В последние десятилетия были предложены различные способы повышения растворимости субстанций: получение твердых дисперсий, микронизация, солюбилизация и другие, в том числе методы, основанные на переводе субстанций из кристаллического состояния в аморфное. К последним относятся: распылительная сушка, экструзия горячего расплава, абсорбция на мезопористых носителях, таких как магния алюмосиликат, кремния диоксид и прочие.</p></sec><sec><title>Цель</title><p>Цель. Изучение влияния технологических методов аморфизации путем абсорбции на мезопористых носителях практически нерастворимой ФС эфавиренза на растворение при физиологических значениях температуры и рН.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Эфавиренз форма І (EFA) (ООО «АМЕДАРТ», Россия, серия 010520). Эфавиренз стандартный образец (USP № R09740). Мезопористые носители (МН): кремния диоксид марок – Syloid® 244FP (244), Syloid® XDP 3150 (3150) (W. R. Grace  &amp; Co.-Conn, США); FujiSil™ (FSL) (Fuji Chemical Industries Co., Ltd., Япония); Aeroperl® 300 (APL) (Evonik, Германия); Parteck® SLC (SLC) (Merck Millipore, США); синтетический магния алюмосиликат – Neusilin® US2 (US2), Neusilin® UFL (UFL) (Fuji Chemical Industry Co., Ltd., Япония). Абсорбцию ФС на МН осуществляли методами испарения органического растворителя и методом экструзии горячего расплава.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Исходя из полученных данных можно сделать вывод, что растворение увеличивается в ряду МН SLC &gt; FSL &gt; UFL = US2 &gt; 244 = 3150, что согласуется с увеличением поверхности и уменьшением размеров пор МН. С этим так же согласуется кристаллическое состояние системы ФС эфавиренз-Aeroperl® за счет самого крупного размера пор. При сравнении методов получения рентгеноаморфных систем ФС эфавиренз-МН, очевидно, что метод удаления растворителя дает более высокие результаты по сравнению с технологией экструзии горячего расплава.</p></sec><sec><title>Заключение</title><p>Заключение. Для увеличения растворения практически нерастворимых фармацевтических субстанций рекомендуется использовать технологию удаления растворителя, а так же такие мезопористые носители, как кремния диоксид Parteck® SLC или синтетический магния алюмосиликат Neusilin® US2.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The low solubility of active pharmaceutical ingredients (APIs) in the physiological pH range of the intestinal tract can adversely affect their absorption and bioavailability. Various methods of increasing the solubility of APIs have been proposed in recent decades. Among them there are preparation of solid dispersions, micronization, solubilization and other methods, including ones based on the amorphization of the crystalline substances, such as, spray drying, hot melt extrusion, absorption on mesoporous carriers such as magnesium aluminosilicate, silica, etc.</p></sec><sec><title>Aim</title><p>Aim. Study the technological methods effect on dissolution at physiological temperature and pH range of practically insoluble API efavirenz amorphized by absorption on mesoporous carriers.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Efavirenz form І (EFA) (LLC "AMEDART", Russia, batch 010520). Efavirenz reference standard (USP № R09740). Mesoporous carriers (MC): Silica – Syloid® 244FP (244), Syloid® XDP 3150 (3150) (W.R. Grace&amp;Co.-Conn, USA); FujiSil™ (FSL) (Fuji Chemical Industries Co., Ltd., Japan); Aeroperl® 300 (APL) (Evonik, Germany); Parteck® SLC (SLC) (Merck Millipore, USA); Synthetic magnesium aluminometasilicate – Neusilin® US2 (US2), Neusilin® UFL (UFL) (Fuji Chemical Industry Co., Ltd., Japan). The API absorption on MC was performed via solvent wetting and hot melt extrusion methods.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The dissolution increases in the MC series as the following: SLC &gt; FSL &gt; UFL = US2 &gt; 244 = 3150. The data are consistent with an increase in the surface area and a decrease in the pore size of MC. The crystalline state of the system API efavirenz-Aeroperl® is caused by the largest pore size. It is obvious according to the data that the solvent wetting method gives better results in comparison with the hot melt extrusion as the method of obtaining X-ray amorphous systems API efavirenz-MC.</p></sec><sec><title>Conclusion</title><p>Conclusion. Solvent wetting technology is recommended for increasing the dissolution of practically insoluble APIs. The preferable mesoporous carriers are silica Parteck® SLC or synthetic magnesium aluminometasilicate Neusilin® US2.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эфавиренз</kwd><kwd>мезопористые носители</kwd><kwd>аморфизация</kwd><kwd>растворение</kwd><kwd>метод удаления растворителя</kwd><kwd>экструзия горячего расплава</kwd></kwd-group><kwd-group xml:lang="en"><kwd>efavirenz</kwd><kwd>mesoporous carriers</kwd><kwd>amorphization</kwd><kwd>dissolution</kwd><kwd>solvent wetting</kwd><kwd>hot melt extrusion</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">Davis M., Walker G.
