Апиксабан – антикоагулянт, применяющийся при ряде тромбоэмболических заболеваний и обладающий улучшенным соотношением пользы от приема препарата и рисков развития кровотечения согласно многочисленным клиническим исследованиям. В связи с назначением апиксабана в качестве антитромботической терапии пациентам с COVID-19 наблюдается рост его применения. Таким образом, из-за большого распространения апиксабана и необходимости проведения фармакокинетических исследований и исследований биоэквивалентности препаратов апиксабана важно разработать и валидировать простую и чувствительную методику количественного определения апиксабана в плазме крови.</p></sec><sec><title>Цель</title><p>Цель. Целью исследования является разработка и валидация методики определения апиксабана в плазме крови человека с помощью метода высокоэффективной жидкостной хроматографии с тандемным масс-селективным детектированием (ВЭЖХ-МС/МС) для последующего проведения фармакокинетического исследования.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Определение апиксабана в плазме крови человека проводили с помощью ВЭЖХ-МС/МС, используя ривароксабан как внутренний стандарт. Пробоподготовка проводилась путем осаждения белков плазмы крови ацетонитрилом. Подвижная фаза: 0,1%-й раствор муравьиной кислоты в воде (элюент А); 0,1%-й раствор муравьиной кислоты в ацетонитриле (элюент В). Время анализа: 3,00 мин. Колонка: Shim-pack Velox Biphenyl; 2,7 мкм; 50 × 2,1 мм. Источник ионизации: электроспрей с положительным режимом ионизации. MRM-переходы: 460,15 → 443,10 m/z (апиксабан); 436,05 → 144,95 m/z (ривароксабан).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Валидация проводилась согласно действующим требованиям ЕАЭС по следующим валидационным параметрам: селективность, калибровочная кривая, точность и прецизионность, нижний предел количественного определения, пригодность стандартных образцов, эффект матрицы, степень извлечения, стабильность, перенос пробы, отсутствие влияния разбавления образцов. Результаты оценки всех параметров соответствовали установленным критериям приемлемости.</p></sec><sec><title>Заключение</title><p>Заключение. Подтвержденный аналитический диапазон разработанной и валидированной методики составил 1,00–300,00 нг/мл в плазме крови. Методика определения апиксабана в плазме крови является простой и чувствительной. Данная методика была апробирована во время аналитической части исследования биоэквивалентности и может применяться для других фармакокинетических исследований препаратов апиксабана.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Apixaban is an anticoagulant used in a number of thromboembolic diseases with an improved benefit-to-risk ratio, according to multiple clinical studies. Due to the prescription of apixaban as antithrombotic therapy in patients with COVID-19, an increase in its use has been observed. Thus, due to the widespread use of apixaban and the need to conduct pharmacokinetic and bioequivalence studies of the drug, it is important to develop and validate a simple and sensitive method for the quantitative determination of apixaban in human blood plasma.</p></sec><sec><title>Aim</title><p>Aim. The aim of the study is to develop and validate a method for the determination of apixaban in human blood plasma using high-performance liquid chromatography with tandem mass selective detection (HPLC-MS/MS) for the subsequent bioanalytical study.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The determination of apixaban in human plasma was carried out by HPLC-MS/MS with rivaroxaban as an internal standard. The method of protein precipitation with acetonitrile was used as sample preparation. Mobile phase: 0.1 % solution of formic acid in water (eluent A); 0.1 % solution of formic acid in acetonitrile (eluent B). The total run time was 3.00 min. Column: Shim-pack Velox Biphenyl; 2.7 µm; 50 × 2.1 mm. Ionization source: electrospray with positive ionization mode. MRM transitions: 460.15 → 443.10 m/z (apixaban); 436.05 → 144.95 m/z (rivaroxaban).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The developed method was validated in accordance with the EAEU requirements for the following parameters: selectivity, calibration curve, accuracy and precision, lower limit of quantitation, suitability of standard samples, matrix effect, recovery, stability, carry-over, dilution effects. The parameters met the acceptance criteria.</p></sec><sec><title>Conclusion</title><p>Conclusion. The confirmed analytical range of the developed and validated method was 1.00–300.00 ng/mL in blood plasma. The method for determining apixaban in blood plasma is simple and sensitive. This method was tested during the analytical part of the bioanalytical study and can be used to conduct other pharmacokinetic studies of apixaban drugs.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>антикоагулянты</kwd><kwd>НОАК</kwd><kwd>апиксабан</kwd><kwd>ВЭЖХ-МС/МС</kwd><kwd>валидация</kwd><kwd>COVID-19</kwd><kwd>фармакокинетика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anticoagulants</kwd><kwd>DOAC</kwd><kwd>apixaban</kwd><kwd>HPLC-MS/MS</kwd><kwd>validation</kwd><kwd>COVID-19</kwd><kwd>pharmacokinetics</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">Воробьева Н.
