Метанол и искусственная вагинальная жидкость (ИВЖ) pH 4.1 выбраны в качестве растворителей, валидация метода проведена для различных параметров. Вориконазол показал более высокую абсорбцию при 256 нм как в метаноле, так и в ИВЖ pH 4.1. Линейность, точность и правильность в качестве аналитических параметров изучены в соответствии с принципами Международной конференции по гармонизации (ICH). Линейный отклик, полученный в диапазоне концентраций 10–50 мкг/мл в метаноле и ИВЖ pH 4.1, следует закону Бера с коэффициентами корреляции 0.998 для метанола и 0.999 для ИВЖ pH 4.1. Точность и повторяемость в пределах 98–102% указывают на высокий доверительный интервал. LOD для вориконазола в метаноле 2.55 мкг/мл, в ИВЖ pH 4.1 — 2.00 мкг/мл; LOQ в метаноле 7.75 мкг/мл, в ИВЖ pH 4.1—6.08 мкг/мл. Метод можно применять для расчета эффективности захвата наноструктурированного липидного носителя, загруженного препаратом, и содержания препарата в таблетках. </p></abstract><trans-abstract xml:lang="en"><p>The present work aimed to develop a simple analytical method and validate the same for the estimation of Voriconazole using ultraviolet spectrophotometry. Methanol and artificial vaginal fluid (AVF) pH 4.1 were chosen as solvents for the development of the analytical method and the validation of the method was done for the different parameters. Voriconazole showed higher absorbance at 256 nm both in methanol and AVF pH 4.1. Linearity, precision, and accuracy as the analytical parameters were studied as per the International Conference of Harmonization (ICH) guidelines. The concentration range of 10–50 μg/mL in methanol and AVF pH 4.1 showed a linear response and followed Beer’s law with coefficient correlation values of 0.998 for methanol and 0.999 for AVF pH 4.1. The results for the accuracy and the repeatability parameter presented values that lie within the range of 98–102%, indicating a higher confidence interval. Regarding the method's sensitivity, the LOD for the drug in methanol and AVF pH 4.1 was found to be 2.55 and 2.00 μg/mL, respectively. The LOQ for the drug in methanol was 7.75 μg/mL and in AVF pH 4.1 was  6.08 μg/mL. The proposed, developed and validated method was simple, sturdy, cost-effective, and timesaving. The method could be further applied to calculate the entrapment efficiency of the drug-loaded nanostructured lipid carrier and tablet drug content.   </p></trans-abstract><kwd-group xml:lang="ru"><kwd>вориконазол</kwd><kwd>УФ-видимая спектроскопия</kwd><kwd>метанол</kwd><kwd>искусственная вагинальная жидкость pH 4.1</kwd><kwd>валидация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>voriconazole</kwd><kwd>UV-Visible spectroscopy</kwd><kwd>methanol</kwd><kwd>artificial vaginal fluid pH 4.1</kwd><kwd>validation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">The authors would like to acknowledge Mylan Hyderabad, for the sample gift  of Voriconazole.
