Они предназначены как для системного, так и для местного действия активных фармацевтических ингредиентов (АФИ), входящих в их состав. АФИ из диспергируемых форм попадают непосредственно в системный кровоток, минуя «эффект первого прохождения через печень».</p></sec><sec><title>Цель</title><p>Цель. Разработка диспергируемых в ротовой полости таблеток на основе полимер-лекарственного комплекса (ПЛК) Eudragit® EPO/ибупрофена и оценка высвобождения АФИ из полученной системы.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Получены образцы ПЛК при различном соотношении Eudragit® EPO (EPO) и ибупрофена (ИБ), а также при разном порядке смешивания. Турбидиметрические исследования по поиску стехиометрии образующегося ПЛК ЕРО/ИБ проводили спектрофотометрически (Lambda 25, PerkinElmer, США) при длине волны 600 нм. Термический анализ проводился методом модулированной дифференциальной сканирующей калориметрии (мДСК) на приборе Discovery™ DSC (TA Instruments, США). Образцы, завальцованные в алюминиевые тигли Tzero (TA Instruments, США), сканировали в диапазоне температур от 0 до 250 °С при скорости2 °С/мин. ИК-спектры регистрировали на ИК-Фурье-спектрометре Nicolet iS5 (Thermo Fisher Scientific, США) с ATR насадкой, в диапазоне от 500 до 4000 см-1. Сушка образцов комплексов и диспергируемых таблеток проводилась в лабораторной лиофильной сушилке FreeZone 1L (Labconco, США) в течение суток при температуре –49 °С и при давлении 0,350 мбар. Оценку высвобождения проводили на тестере растворения DT 828 (ERWEKA GmbH, Германия) в объеме 900 мл, при 37 ± 0,5 °C и скорости вращения лопастей 50 об/мин.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Исследования по образованию полимер-лекарственных комплексов Eudragit® EPO/ибупрофен (ЕРО/ИБ) проводили при различном мольном соотношении. На образцах ПЛК и индивидуальных компонентов наблюдаются полосы, характерные как для ЕРО – при 2770 и 2820 см-1, подтверждающие наличие неионизированных диметиламино-групп, так и при1725 см-1, соответствующую валентным колебаниям карбоксильных групп. Появление новой полосы при 1573 см-1 подтверждает образование ионной связи между карбоксилатными группами ИБ и ионизированными диметиламино-группами ЕРО. мДСК-термограммы образцов характеризуются единственной температурой стеклования (Тс) при 27,3 ± 0,3 °С (для соотношения 1 : 2) и 44,9 ± 0,4 °С (для соотношения 1 : 1), что подтверждает образование полимер-лекарственных комплексов. Получены ПЛК Eudragit® EPO/ибупрофен в мольном соотношении 1 : 2 и 1 : 1 и диспергируемые в полости рта таблетки на их основе методом лиофилизации. Полученные системы характеризуются немедленным высвобождением ИБ с максимальными показателями при 30 мин – для состава 1 : 1 и 60 мин для состава 1 : 2.</p></sec><sec><title>Заключение</title><p>Заключение. Полимер-лекарственный комплекс Eudragit® EPO/ибупрофен может быть использован для разработки диспергируемых в ротовой полости таблеток, обеспечивая немедленное высвобождение ИБ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Orodispersible dosage forms are a very promising direction in the development of dosage forms. Such dosage forms are designed for both systemic and local action of the active pharmaceutical ingredients that make up their composition. Active pharmaceutical ingredients from orodispersible forms enter directly into the systemic circulation, bypassing the "first pass effect".</p></sec><sec><title>Aim</title><p>Aim. Development of orodispersible tablets based on the Eudragit® EPO/ibuprofen polymer-drug complex and evaluation of ibuprofen release from the resulting system.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Samples of the polymer-drug complex (PDC) were obtained with different ratios of EPO and ibuprofen, as well as with different mixing orders. Turbidimetric studies to find the stoichiometry of the resulting EPO/IB PLC were performed spectrophotometrically (Lambda 25, PerkinElmer, U.S.A.) at a wavelength of 600 nm. Thermal analysis was performed by modulation differential scanning calorimetry (mDSC) on a Discovery™ DSC instrument (TA Instruments, U.S.A.). Samples sealed in Tzero aluminum pans (TA Instruments, U.S.A.) were scanned in the temperature range from 0 to 250 °С at a speed of 2 °С/min. IR spectra were recorded on a Nicolet iS5 FT-IR spectrometer (Thermo Fisher Scientific, U.S.A.) with an ATR nozzle, in the range from 500 to 4000 cm-1. Drying of samples of complexes and dispersible tablets was carried out in a FreeZone 1L laboratory freeze dryer (Labconco, U.S.A.) for a 24 hours at a temperature of –49 °C and at a pressure of 0.350 mbar. The drug release was evaluated on a dissolution tester DT 828 (ERWEKA GmbH, Germany) in a volume of 900 ml, at 37 ± 0.5 °C and a blade rotation speed of 50 rpm.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Studies on the formation of PDC Eudragit® EPO/ibuprofen (EPO/IB) were carried out at various molar ratios. On samples of PDC and individual components, bands are observed that are characteristic both for EPO – at 2770 and 2820 cm-1, confirming the presence of non-ionized dimethylamino groups, and at 1725 cm-1, corresponding to the stretching vibrations of carboxyl groups. A new band is appeared at 1573 cm-1, which confirm the formation of ionic bonds between carboxylate groups of IB and ionized dimethylamino groups of EPO. The mDSC thermograms of the samples are characterized by a single glass transition temperature (Tg) at 27,3 ± 0,3 °С (for molar ratio 1 : 2) and 44,9 ± 0,4 °С. (for molar ratio 1 : 1), which confirm the formation of polymer-drug complexes. Received PDC Eudragit® EPO/ibuprofen in a molar ratio of 1 : 2 and 1 : 1 and oral dispersible tablets based on them by lyophilization. The resulting systems are characterized by immediate release of IB with maximum rates at 30 min for a 1 : 1 composition and 60 min for a 1 : 2 composition.</p></sec><sec><title>Conclusion</title><p>Conclusion. Eudragit® EPO/ibuprofen polymer drug complex can be used to develop orodispersible tablets providing immediate release of IB.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диспергируемые в полости рта таблетки</kwd><kwd>Eudragit® EPO</kwd><kwd>ибупрофен</kwd></kwd-group><kwd-group xml:lang="en"><kwd>orodispersible tablets</kwd><kwd>Eudragit® EPO</kwd><kwd>ibuprofen</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Российского научного фонда (научный проект № 20-75-00051).</funding-statement><funding-statement xml:lang="en">The study was carried out with the financial support of the Russian Science Foundation (RSF) in the framework of research project № 20-75-00051 (to V.R.T., R.R.K., E.S.E.).</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">Comoglu T., Inal O., Yaacoub H.
