Амиодарон широко используется в качестве антиаритмического препарата, однако его эффективность не всегда предсказуема, а побочные эффекты не полностью контролируемы. Для определения эффективной концентрации амиодарона в крови необходима разработка методики количественного анализа препарата в присутствии биологической матрицы.</p></sec><sec><title>Цель</title><p>Цель: разработать методику количественного определения амиодарона (АМИ) и дезэтиламиодарона (ДЭА) в плазме крови человека методом высокоэффективной жидкостной хроматографии (ВЭЖХ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Метод разработан с использованием хромотографа Agilent 1260 Infinity (Agilent, США) с применением диодно-матричного детектора на экспериментальном образце колонки Tsunami C18 Pharm (250 × 4,6 mm, 5 μm) в условиях градиентного элюирования. Для защиты колонки от механических воздействий применялась предколонка Agilent Zorbax SB C8 (9,4 × 15 mm, 7 μm). Валидация проведена в соответствии с ОФС.1.1.0012.15 «Валидация аналитических методов» для следующих параметров: селективность, матричный эффект, линейность, точность, прецизионность, стабильность и предел количественного определения и обнаружения.</p></sec><sec><title>Результаты</title><p>Результаты. Пробоподготовка по методу QuEChERS была модифицирована для достижения оптимальных условий для извлечения АМИ и ДЭА из биологической матрицы. В качестве подвижной фазы А использовался буферный фосфат (pH 3, 7,5 mM), подвижной фазы B – 100% ацетонитрил. Режим элюирования – градиентный. До 7-й мин содержание фазы B составляло 55%, затем с 7-й мин до 7 мин 15 с наблюдалось увеличение содержания фазы B до 85% с целью элюирования более гидрофобных компонентов. С 7 мин 15 с до 15-й мин содержание фазы B не изменялось, а затем возвращалось к исходным 50% на 15 мин 15 с. Суммарное время анализа составило 18 мин; температура термостата – 30 °C; скорость потока – 1,2 мл/ мин; объем инжекции – 80 мкл; длина волны детектирования – 241 нм. Значение мешающего фактора для АМИ составило 2,25, для ДЭА – 1,44.</p></sec><sec><title>Выводы</title><p>Выводы.

Amiodarone is widely used as an antiarrhythmic drug, but its effectiveness is not entirely predictable, and its side effects are not completely controllable. To determine the effective concentration of amiodarone in the blood, a method for quantitative analysis of the drug in the presence of a biological matrix is needed.</p></sec><sec><title>Objective</title><p>Objective. To develop a procedure for quantitative determination of amiodarone (AMI) and desethylamiodarone (DEA) in blood plasma by high-performance liquid chromatography (HPLC).</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. The procedure was developed using an Agilent 1260 Infinity chromatograph with diode array detector (Agilent, USA) on a Tsunami C18 Pharm column (250×4.6 mm, 5 μm) with proprietary stationary phase. Agilent Zorbax SB C8 precolumn (9.4×15 mm, 7 μm) was used to protect the column from mechanical contaminants. Validation was performed according to OFS.1.1.0012.15 “Validation of Analytical Methods” for the following parameters: selectivity, matrix effect, linearity, accuracy, precision, stability and limits of detection and quantification.</p></sec><sec><title>Results</title><p>Results. The QuEChERS sample preparation was modified to achieve optimal conditions for the extraction of AMI and DEA from the biological matrix. Mobile phase A was phosphate buffer (pH 3, 7.5 mM), mobile phase B was 100% acetonitrile. The separation was performed in gradient mode. Up to 7.00 minutes – the B phase content was 55%, from 7.00 to 7.15 minutes – an increase in B phase content to 85% in order to elute the more hydrophobic components, from 7.15 to 15.00 minutes – the B phase content did not change, followed by a return to the original 50% at 15.15 min. The total analysis time was 18 minutes. Column thermostat temperature was set to 30 °C, flow rate – 1.2 mL/min; injection volume – 80 µL; selective wavelength was 241 nm. The value of retention factor for AMI was 2.25; for DEA – 1.44.</p></sec><sec><title>Conclusion</title><p>Conclusion. The authors have developed and validated the new HPLC procedure for quantitative identification of AMI and DEA in human blood plasma.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>высокоэффективная жидкостная хроматография</kwd><kwd>амиодарон</kwd><kwd>дезэтиламиодарон</kwd><kwd>плазма человек</kwd><kwd>разработка методики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-performance liquid chromatography</kwd><kwd>amiodarone</kwd><kwd>desethylamiodarone</kwd><kwd>human plasma</kwd><kwd>development of methodology</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование было выполнено при поддержке НИИ кардиологии Томского НИМЦ (Томск, Россия)</funding-statement><funding-statement xml:lang="en">the study was performed with the support of the Cardiology Research Institute, Tomsk National Research Medical Center, Russian Academy of Sciences, Tomsk, Russia.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Connolly S.J.
