Лтд., Китай - серия RAB 20131102 (образец 1) и Нош Лабз Пвт. Лтд., Индия - серии RS 0280311 (образец 2) и RS 0120914 (образец 3). Микрофотографии получали на электронном микроскопе ТМ-1000, Hitachi. Порошковые дифрактограммы получали на автоматическом рентгеновском дифрактометре Bruker D8 Advance. Для идентификации кристаллических фаз использованы База данных порошковой дифрактометрии PDF-2 и Кембриджская база кристаллоструктурных данных. Сыпучесть фармацевтических субстанций определяли согласно ОФС 1.4.2.0016.15, фракционный состав - ситовым анализом; для оценки сжимаемости рассчитывали индексы Карра и Хауснера. </p></sec><sec><title>Результаты</title><p>Результаты. Образцы рабепразола натрия 1 и 2 имеют аморфную природу и характеризуются наличием двух аморфных гало в области углов 2θ 4-7° и 18-24°. Образец 3, вероятно, представляет собой смешанный вариант, в котором представлены аморфная и кристаллическая компонента. Исследованные образцы отличаются по насыпной плотности и фракционному составу. Образцы 2 и 3 более однородны по сравнению с образцом 1, их насыпная плотность является приемлемой для технологического процесса. </p></sec><sec><title>Заключение</title><p>Заключение. Фармацевтическая субстанция рабепразола натрия производителя Нош Лабз Пвт. Лтд. (Индия) имеет более однородный фракционный состав и приемлемую насыпную плотность. Однако использованные данным производителем технологические процессы не исключают образования в отдельных случаях кристаллической компоненты в фармацевтической субстанции, что может приводить к значительному изменению физико-химических и механических характеристик фармацевтической субстанции в различных партиях.</p></sec></abstract><trans-abstract xml:lang="en"><p>The purpose of the study is the choice of the pharmaceutical substance rabeprazole sodium with the optimal structure and technological characteristics for the development of Rabeprazole tablets. </p><sec><title>Materials and methods</title><p>Materials and methods. The study was conducted on samples of pharmaceutical substances rabeprazole sodium of two manufacturers Changzhou Koni Pharmaceutical Co. Ltd., China - RAB 20131102 Series (Sample 1) and Nosh Labs Pvt. Ltd., India - of RS 0280311 (sample 2) and RS 0120914 (sample 3). Microphotographs were obtained on a TM-1000 electron microscope, Hitachi. Powder X-ray diffraction patterns were obtained on a Bruker D8 Advance automatic X-ray diffractometer. To identify the crystalline phases, the PDF-2 Powder Diffractometry Database and the Cambridge Crystal Structural Database were used. The flowability of pharmaceutical substances was determined according to OFS 1.4.2.0016.15, the fractional composition was determined by sieve analysis; to evaluate compressibility, the Carr and Hausner indices were calculated. </p></sec><sec><title>Results</title><p>Results. Samples of rabeprazole sodium 1 and 2 are amorphous in nature and are characterized by the presence of two amorphous halo in the range of angles 2θ of 4-7 ° and 18-24 °. Sample 3 is probably a mixed version, in which an amorphous and crystalline component is presented. The studied samples differ in bulk density and fractional composition. Samples 2 and 3 are more uniform compared to sample 1, their bulk density is acceptable for the process. </p></sec><sec><title>Conclusion</title><p>Conclusion. Pharmaceutical substance rabeprazole sodium of manufacturer Nosh Labs Pvt. Ltd. (India) has a more uniform fractional composition and acceptable bulk density. However, the processes used by this manufacturer do not exclude the formation in some cases of a crystalline component in a pharmaceutical substance, which can lead to a significant change in the physicochemical and mechanical characteristics of the pharmaceutical substance in different batches.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рабепразол</kwd><kwd>кристаллы</kwd><kwd>сыпучесть</kwd><kwd>гранулометрический состав</kwd><kwd>микрофотографии</kwd><kwd>дифрактограммы.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rabeprazole</kwd><kwd>crystals</kwd><kwd>flowability</kwd><kwd>particle size distribution</kwd><kwd>microphotographs</kwd><kwd>diffraction patterns.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Электронно-микроскопические и рентгеноструктурные исследования выполнялись Губайдуллиным А.Т. в рамках государственного задания ФИЦ КазНЦ РАН (Рег.
