В качестве растворителя использован смешанный фосфатный буферный раствор (pH 6.8) в соответствии с принципами экологичности. Спектрофотометрический анализ проведен в диапазоне 200–400 нм. Максимум поглощения зарегистрирован при 237 нм. Наблюдается линейная зависимость (r = 0.998), указывающая на соответствие закону Бера в диапазоне концентраций 10–30 мкг/мл. Степень извлечения вонопразана 98.01– 101.25 масс.%, что подтверждает точность метода. Точность метода также подтверждена процентным относительным стандартным отклонением, которое оставалось в пределах допустимых значений. Обеспечено соответствие строгим требованиям ICH Q2 (R1). Оценка экологичности метода проведена с использованием аналитической экошкалы, метрик AGREE и GAPI. Результаты оценки экологичности и аналитических достоинств подтвердили надежность метода и его пригодность в качестве улучшенной альтернативы для анализа вонопразана.</p></abstract><trans-abstract xml:lang="en"><p>This study aimed to develop a novel, rapid, and precise UV spectrophotometric method for quantifying Vonoprazan in both pure and tablet dosage forms. On the basis of an extensive evaluation of solubility, stability, toxicity, and carcinogenicity, and in line with eco-friendly approaches, a mixed phosphate buffer solution (pH 6.8) was employed as the solvent. Spectrophotometric analysis was performed within the 200–400 nm wavelength range. A distinct absorption maximum was identified at 237 nm, and strong linear relationship (r = 0.998) was observed, indicating compliance with Beer’s law within the 10–30 μg/mL concentration range. Furthermore, the recovery of Vonoprazan ranged from 98.01 to 101.25% (w/w), confirming the method’s accuracy. Precision of the method was confirmed by the percentage relative standard deviation, which remained within acceptable limits as per guidelines. Compliance with the stringent requirements of ICH Q2 (R1) was ensured throughout the entire evaluation process. Assessment of the method’s greenness was carried out using the Analytical Eco-Scale, AGREE metrics, and GAPI. Findings from the greenness evaluation and analytical merits confirmed the method’s reliability and supported its suitability as an improved alternative for Vonoprazan analysis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вонопразан</kwd><kwd>принципы “зеленой” химии</kwd><kwd>ультрафиолетовая спектрофотометрия</kwd><kwd>ICH Q2 (R1)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Vonoprazan</kwd><kwd>Green method</kwd><kwd>ultraviolet spectrophotometry</kwd><kwd>ICH Q2 (R1)</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">The authors are thankful to the management of SRM College of Pharmacy, Faculty of Medicine and Health Sciences, SRM Institute of Science and Technology, Kattankulathur, for providing the facilities to carry out the research work successfully.</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">Garnock-Jones, P.
