The development of new fix drug combination amlodipine and valsartan will provide in the near future a significant reduction in the cost of treatment. The aim of this work was investigation of bioequivalence for a generic drug Amlodipine+Valsartan, film-coated tablets, 10 mg+160 mg (Polpharma SA, Poland) and Exforge®, film-coated tablets, 10 mg+160 mg (Novartis Pharma AG, Switzerland). Materials and methods: 58 healthy volunteers were enrolled in open label, randomized, two sequence, two treatment cross-over study. Drugs were administered in two periods with a 21-day washout period in-between. Blood samples were collected over a 72-hour period. Amlodipine and Valsartan were measured in plasma using an automated LC-MS/MS assay. Pharmacokinetic parameters were calculated by non-compartmental analyses approach to evaluate AUC0-t, AUC0-∞ and Cmax. ANOVA was performed on the ln-transformed data and the 90% Confidence Interval (CI) was determined. Bioequivalence will be concluded if the 90% CI falls within 80-125% for AUC0-t and Cmax. Results: 53 volunteers completed the study and were considered for the pharmacokinetic and statistical analyses. Descriptive safety data analyses were performed on all 58 subjects. 90%-CI for corrected GMEAN of test and reference ratio was 94.76-105.24% for AUC0-t and 92.78-108.79% for Cmax in the case of amlodipine; 94.93-119.61% for AUC0-t and 90.41-116.03% for Cmax in the case of valsartan. So all pharmacokinetic parameters met the acceptance criteria as the 90% CI were within 80.00-125.00%. Conclusion: This study showed that Amlodipine+Valsartan, film-coated tablets, 10 mg+160 mg (Polpharma SA, Poland) is bioequivalent to reference product Exforge®, film-coated tablets, 10 mg+160 mg (Novartis Pharma AG, Switzerland).</p></abstract><trans-abstract xml:lang="ru"><p>Введение. Препарат Амлодипин+Валсартан является эффективным и безопасным комплексным средством для лечения артериальной гипертензии пациентам, которым показана комбинированная терапия. Появление новых дженериков комбинации амлодипин+валсартан обеспечит в ближайшем будущем существенное снижение стоимости лечения. Целью настоящей работы являлось исследование биоэквивалентности воспроизведённого лекарственного препарата Амлодипин+Валсартан («Польфарма» АО, Польша) в сравнении с препаратом Эксфорж® (Новартис Фарма АГ, Швейцария). Материал и методы. В открытое, одноцентровое, сравнительное, рандомизированное, двухэтапное, перекрестное клиническое исследование были включены 58 здоровых добровольцев. Сравниваемые препараты назначали однократно с интервалом 21 день. Пробы крови для анализа брали в течение 72 часов. Фармакокинетические параметры рассчитывали на основании концентраций амлодипина и валсартана в плазме, определенных валидированным методом с помощью высокоэффективной жидкостной хроматографии/тандемной масс-спектрометрии. Определение фармакокинетических параметров AUC0-t и Cmax выполняли внемодельным методом. Для ln-преобразованных данных был выполнен дисперсионный анализа ANOVA и определены 90% доверительные интервалы (ДИ). Заключение о биоэквивалентности сравниваемых препаратов могло быть сделано, если 90% ДИ находились в интервале 80-125% для AUC0-t и Cmax. Результаты. 53 добровольца завершили исследование и были включены в фармакокинетический и статистический анализ. В анализ безопасности были включены 58 добровольцев. 90% доверительные интервалы для отношения скорректированных геометрических средних исследуемого препарата и препарата сравнения составили: по амлодипину 94,76-105,24% для AUC0-t и 92,78-108,79% для Cmax; по валсартану 94,93-119,61% для AUC0-t и 90,41-116,03% для Cmax, а следовательно, находились в пределах стандартного диапазона приемлемости 80-125%. Оба препарата имели хорошую переносимость. Обсуждение и заключение. Препараты Амлодипин+Валсартан («Польфарма» АО, Польша) и Эксфорж® (Новартис Фарма АГ, Швейцария) биоэквивалентны.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Amlodipine</kwd><kwd>Valsartan</kwd><kwd>Exforge®</kwd><kwd>pharmacokinetics</kwd><kwd>bioequivalence</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Амлодипин</kwd><kwd>Валсартан</kwd><kwd>Эксфорж®</kwd><kwd>фармакокинетика</kwd><kwd>биоэквивалентность</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Шуникова М.И., Хохлов А.Л., Соснин А.Ю.
