Primary open-angle glaucoma (POAG) is a chronic, progressive eye condition causing optic nerve damage and irreversible vision loss by increasing intraocular pressure (IOP). Therapy primarily aimed at reducing IOP to prevent disease progression. Pharmacoeconomic evaluation of fixed-dose combinations (FDCs) has attracted growing interest in recent years as a strategy to enhance both treatment efficacy and accessibility.</p></sec><sec><title>Objective</title><p>Objective: To review the cost and clinical effectiveness for FDCs of travoprost/timolol (TT) and latanoprost/timolol (LT) for POAG treatment.</p></sec><sec><title>Material and methods</title><p>Material and methods. A systematic literature review was conducted using PubMed/MEDLINE, Web of Science, ScienceDirect, and Google Scholar databases. The sampling included studies evaluating FDCs of TT and LT in terms of its cost and clinical effectiveness, as well as cost-effectiveness and cost-utility ratios.</p></sec><sec><title>Results</title><p>Results. TT-FCD proved to be more cost-effective than LT-FDC in several European countries and the Philippines, resulting in lower long-term costs and slowing the progression of vision loss. Conversely, in China identified LT-FDC was more cost-effective due to lower daily costs. Both FDC options improved patient adherence to treatment due to their simplified administration.</p></sec><sec><title>Conclusion</title><p>Conclusion. TT-FCD may be a more favorable treatment option for POAG in certain regions, considering its pharmacoeconomic and clinical advantages. However, treatment selection should be individualized based on regional healthcare dynamics, medicine pricing, and patient access to medicines.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Актуальность</title><p>Актуальность. Первичная открытоугольная глаукома (ПОУГ) – хроническое прогрессирующее заболевание, характеризующееся повышением внутриглазного давления (ВГД), что может привести к повреждению зрительного нерва и необратимой потере зрения. Основной целью терапии является снижение ВГД для предотвращения прогрессирования патологии. В последние годы растет интерес к фармакоэкономической оценке фиксированных комбинаций (ФК) препаратов как способа повышения эффективности и доступности лечения.</p></sec><sec><title>Цель</title><p>Цель: провести систематический обзор экономической и клинической эффективности ФК «травопрост + тимолол» (ТТ) и «латанопрост + тимолол» (ЛТ) при лечении ПОУГ.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Выполнен систематический обзор публикаций, найденных в базах данных PubMed/MEDLINE, Web of Science, ScienceDirect и Google Scholar. В анализ включены исследования, оценивающие стоимость, клиническую эффективность, показатели «затраты – эффективность» и «затраты – полезность» комбинаций ТТ и ЛТ.</p></sec><sec><title>Результаты</title><p>Результаты. ФК ТТ показала более высокую экономическую эффективность по сравнению с ЛТ в странах Европы и на Филиппинах, обеспечивая более низкие долгосрочные затраты и замедляя прогрессирование потери зрения. В Китае, напротив, применение ЛТ оказалось более экономически оправданным за счет более низких ежедневных расходов. Оба варианта ФК улучшали приверженность пациентов к лечению за счет удобства применения.</p></sec><sec><title>Заключение</title><p>Заключение. ФК ТТ может быть предпочтительным вариантом терапии ПОУГ с точки зрения фармакоэкономики и клинической эффективности в ряде регионов. Однако выбор конкретной схемы лечения должен учитывать региональные особенности, стоимость препаратов и доступность для пациентов.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>глаукома</kwd><kwd>травопрост</kwd><kwd>латанопрост</kwd><kwd>тимолол</kwd><kwd>фиксированные комбинации</kwd><kwd>экономическая эффективность</kwd><kwd>фармакоэкономика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glaucoma</kwd><kwd>travoprost</kwd><kwd>latanoprost</kwd><kwd>timolol</kwd><kwd>fixed-dose combinations</kwd><kwd>cost-effectiveness</kwd><kwd>pharmacoeconomics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Neelakantan A., Vaishnav H.D, Iyer S.A, Sherwood M.B.
