Omega-3 polyunsaturated fatty acids (ω3-PUFA) essential for female reproductive and somatic health exert a multi-faceted modulatory effect on metabolism of eicosanoids (including prostaglandins, lipoxins and leukotrienes) and docosanoids (neuroprotectins, resolvins, maresins).</p></sec><sec><title>Aim</title><p>Aim: to compare diverse ω3-PUFA samples assessing the degree of composition standardization for eicosapentaenoic (EPA) ω3-PUFA and docosahexaenoic (DHA) ω3-PUFA, as well as the degree of purification from fatty acid admixtures.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. The work presents chromatographic analysis results for 10 ω3-PUFA-based preparations.</p></sec><sec><title>Results</title><p>Results. The study allowed to reveal the compositional parameters for ω3-PUFA extracts, which can be used to distinguish between pharmaceutically standardized (Omacor, Femibion Natalcare-II, etc.) and less standardized ω3-PUFA preparations (Omeganol, Omegamama, etc.).</p></sec><sec><title>Conclusion</title><p>Conclusion. The more standardized preparation Femibion Natalcare-II is effective and safe for supporting reproductive function during pregnancy and for improving children’s neurological development. Omacor is a highly standardized preparation, however, not being officially approved for use in pregnant women.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Введение</title><p>Введение. Омега-3 полиненасыщенные жирные кислоты (ω3-ПНЖК), модулируя сложным образом обмен эйкозаноидов (в том числе простагландинов, липоксинов и лейкотриенов) и докозаноидов (нейропротектинов, резолвинов, маресинов), являются важным фактором репродуктивного и соматического здоровья женщин.</p></sec><sec><title>Цель</title><p>Цель: сравнить образцы ω3-ПНЖК по степени стандартизации состава по эйкозапентаеновой (ЭПК) ω3-ПНЖК и докозагексаеновой (ДГК) ω3-ПНЖК, оценить степень очистки от жирнокислотных примесей.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В работе представлены результаты хроматографического анализа 10 препаратов ω3-ПНЖК.</p></sec><sec><title>Результаты</title><p>Результаты. Исследование позволило выявить показатели состава экстрактов ω3-ПНЖК, посредством которых возможно отличать фармацевтически стандартизированные препараты ω3-ПНЖК (Омакор, Фемибион Наталкер-2 и др.) от менее стандартизированных препаратов (Омеганол, Омегамама и др.).</p></sec><sec><title>Заключение</title><p>Заключение. Более стандартизированный препарат Фемибион Наталкер-2 эффективен и безопасен для поддержки репродуктивной функции во время беременности и для улучшения неврологического развития детей. Омакор – высоко стандартизированный препарат, но не имеет официального разрешения к применению у беременных.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фармацевтическая стандартизация препаратов</kwd><kwd>омега-3 полиненасыщенные жирные кислоты</kwd><kwd>ω3-ПНЖК</kwd><kwd>нейрогенез</kwd><kwd>офтальмогенез</kwd><kwd>рост эмбриона и плода</kwd><kwd>топологический анализ данных</kwd><kwd>фармакоинформатика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pharmaceutical standardization of preparations</kwd><kwd>omega-3 polyunsaturated fatty acids</kwd><kwd>ω3-PUFA</kwd><kwd>neurogenesis</kwd><kwd>ophthalmogenesis</kwd><kwd>embryonic and fetal growth</kwd><kwd>topological data analysis</kwd><kwd>pharmacoinformatics</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья опубликована при поддержке ООО «Др.
