В рамках сравнительной оценки качества лекарственных препаратов, представленных на рынке РФ, проведено исследование теста сравнительной кинетики растворения (ТСКР) и показателя однородности дозирования долей таблеток для семи торговых наименований лекарственных препаратов с МНН «Каптоприл» различных производителей. ТСКР проводили в трех средах растворения (0,1 M раствор хлористоводородной кислоты, ацетатный буферный раствор рН 4,5 и фосфатный буферный раствор рН 6,8) на основании отбора проб по временным точкам 0, 5, 10, 15, 20, 30 мин и их анализа методом УФ-спектрофотометрии при длине волны 212 нм. Проведено сопоставление кинетики высвобождения действующего вещества на основании расчета фактора подобия f2 и значений относительных стандартных отклонений. Результаты однородности дозирования половин таблеток оценивали на основании расчета фактора АV, анализируя образцы при помощи метода ВЭЖХ-УФ.</p></sec><sec><title>Цель</title><p>Цель. Целью настоящего исследования являлась сравнительная оценка лекарственных препаратов с МНН «Каптоприл» различных производителей, представленных на рынке РФ, на основании исследований однородности дозирования и теста кинетики растворения как критериев оценки качества объектов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование ТСКР проводили с использованием тестера растворения DT 827/1000 (ERWEKA GmbH, Германия). Каждый лекарственный препарат анализировали в трех средах растворения по 12 повторах для каждой среды растворения. Отобранные пробы анализировали на УФ-спектрофотометре UV 1800 (Shimadzu, Япония) при длине волны 212 нм. При исследовании однородности дозирования половин таблеток проводили деление таблеток в соответствии с нанесенной риской, в случае если такая была нанесена, после чего проводили пробоподготовку в соответствии с валидированной методикой, полученные пробы анализировали методом ВЭЖХ-УФ на системе Agilent 1260 (Agilent Technologies, США).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. На основании результатов ТСКР и проведенных расчетов факторов подобия и значений относительного стандартного отклонения можно сделать вывод о неэквивалентности кинетики высвобождения для ЛП № 4, ЛП № 5, ЛП № 6 в сравнение с референтным препаратом. Проведённое исследование однородности дозирования действующего вещества не выявило отклонений в соответствии с требованиями ГФ РФ, ОФС.1.4.2.0008.18 «Однородность дозирования» и Фармакопеи ЕАЭС ОФС.2.1.9.14 «Однородность дозированных единиц».</p></sec><sec><title>Заключение</title><p>Заключение. Проведенные выборочные анализы лекарственных препаратов по показателям ТСКР и однородности дозирования на своем примере показывают возможность выявить потенциальные проблемы качества лекарственный препаратов, представленных на рынке РФ, а следовательно, развивать и поддерживать обеспечение качества лекарственных препаратов для национальной системы здравоохранения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. As part of a comparative assessment of drugs quality available on the Russian market a dissolution profile studies and uniformity of dosage units test was conducted for various manufacturers of "Captopril" drugs. Drug release studies in three dissolution media (0.1 M hydrochloric acid, acetate buffer pH 4.5, phosphate buffer pH 6.8) with sampling at 0, 5, 10, 15, 20, 30 min and analysis using UV/Vis spectrophotometer at 212 nm were conducted. Dissolution kinetics was compared based on calculation of the similarity factor f2 and the values of relative standard deviations. Uniformity of dosage units test of scored tablets were evaluated based on HPLC-UV analysis and AV factor calculation.</p></sec><sec><title>Aim</title><p>Aim. The purpose of this study was a comparative evaluation of "Captopril" drugs from various manufacturers on the Russian market based on dissolution profile studies and uniformity of dosage units test of scored tablets in order to assess the quality of the tablets.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. To prove the dissolution profile studies DT 827/1000 tester (ERWEKA GmbH, Germany) was applied. Each drug in three dissolution media in 12 replicates for each dissolution medium was analyzed. The selected samples were analyzed on a UV 1800 UV spectrophotometer (Shimadzu, Japan) at a of 212 nm. In uniformity of dosage units test of scored tablets each tablet was divided according to the applied mark. Sample preparation was carried out in accordance with a validated method and samples were analyzed by HPLC-UV using Agilent 1260 (Agilent Technologies, США).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Based on the results of dissolution profile studies and calculations of the similarity factors and values of the relative standard deviation it can be concluded that the dissolution kinetics for drug no. 4, drug no. 5, drug no. 6 are not equivalent in comparison with the reference drug. During the uniformity of dosage units test of scored tablets, no deviations were found in accordance with the requirements of the RF Pharmacopoeia OFS.1.4.2.0008.18 "Uniformity of dosing" and the EAEU Pharmacopoeia OFS.2.1.9.14 "Uniformity of Dosed Units".</p></sec><sec><title>Conclusion</title><p>Conclusion. The conducted dissolution profile studies and uniformity of dosage for scored tablets of Captopril drugs show the example of possibility to identify potential problems with drugs quality presented on the Russian market and as a result improve and maintain quality assurance of drugs for the national healthcare system.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>«Каптоприл»</kwd><kwd>ТСКР</kwd><kwd>однородность дозирования</kwd><kwd>таблетки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>"Captopril"</kwd><kwd>dissolution profile studies</kwd><kwd>uniformity of dosage</kwd><kwd>tablets</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">Tastemur Y., Gumus E., Ergul M., Ulu M., Akkaya R., Öztürk A., Taskiran A.
