Изучение влияния вспомогательных веществ на свойства гелей с цетилпиридиния хлоридом и выбор гелеобразователей, перспективных для разработки состава геля стоматологического. При этом учитывали свойства действующего вещества, особенности конкретных гелеобразователей, а также их влияние на устойчивость, биофармацевтические и потребительские свойства гелей.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследовании рассматривали полимеры с различными механизмами гелеобразования. Изучали их совместимость с цетилпиридиния хлоридом, устойчивость гелей при хранении, кинетическую устойчивость и коллоидную стабильность, pH водных извлечений, намазываемость и текстурные свойства, проникающую способность методом диффузии в агар, осмотическую активность и реологические свойства гелей. Для комплексного анализа результатов исследований гелевых композиций использовали обобщённую функцию желательности.</p></sec><sec><title>Результаты</title><p>Результаты. Устойчивые однородные гели стоматологические с цетилпиридиния хлоридом могут быть получены при использовании в качестве основы 25 % полоксамера 407 и 5,0 % хитозана высокомолекулярного. Введение в гели хитозана высокомолекулярного полоксамера 188 позволяет получать стабильные системы c улучшенными текстурными характеристиками, а также значительно увеличивает их осмотическую активность. Добавление агара, а также хитозана низкомолекулярного значительно уменьшает, а полоксамера 188 и полиэтиленгликолей разных молекулярных масс – увеличивает осмотическую активность гелей 25 % полоксамера 407, которые характеризуются также и высокой проникающей способностью.</p></sec><sec><title>Заключение</title><p>Заключение. По итогам комплексной оценки биофармацевтических, физико-химических и потребительских свойств гелей установлено, что в качестве основы для геля стоматологического с цетилпиридиния хлоридом могут быть рекомендованы комбинации полоксамера 407 с поливинилпирролидоном, агаром и хитозаном низкомолекулярным.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to determine the excipients influence on the characteristics of gels with cetylpyridinium chloride and to select the dental gel formulation gelation agents promising for the development of dental gel compositions. Hereby, the properties of the active pharmaceutical ingredient, characteristics of the specific gelation agents, as well as their influence on stability, biopharmaceutical and application properties of gels, were taken into account. </p><sec><title>Materials and methods</title><p>Materials and methods. In this study, polymers with various gelation mechanisms were considered. Their compatibility with cetylpyridinium chloride as well as storing kinetic and colloid kinds of stability, pH of aqueous solutions, spreadability and textural properties, a penetration ability by the agar diffusion method, an osmotic activity and rheological properties of the gels, were examined. For a complex evaluation of gel compositions study results, a desirability function was used.</p></sec><sec><title>Results</title><p>Results. Stable homogenous dental gels with cetylpyridinium chloride can be obtained by using 25% poloxamer 407 and 5.0% high molecular weight chitosan as the basis.</p><p>The addition of poloxamer 188 to high molecular weight chitosan gels can produce stable systems with improved textural characteristics as well as increase their osmotic activity. Agar and low molecular weight chitosan addition significantly decrease, whereas poloxamer188 and various molecular weight polyethyleneglycol increase the osmotic activity of 25 % poloxamer 407 gels which are also characterized by a high penetration ability.</p></sec><sec><title>Conclusion</title><p>Conclusion. A complex evaluation of biopharmaceutical, physicochemical and application properties of the gels made it possible to establish that combinations of poloxamer 407 with polyvinylpyrrolidone, agar, and low molecular weight chitosan, can be recommended as a base for a dental gel with cetylpyridinium chloride.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цетилпиридиния хлорид</kwd><kwd>гель стоматологический</kwd><kwd>состав</kwd><kwd>вспомогательные вещества</kwd><kwd>биофармацевтические свойства</kwd><kwd>хитозан</kwd><kwd>полоксамер</kwd><kwd>функция желательности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cetylpyridinium chloride</kwd><kwd>dental gel</kwd><kwd>composition</kwd><kwd>excipients</kwd><kwd>biopharmaceutical properties</kwd><kwd>chitosan</kwd><kwd>poloxamer</kwd><kwd>desirability function</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование не имело финансовой поддержки от сторонних организаций.</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">Всемирная организация здравоохранения.
