Наибольшей эффективностью и безопасностью в лечении артериальной гипертензии обладают комбинированные лекарственные препараты. Комбинация кандесартана и гидрохлоротиазида (антагонист рецепторов АТ1 и тиазидный диуретик соответственно) обеспечивает высокую эффективность антигипертензивной комбинированной терапии и находит широкое применение в медицинской практике. Разработка методики совместного определения кандесартана и гидрохлоротиазида в плазме крови человека является необходимой процедурой для выполнения аналитической части фармакокинетических исследований и исследований биоэквивалентности многокомпонентных лекарственных средств.</p></sec><sec><title>Цель</title><p>Цель. Целью исследования является разработка и валидация методики определения кандесартана и гидрохлоротиазида в плазме крови человека методом высокоэффективной жидкостной хроматографии с тандемным масс-селективным детектированием (ВЭЖХ-МС/МС) для дальнейшего исследования биоэквивалентности.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Определение кандесартана и гидрохлоротиазида в плазме крови человека проводили методом ВЭЖХ-МС/МС. В качестве пробоподготовки был использован способ осаждения белков ацетонитрилом. Внутренний стандарт: смешанный раствор валсартана и индапамида. Подвижная фаза: 0,1 % раствор муравьиной кислоты в воде (элюент А), 0,1 % муравьиной кислоты в ацетонитриле (элюент В). Колонка: Phenomenex Luna Phenyl-Hexyl, 50 × 4,6 мм, 5 мкм. Аналитические диапазоны методики: 2,00–300,00 нг/мл для кандесартана, 2,00–200,00 нг/мл для гидрохлоротиазида в плазме крови. Источник ионизации: электроспрей. Условия детектирования: 441,10 → 192,00 m/z, 441,10 → 263,15 m/z (кандесартан), 295,85 →  269,00 m/z (гидрохлоротиазид), 436,00 → 207,05 m/z (валсартан), 363,85 → 132,10 m/z, 363,85 → 189,00 m/z (индапамид).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Разработанная методика была валидирована по следующим валидационным параметрам: селективность, эффект матрицы, калибровочная кривая, точность, прецизионность, степень извлечения, нижний предел количественного определения, перенос пробы, стабильность (стабильность исходных и рабочих стандартных растворов аналитов и внутренних стандартов; краткосрочная стабильность; стабильность при трехкратной заморозке-разморозке аналитов; долгосрочная стабильность аналитов в матрице). Разработанная и валидированная методика соответствует требованиям правил проведения исследований биоэквивалентности лекарственных препаратов в рамках Евразийского экономического союза.</p></sec><sec><title>Заключение</title><p>Заключение. Подтвержденный аналитический диапазон методики составил 2,00–300,00 нг/мл для кандесартана и 2,00–200,00 нг/мл для гидрохлоротиазида в плазме крови. Данная методика была использована в рамках проведения исследования биоэквивалентности комбинированных препаратов кандесартана и гидрохлоротиазида.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Combined drugs have the greatest efficacy and safety in arterial hypertension treatment. The combination of candesartan and hydrochlorothiazide (AT1-receptor antagonist and a thiazide diuretic, respectively) provides high efficiency of antihypertensive combination therapy, therefore it is widely used in medical practice. Developing a method for simultaneous determination of candesartan and hydrochlorithiazide in human blood plasma is necessary for performing the analytical part of pharmacokinetic studies and bioequivalence studies of multicomponent drugs.</p></sec><sec><title>Aim</title><p>Aim. The aim of this study is to develop a method for quantitative determination of candesartan and hydrochlorothiazide in human plasma by high-performance liquid chromatography – tandem mass spectrometry (HPLC-MS/MS) for further bioequivalence studies.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Determination of candesartan and hydrochlorothiazide in human plasma by HPLC-MS/MS. The samples were processed by acetonitrile protein precipitation. Internal standard: mixed solution of valsartan and indapamide. Mobile phase: 0.1 % formic acid solution in water (eluent A), 0.1 % formic acid in acetonitrile (eluent B). Column: Phenomenex Luna Phenyl-Hexyl, 50x4.6 mm, 5 μm. Analytical range: 2.00–300.00 ng/mL for candesartan, 2.00–200.00 ng/mL for hydrochlorothiazide in human plasma. Ionization source: electrospray ionization. Detection conditions: 441.10 → 192.00 m/z, 441.10 → 263.15 m/z (candesartan), 295.85 → 269.00 m/z (hydrochlorothiazide), 436.00 → 207.05 m/z (valsartan), 363.85 → 132.10, 363.85 → 189.00 m/z (indapamide).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. This method was validated by selectivity, matrix effect, calibration curve, accuracy, precision, spike recovery, the lower limit of quantification, carry-over effect and stability. The developed method meets the requirements for conducting bioequivalence studies of medicinal products within the framework of the Eurasian Economic Union.</p></sec><sec><title>Conclusion</title><p>Conclusion. The analytical range was 2.00–300.00 ng/mL for candesartan, 2.00–200.00 ng/mL for hydrochlorothiazide in human plasma. The method was applied in BE study of the combination of candesartan and hydrochlorothiazide.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кандесартан</kwd><kwd>гидрохлоротиазид</kwd><kwd>плазма</kwd><kwd>ВЭЖХ-МС/МС</kwd><kwd>валидация</kwd><kwd>определение</kwd><kwd>фармакокинетика</kwd><kwd>биоэквивалентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>candesartan</kwd><kwd>hydrochlorothiazide</kwd><kwd>plasma</kwd><kwd>blood</kwd><kwd>HPLC-MS/MS</kwd><kwd>validation</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">ВОЗ публикует статистику о ведущих причинах смертности и инвалидности во всем мире за период 2000–2019 гг.
