Пантопразола натрия сесквигидрат является ингибитором протонной помпы. Данное вещество применяется в лечении язвенной болезни двенадцатиперстной кишки или желудка в фазе обострения, в том числе ассоциированной с приемом нестероидных противовоспалительных средств.</p></sec><sec><title>Текст</title><p>Текст. По своей структуре пантопразол представляет натриевую соль 5-(дифторметокси)-2-(3,4-диметокси-2-пиридинил)метил)сульфинил)-1-H-бензимидазола. Субстанция легко растворима в воде и этиловом спирте. Подлинность пантопразола подтверждают методом инфракрасной спектроскопии, а также положительной реакцией на ион натрия. Для количественного определения данного вещества используют химические и физико-химические методы. Так к первой группе относится титрование в неводной среде хлорной кислотой и перманганатометрия. Из физико-химических методов применяют спектрофотометрию и ВЭЖХ. Наиболее часто используется прямая спектрофотометрия, связанная с измерением оптической плотности при длине волны максимума поглощения пантопразола в различных растворителях. Кроме того, известны спектрофотометрические методики количественного определения, основанные на изучении поглощения окрашенных продуктов реакции пантопразода. Для анализа его препаратов используют производную спектрофотометрию. Контроль содержания примесей и пантопразола в субстанции и его лекарственных формах осуществляют, как правило, с помощью ВЭЖХ.</p></sec><sec><title>Заключение</title><p>Заключение. Анализ литературы показывает, что данное вещество является нестабильным. Поэтому эту его особенность необходимо учитывать при выборе вспомогательных веществ при разработке лекарственной формы. Предпочтительным методом анализа препаратов пантопразола является ВЭЖХ, так как можно определять вещество в присутствии других соединений, что позволит контролировать количественное содержание и стабильность пантопразола в препарате.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Pantoprazole sodium sesquihydrate is a proton pump inhibitor. This substance is used in the treatment of peptic ulcer of the duodenum or stomach in the acute phase, including those associated with the use of non-steroidal anti-inflammatory drugs.</p></sec><sec><title>Text</title><p>Text. Pantoprazole is sodium 5-(difluoromethoxy)-2-[(RS)-[(3,4-dimethoxypyridin-2-yl)methyl]sulfinyl]benzimidazol-1-ide sesquihydrate in its structure. The substance is readily soluble in water and ethyl alcohol. The identification of pantoprazole is confirmed by infrared absorption spectrophotometry, as well as by a positive reaction to sodium ion. For the assay of this substance chemical and physico-chemical methods are used. The first group of methods includes titration in a non-aqueous medium with perchloric acid and permanganatometry. Physico-chemical methods used for pantoprazole assay are spectrophotometry and HPLC. The most commonly used method is direct spectrophotometry associated with the measurement of optical density at a wavelength of the maximum absorption of pantoprazole in various solvents. In addition, spectrophotometric methods of assay are known, based on the study of the absorption of colored pantoprazode reaction products. The derivative spectrophotometry is used for the analysis of its preparations. The control of the content of impurities and pantoprazole in the substance and its dosage forms is carried out, as a rule, using HPLC.</p></sec><sec><title>Conclusion</title><p>Conclusion. An analysis of the literature has shown that this substance is unstable. Therefore, this feature of pantoprazole must be considered when choosing excipients when developing a dosage form. The preferred method for analyzing pantoprazole preparations is HPLC, since it is possible to determine the substance in the presence of other compounds, which will allow one to control the quantitative content and stability of pantoprazole in the preparation.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пантопразола натрия сесквигидрат</kwd><kwd>физико-химические свойства</kwd><kwd>методы анализа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pantoprazole sodium sesquihydrate</kwd><kwd>physical and chemical properties</kwd><kwd>methods of analysis</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">Пантопразол.
