To compare the kinetics of dissolution (in vitro) and some pharmacodynamic and pharmacokinetic parameters of branded generic preparations of acetylsalicylic acid (ASA) in buffered form in cardioprotective doses [ASA 75 mg+Mg(OH)2 15.2 mg], which differ in the composition of excipients, with a reference drug.</p></sec><sec><title>Material and methods</title><p>Material and methods. Patients with cardiovascular diseases who had indications for ASA monotherapy (n=75) were included in a one-center open postregistration comparative non-randomized study. Patients were divided into 3 groups for treatment with one of the three studied drugs: Cardiomagnyl® (comparison drug; group 1; n=25), Trombital® (group 2; n=25) and Fazostabil® (group 3; n=25). A study of the kinetics of dissolution of the studied drugs in vitro under conditions of pH 1.2 has been performed. Also, platelet aggregation in response to arachidonic acid, the concentration of salicylic acid and the level of serum thromboxane B2 were studied in the compared groups.</p></sec><sec><title>Results</title><p>Results. The average release profile of ASA by the 30th minute from Cardiomagnyl® was higher than for Trombital® and Fazostabil® (95.7%, 84.8%, 76.5% respectively). The similarity factor (f2) of ASA release for Trombital® was 39.3, and for Fazostabil® - 34.2. An index of f2&lt;50 indicates a nonequivalent release of ASA compared with the reference drug. The serum level of salicylic acid 2 hours after taking the first dose of the drug in patients of group 1 was 2657.3±648.4 ng/ml, in group 2 - 2637.0±740.0 ng/ml (p=0.03) and in group 3 it was to 2632.1±666.0 ng/ml (p=0.002). The platelet aggregation after 3 days decreased and in groups 1, 2 and 3 were respectively 7.6%, 32.2% (p=0.000) and 16.3% (p=0.009). Differences in the disaggregation effect between the groups persisted by the 7th day of the study (7.9%, 9.1% and 20.5% respectively; p=0.04 for the latter). The thromboxane B2 level by the 3rd day of administration decreased compared to the initial level in group 1 to 15.5%, in group 2 to 21.1% and in group 3 to 20.0% (p=0.05 for both). The trend persisted by the 7th day.</p></sec><sec><title>Conclusion</title><p>Conclusion. The pharmacodynamic and pharmacokinetic parameters of the studied drugs differed statistically significantly with the advantage for the comparison drug despite the same active substance.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Сравнить кинетику растворения in vitro, некоторые фармакодинамические и фармакокинетические показатели буферных дженерических препаратов ацетилсалициловой кислоты (АСК) в кардиопротективных дозах [АСК 75 мг+Мд(ОН)2 15,2 мг], отличающихся разным составом вспомогательных веществ, с референсным лекарственным средством.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В одноцентровое открытое пострегистрационное сравнительное нерандомизированное исследование последовательно были включены 75 пациентов с сердечно-сосудистыми заболеваниями, имевшие показания к монотерапии АСК. Больные были разделены на 3 группы по 25 человек для получения одного из трех изучаемых препаратов АСК 75 мг+Mg(OH)2 1 5,2 мг Кардиомагнил® (препарат сравнения; группа 1), Тромбитал® (группа 2) и Фазостабил®(группа 3). Проведено исследование кинетики растворения изучаемых препаратов in vitro в условиях pH 1,2. Также в сравниваемых группах изучена агрегация тромбоцитов в ответ на арахидоновую кислоту, концентрация салициловой кислоты и уровень тромбоксана В2 в сыворотке крови.</p></sec><sec><title>Результаты</title><p>Результаты. Кинетика растворения изучаемых препаратов показала, что усредненный профиль высвобождения АСК к 30-й минуте из Кардио-магнил®оказался выше, чем соответствующие значения для Тромбитал®и Фазостабил® (95,7%, 84,8%, 76,5% соответственно). Фактор подобия (f2) высвобождения АСК из Тромбитал® составил 39,3 и для Фазостабил® - 34,2. Показатель f2&lt;50 свидетельствует о неэквивалентном высвобождении АСК при сопоставлении с препаратом сравнения. Через 2 ч после приема первой дозы препарата уровень салициловой кислоты в крови больных группы 1 составил 2657,3±648,4 нг/мл, в группе 2 - 2637,0±740,0 нг/мл (p=0,03), а в группе 3 соответствовал 2632,1±666,0 нг/мл (p=0,002). Через 3 суток агрегация тромбоцитов больных снижалась, и в группах 1, 2 и 3 соответствовала 7,6%, 32,2% (p=0,000) и 16,3% (p=0,009). К 7-м суткам исследования различия в отношении дезагрегационного эффекта между группами сохранялись (7,9%, 9,1% и 20,5% соответственно; p=0,04 для последнего). Уровень тромбоксана В2 к 3-м суткам приема снижался по сравнению с показателями до приема препаратов в группе 1 до 15,5%, группе 2 до 21,1%, а в группе 3 до 20,0% (p=0,05 для обоих). К 7 суткам тенденция сохранялась.</p></sec><sec><title>Заключение</title><p>Заключение. Несмотря на одинаковую действующую субстанцию, кинетика растворения, фармакодинамические и фармакокинетические показатели изучаемых препаратов статистически значимо различались в пользу препарата сравнения.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>антитромбоцитарная терапия</kwd><kwd>ацетилсалициловая кислота</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>вторичная профилактика</kwd><kwd>лабораторная эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antiplatelet therapy</kwd><kwd>acetylsalicylic acid</kwd><kwd>coronary heart disease</kwd><kwd>secondary prevention</kwd><kwd>laboratory efficacy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Публикация статьи поддержана компанией Штада, что никоим образом не повлияло на собственное мнение авторов.</funding-statement><funding-statement xml:lang="en">The publication of the article is supported by Stada, but it did not affect own opinion of the authors.</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">Jain K.K.
