Ивермектин известен как ветеринарное средство с широким спектром действия в отношении эндо- и экзопаразитов сельскохозяйственных животных, что делает его применение перспективным. Поэтому в настоящее время исследуется возможность создания пролонгированнных парентеральных лекарственных форм с использованием полимерных биоразлагаемых носителей. Для осуществления их контроля качества необходима методика количественного определения активного вещества. Большинство предложенных ранее методик отличаются трудоемкой пробоподготовкой, сложным составом подвижной фазы или длительным временем анализа, поэтому в ходе разработки инъекционного пролонгированного препарата ивермектина на основе микрочастиц поликапролактона была предложена новая методика количественного определения ивермектина, отличающаяся простотой и пригодная для применения на производстве.</p></sec><sec><title>Цель</title><p>Цель. Разработка методики количественного определения ивермектина в составе микрочастиц поликапролактона и проведение ее валидации.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В качестве объекта исследования использовали микрочастицы поликапролактона содержащие инкапсулированный ивермектин. Методика количественного определения ивермектина в исследуемом образце разрабатывалась на высокоэффективном жидкостном хроматографе Dionex UltiMate 3000 (Thermo Fisher Scientific, США), оснащенном диодно-матричным детектором.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. В настоящей работе изучены различные условия количественного определения ивермектина в составе микрочастиц поликапролактона.

В результате проведения разработки методики выбраны условия проведения анализа, которые позволяют оценивать количественное содержание ивермектина в образце. Проведена валидация методики по параметрам специфичность, аналитическая область, линейность, правильность, повторяемость и внутрилабораторная прецизионность.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Ivermectin is known as a veterinary agent with a wide spectrum of action against endo-and exoparasites of farm animals, which makes its use promising. Therefore, the possibility of creating prolonged parenteral dosage forms using polymer biodegradable carriers is currently being investigated. To carry out their quality control, a method of quantitative determination of the active substance is necessary. Most of the previously proposed methods are characterized by time-consuming sample preparation, complex composition of the mobile phase or a long analysis time, therefore, during the development of an injectable prolonged preparation of ivermectin based on polycaprolactone microparticles, a new method for the quantitative determination of ivermectin was proposed, which is simple and suitable for use in production.</p></sec><sec><title>Aim</title><p>Aim. Development of a method for the quantitative determination of ivermectin in the composition of polycaprolactone microparticles and its validation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Microparticles with ivermectin were used as the object of the study. The method of quantitative determination of ivermectin in the test sample was developed on a high-performance liquid chromatograph Dionex UltiMate 3000 (Thermo Fisher Scientific, USA), equipped with a diode-matrix detector.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. In this paper, various conditions for the quantitative determination of ivermectin in the composition of polymer microparticles are studied. Based on the obtained data and results, a method has been developed that has optimal sample preparation and analysis conditions.</p></sec><sec><title>Conclusion</title><p>Conclusion. As a result of the development, the conditions for the analysis were selected, which allow us to evaluate the quantitative content of ivermectin in the sample. The method was validated for the parameters specificity, analytical area, linearity, trueness, repeatability, intermediate precision.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ивермектин</kwd><kwd>полимерные микрочастицы</kwd><kwd>высокоэффективная жидкостная хроматография</kwd><kwd>валидация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ivermectin</kwd><kwd>polymer microparticles</kwd><kwd>high-performance liquid chromatography</kwd><kwd>validation</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">Meleny W.
