The disease is characterized by keratinocyte hyperproliferation, neovascularization, and chronic inflammation with systemic manifestations. A significant proportion of patients, particularly those with moderate-to-severe disease, require systemic therapy. Traditional systemic drugs, including methotrexate, cyclosporine, and acitretin, have proven effective; however, their use may be limited by the development of toxic effects, notably hepatotoxicity, nephrotoxicity, and oxidative stress, which reduces patient compliance.</p> <p>In recent years, particular attention has been given to dimethyl fumarate, an oral immunomodulator belonging to the fumaric acid esters, which possesses anti-inflammatory, antioxidant, and immunoregulatory properties. Dimethyl fumarate is a simple α, β-unsaturated organic small molecule with a highly electrophilic character. Dimethyl fumarate activates the transcription factor Nrf2, promotes the differentiation of regulatory T cells (Tregs), and suppresses pathologically significant Th1 and Th17 responses, thereby targeting key pathogenesis pathways of psoriasis.</p> <p>Randomized clinical trials and real-world clinical practice data demonstrate the high effectiveness of dimethyl fumarate in the treatment of moderate psoriasis, including its effect on difficult-to-treat localizations (scalp, nails, palmoplantar areas), as well as a favorable safety profile with long-term use. The most common adverse events (gastrointestinal disorders, flushing, and lymphopenia) are transient and can be readily managed. Unlike biological disease-modifying antirheumatic drugs, dimethyl fumarate does not require parenteral administration and is associated with a lower risk of severe infectious complications. In 2025, a dimethyl fumarate–based drug was approved for the first time in the Russian Federation (30 mg and 120 mg).</p> <p>This review summarizes current data on the pathogenetic mechanisms of action of dimethyl fumarate in psoriasis, its clinical effectiveness, and safety profile in the treatment of this disease.</p></abstract><trans-abstract xml:lang="ru"><p>Псориаз представляет собой хроническое иммуновоспалительное заболевание кожи мультифакторной природы с выраженной генетической предрасположенностью и поражает около 1–2% населения стран мира. Заболевание характеризуется гиперпролиферацией кератиноцитов, неоваскуляризацией и хроническим воспалением с системными проявлениями. Значительной доле пациентов с псориазом, особенно со средней и тяжёлой степенью течения, требуется назначение системной терапии. Традиционные системные препараты, включая метотрексат, циклоспорин и ацитретин, обладают доказанной эффективностью, однако их применение может быть ограничено развитием токсических эффектов, в частности гепатотоксичности, нефротоксичности и оксидативного стресса, что снижает приверженность пациентов лечению.</p> <p>В Европейских рекомендациях среди системных препаратов первой линии для лечения псориаза фигурирует пероральный иммуномодулирующий препарат на основе диметилфумарата-диметилового эфира фумаровой кислоты, обладающего противовоспалительными, антиоксидантными и иммунорегуляторными свойствами. Диметилфумарат представляет собой α, β-ненасыщенную органическую малую молекулу с высокоэлектрофильным характером. Диметилфумарат модулирует иммунологические нарушения при псориазе, подавляет патологическую васкуляризацию, подавляет гликолиз (феномен Варбурга), который поддерживает избыточную пролиферацию и активность иммунных клеток, что обеспечивает воздействие на ключевые звенья патогенеза псориаза.</p> <p>Результаты рандомизированных клинических исследований и данные реальной клинической практики демонстрируют высокую эффективность диметилфумарата в лечении псориаза умеренной степени тяжести, включая поражение трудных локализаций (волосистая часть головы, ногти, ладонно-подошвенная поверхность), а также благоприятный профиль безопасности при длительном применении. Наиболее частые нежелательные явления (желудочно-кишечные расстройства, приливы и лимфопения) носят преходящий характер и управляемы. В отличие от генно-инженерных биологических препаратов, диметилфумарат не требует парентерального введения и связан с меньшим риском тяжёлых инфекционных осложнений. В 2025 году в Российской Федерации впервые зарегистрирован препарат на основе диметилфумарата 30 мг и 120 мг.</p> <p>Настоящий литературный обзор обобщает современные данные о механизмах патогенетического действия диметилфумарата, его клинической эффективности и профиле безопасности при лечении псориаза.</p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriasis</kwd><kwd>dimethyl fumarate</kwd><kwd>review</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориаз</kwd><kwd>диметилфумарат</kwd><kwd>обзор</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rendon A, Schäkel K.
