Метформин как препарат для адъювантной терапии заболеваний центральной нервной системы
ИННОВАЦИОННАЯ ФАРМАКОЛОГИЯ
Аннотация
В статье обобщены современные данные о нейропротекторных свойствах метформина при заболеваниях центральной нервной системы. Основное внимание уделено механизмам действия через активацию 5’АМФ-активируемой протеинкиназы (AMPK), модулирующей энергетический метаболизм, аутофагию, нейровоспаление и окислительный стресс. Рассмотрены доклинические исследования, демонстрирующие снижение патологииα-синуклеина при болезни Паркинсона, уменьшение накопленияβ-амилоида при болезни Альцгеймера и иммуномодуляцию при рассеянном склерозе. Клинические данные демонстрируют противоречивые результаты — часть работ указывает на улучшение когнитивных/двигательных функций, другие не подтверждают значимых эффектов. Подчеркивается необходимость масштабных рандомизированных исследований для оценки роли метформина как адъювантной терапии, учитывая зависимость эффектов от дозы, длительности лечения и популяционных особенностей.
