The specialized Lidose modified-release technology has improved isotretinoin absorption in the gastrointestinal tract, increasing its bioavailability by 20%, thereby allowing a 20% dose reduction without compromising therapeutic efficacy.</p> <p><bold>Aim:</bold> The work aimed to estimate the clinical outcomes of isotretinoin Lidose in the treatment of moderate to severe acne.</p> <p><bold>Methods:</bold> A retrospective, uncontrolled, single-center study analyzed 2477 cases of systemic isotretinoin prescription in patients with moderate to severe acne, including 1912 women (77.2%) and 565 men (22.8%), with a mean age of 22.7 years; 290 patients (11.7%) had comorbidities. The daily therapeutic dose was calculated based on 0.4–0.8 mg/kg body weight, with a cumulative dose of 100–150 mg/kg. All patients underwent laboratory testing (complete blood count and biochemistry) before treatment, at 3 months, and at the end of therapy. For one month before systemic isotretinoin treatment, throughout the entire treatment course, and for one month after completion, female patients were advised to use at least one (preferably two) effective contraceptive method, including barrier contraception.</p> <p><bold>Results:</bold> After 6–12 months, all patients achieved complete clinical remission. By the end of therapy, skin oiliness and comedones disappeared, inflammatory lesions completely resolved, and skin texture became even. Among adverse events, cheilitis and xerosis were most frequently observed by weeks 2–3 and were successfully managed with moisturizers and lip balms. Transient elevations in transaminases and total cholesterol (within 10% of the normal range) were observed in 3.4% of cases, not requiring dose adjustment.</p> <p><bold>Conclusion:</bold> Systemic isotretinoin administration for moderate to severe acne allows achieving long-term clinical remission, which leads to a positive effect in preventing acne-related emotional distress. Retrospective analysis of isotretinoin Lidose use in clinical practice confirms not only its good tolerability but also its high efficacy in the treatment of moderate to severe acne.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Для лечения среднетяжёлой и тяжёлой степени акне рекомендован системный изотретиноин. Специальная технология модифицированного высвобождения Lidose позволила увеличить усвояемость изотретиноина в пищеварительном тракте, увеличив его биодоступность на 20%, благодаря чему стало возможным снизить дозу принимаемого пациентом изотретиноина на 20% без ущерба его терапевтической эффективности.</p> <p><bold>Цель исследования</bold> ― оценка клинической эффективности и безопасности применения изотретиноина Lidose в терапии среднетяжёлых и тяжёлых форм акне.</p> <p><bold>Методы.</bold> В ретроспективном неконтролируемом одноцентровом исследовании проанализировано 2477 случаев назначения системного изотретиноина пациентам с акне тяжёлой и среднетяжёлой степени, в числе которых женщин 1912 (77,2%), мужчин 565 (22,8%), средний возраст 22,7 года, 290 (11,7%) имели сопутствующие заболевания. Суточная терапевтическая доза рассчитывалась исходя из диапазона 0,4–0,8 мг/кг массы тела и курсовой дозы препарата 100–150 мг/кг. Перед началом лечения, спустя 3 месяца и по окончании терапии все пациенты проходили обследование (клинический, биохимический анализ крови). В течение месяца до начала лечения системным изотретиноином, во время всего курса лечения и в течение месяца по окончании терапии пациенткам также было рекомендовано использовать не менее одного (предпочтительно два) эффективного метода контрацепции, включая барьерный.</p> <p><bold>Результаты.</bold> Через 6–12 месяцев у всех пациентов была достигнута полная клиническая ремиссия. К концу терапии исчезли сальность кожи и комедоны, полностью разрешились воспалительные элементы, наблюдалось выравнивание рельефа кожи. Среди нежелательных явлений, чаще к концу 2–3-й недели, отмечались хейлит и ксероз, с которыми успешно справлялись с помощью увлажняющих кремов и стиков для губ. В 3,4% случаев отмечено транзиторное повышение трансаминаз, общего холестерина (не более 10% от нормы), не потребовавшее коррекции дозового режима препарата.</p> <p><bold>Заключение.</bold> Назначение системного изотретиноина при лечении акне тяжёлой и среднетяжёлой степени позволяет достичь у пациентов длительной клинической ремиссии, что обусловливает положительный эффект в профилактике психотравмирующих состояний, связанных с акне. Ретроспективный анализ результатов применения изотретиноина Lidose в клинической практике подтверждает не только его хорошую переносимость, но и высокую эффективность в терапии среднетяжёлых и тяжёлых форм акне.</p></trans-abstract><kwd-group xml:lang="en"><kwd>acne</kwd><kwd>systemic isotretinoin</kwd><kwd>acne severity</kwd><kwd>daily dose</kwd><kwd>cumulative dose</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>акне</kwd><kwd>системный изотретиноин</kwd><kwd>степень тяжести акне</kwd><kwd>суточная доза</kwd><kwd>курсовая доза</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">ООО «ЯДРАН»</institution></institution-wrap><institution-wrap><institution xml:lang="en">JADRAN LLC</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Dreno B, Poli F.
