Также деферазирокс входит в перечень жизненно необходимых и важнейших лекарственных препаратов, что свидетельствует о значимости данного лекарственного средства для российского здравоохранения. В указанном перечне присутствуют препараты только зарубежного производителя, поэтому в рамках тенденции к импортозамещению разработка препаратов деферазирокса отечественного производства является необходимым и перспективным направлением. В связи с чем возникает необходимость разработки методики, позволяющей с минимальными временными и ресурсными затратами количественно определить деферазирокс в плазме крови человека в рамках фармакокинетического исследования.</p></sec><sec><title>Цель</title><p>Цель. Целью исследования является разработка и валидация методики определения деферазирокса в плазме крови человека методом высокоэффективной жидкостной хроматографии с ультрафиолетовым детектированием (ВЭЖХ-УФ) для дальнейшего исследования фармакокинетики и биоэквивалентности лекарственных препаратов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Определение деферазирокса в плазме крови человека проводили методом ВЭЖХ-УФ. В качестве пробоподготовки был использован способ осаждения белков ацетонитрилом. Раствор эрлотиниба использовался в качестве внутреннего стандарта. Подвижная фаза: 0,3%-й раствор ортофосфорной кислоты в воде, доведенный до pH 3,0 (элюент А) и 0,1%-й раствор муравьиной кислоты в ацетонитриле (элюент В). Колонка: Symmetry®, 75 × 4,6 мм (Waters, США). Аналитический диапазон методики для деферазирокса: 0,25–70,00 мкг/мл в плазме крови. Детектирование проводилось с помощью УФ-детектора при длине волны поглощения 299 ± 2 нм.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Валидация разработанной методики проводилась по следующим валидационным параметрам: селективность, калибровочная кривая, точность, прецизионность, степень извлечения, нижний предел количественного определения, перенос пробы, стабильность (стабильность исходных и рабочих стандартных растворов аналита и внутреннего стандарта; краткосрочная стабильность; стабильность при трехкратной заморозке-разморозке аналита; долгосрочная стабильность аналита в матрице).</p></sec><sec><title>Заключение</title><p>Заключение. Была разработана и валидирована методика определения лекарственного средства деферазирокс в плазме крови человека методом ВЭЖХ-УФ. Аналитический диапазон методики был подтвержден и составил 0,25–70,00 мкг/мл для деферазирокса в плазме крови. Данная методика была использована в рамках проведения исследования фармакокинетики и биоэквивалентности препаратов деферазирокса.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Deferasirox is one of the most well-known complexing drugs chelators and is successfully used in chelating therapy for the treatment of excess iron in the human body. Deferasirox is also included in the list of vital and essential medicines, which indicates the importance of this drug for Russian healthcare. In this document, there are drugs only from a foreign manufacturer, therefore, within the framework of the trend towards import substitution, the development of deferasirox preparations of domestic production is a necessary and promising direction. In this connection, there is a need to develop a method that allows quantifying deferasirox in human blood plasma with minimal time and resource costs as part of a pharmacokinetic study.</p></sec><sec><title>Aim</title><p>Aim. The aim of this study is to develop a method for quantitative determination of deferasirox in human blood plasma by high performance liquid chromatography coupled with ultraviolet detection (HPLC-UV) for further bioequivalence studies.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Determination of the deferasirox in human blood plasma was carried out by HPLC-UV. The method of proteins precipitation by acetonitrile was used as a sample preparation. Erlotinib solution was used as an internal standard. Mobile phase: 0.3 % solution of orthophosphoric acid in water, brought to pH 3.0 (eluent A) and 0.1 % solution of formic acid in acetonitrile (eluent B). Column was Symmetry®, 75 × 4,6 mm (Waters, США). Analytical range of the technique for deferasirox was 0.25–70.00 µg/ml in human blood plasma. Detection was carried out using a UV detector at an absorption wavelength of 299 ± 2 nm.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. This method was validated by selectivity, calibration curve, accuracy, precision, spike recovery, the lower limit of quantification, carry-over effect and stability.</p></sec><sec><title>Conclusion</title><p>Conclusion. A method of quantitative determination of deferasirox in human blood plasma was developed and validated by HPLC-UV. The analytical range was 0.25–70.00 µg/ml in human blood plasma. This method was used as part of a study of the pharmacokinetics and bioequivalence of deferasirox drugs.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>деферазирокс</kwd><kwd>плазма</kwd><kwd>железо</kwd><kwd>ВЭЖХ-УФ</kwd><kwd>валидация</kwd><kwd>определение</kwd><kwd>фармакокинетика</kwd><kwd>биоэквивалентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>deferasirox</kwd><kwd>human blood plasma</kwd><kwd>iron</kwd><kwd>HPLC-UV</kwd><kwd>validation</kwd><kwd>pharmacokinetics</kwd><kwd>bioequivalence</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">Díaz-García J.
