bioelectric activity of brain than fluoxetine in isolation, both experimentally and clinicall

СРАВНИТЕЛЬНАЯ ОЦЕНКА ЭФФЕКТИВНОСТИ ФАРМАКОТЕРАПИИ ДЕПРЕССИВНОГО РАССТРОЙСТВА МЕТОДОМ КОЛИЧЕСТВЕННОЙ ФАРМАКО-ЭЭГ

Timely diagnosis and efficacious pharmacotherapy of depressive disorders are of immediate concern to the medical practice. The quantitative pharmaco-electroencephalography method enables differential evaluation of the affective disorder treatment efficacy. The aim of the study was to perform comparative evaluation of pharmacological  activity of two treatment regimens for moderate somatization disorders in patients with gastrointestinal pathology: monotherapy with fluoxetine — an antidepressant  of the selective serotonin  reuptake  inhibitors  class, and combination  therapy  with melatonin-containing medicine.  Methods: the severity of the depressive disorder and the efficacy of the treatment regimens were assessed using the Hamilton Depression Rating Scale (HDRS-17). The quantitative  pharmaco-electroencephalography (pharmaco-EEG) was used both before and during the treatment to analyse the effect of the medicinal products on the functional state of the brain in the patients with depressive disorder. Results: it was shown that the combination  of fluoxetine and melatonin  results in a more rapid regression of depressive symptoms according to the HDRS-17 scale. The quantitative pharmaco-EEG method helped to reveal specific differences between the effect of fluoxetin as monotherapy and in combination  with melatonin  on the bioelectrical activity on the patients brain. Conclusions: the analysis of the relative power of the patient brain rhythms by pharmaco-EEG demonstrated a more rapid restoration  of normal EEG rhythms in the patients who received the combination  of fluoxetine and melatonin, than in those patients who received fluoxetine monotherapy which did not result in complete remission of the existing depressive episode in a number of patients after the 42-day treatment course.Своевременная диагностика и эффективная фармакотерапия депрессивных расстройств  является  актуальной проблемой в медицинской практике. Метод количественной фармако-электроэнцефалографии позволяет дифференцированно оценить  эффективность лечения  данного  аффективного расстройства.  Цель работы: проведение  сравнительного анализа  фармакологической активности двух схем лечения  соматизированного депрессивного расстройства  средней степени  тяжести у пациентов с патологией  желудочно-кишечного тракта: монотерапии антидепрессантом из группы селективных  ингибиторов обратного захвата серотонина — флуоксетином и его комбинированного применения с лекарственным препаратом, содержащим  мелатонин. Методы: с помощью  шкалы  Гамильтона  (HDRS-17) проводилась оценка  степени  тяжести депрессивного расстройства  у пациентов и эффективности применения обозначенных схем фармакотерапии. Методом  количественной фармако-электроэнцефалографии  (фармако-ЭЭГ),  использовавшимся как до начала лечения,  так и на фоне проведения соответствующего  режима фармакотерапии, осуществлялся анализ влияния вышеуказанных лекарственных средств на функциональное состояние головного  мозга пациентов с депрессивным  расстройством. Результаты: показано, что комбинация флуоксетина с мелатонином способствует  более быстрому регрессу депрессивной симптоматики согласно шкале HDRS-17. Метод количественной фармако-ЭЭГ позволил выявить  характерные  различия  во влиянии флуоксетина при монотерапии или комбинированном применении с мелатонином на биоэлектрическую активность  головного  мозга пациентов. Выводы: проведенный анализ  относительного значения мощности ритмов головного мозга пациентов методом количественной фармако-ЭЭГ показал,  что восстановление нормальных значений ритмов ЭЭГ на фоне комбинации флуоксетина с мелатонином происходит быстрее, чем при монотерапии флуоксетином, прием  которого  не привел  к полной  ремиссии  текущего депрессивного эпизода у ряда пациентов при лечении в течение 42 сут

SURVIVAL ANALYSIS AND SPATIAL-FREQUENCY DISTRIBUTION OF EEG-INDICES IN RATS’ GLOBAL CEREBRAL ISCHEMIA

Research goal was an evaluation of survival and electroencephalographic (EEG) indices in rats with experimental cerebral ischaemia (ECI) during the preventive application of cerebroprotective drugs: nootropics (piracetam (300 mg/ kg/day) and vinpocetine (5 mg/kg/day)) in combination with melaxen (0,25 mg/kg/day). Global CI was modelled by left and right common carotid arteries (CCA) ligation. It was founded that preventive combined application of vinpocetine and melaxen reduced significantly (about 2.5 times (р≤0,01)) rats lethality and influence of circulatory ischemia adverse effects on survived experimental animals brain functional state. Only in the rats receiving these drugs were registered frequency ranges close to the baseline, specifically, theta (θ)-rhythm was dominated over delta (Δ)-activity, indicating waking state of the rats’ brain. The results obtained can be used in clinical practice for prevention and treatment of ischemic brain diseases
