Для количественной оценки обоих препаратов могут быть применены три спектрофотометрических метода, основанных на соотношении перекрывающихся УФспектров их бинарной смеси. Вычислена первая производная (DR1 ) отношения спектров, измерены амплитуды при 268.7 и 237.4 нм для TRA и PAR. Среднее центрированное отношение (MCR) спектров оценено путем измерения спектров MCR при 279 и 241.5 нм для TRA и PAR. Метод двух длин волн (DW) применен путем измерения разницы в поглощении при 224.1 и 268.5 нм для определения TRA и при 248 и 285.4 нм для определения PAR без каких-либо помех. Вышеперечисленные спектрофотометрические методы могут быть использованы для оценки ТRА в линейном диапазоне 10–110 мкг/мл. PAR может быть оценен в диапазоне 1–25 мкг/мл. Методы успешно применены для анализа комбинированной лекарственной формы и нерасфасованных порошков TRA и PAR, а также валидированы в соответствии с принципами Международной конференции по гармонизации (ICH). Результаты статистически сопоставлены с данными, полученными с помощью ранее описанных методов. Существенной разницы в точности и воспроизводимости не наблюдалось. </p></abstract><trans-abstract xml:lang="en"><p>UV spectroscopy of tramadol (TRA) and paracetamol (PAR) shows substantial spectral overlap, which is a challenge for their simultaneous determination without preliminary separation. Three smart spectrophotometric methods based on the ratio spectra developed from the overlapping UV spectra of their binary mixture can be applied for a quantitative estimation of both drugs. The first derivative (DR1 ) of the ratio spectra was computed, and then the amplitudes were measured at 268.7 and 237.4 nm for TRA and PAR, respectively. The mean centered ratio (MCR) of the spectra was estimated by measuring the MCR spectra at 279 and 241.5 nm for TRA and PAR, respectively. Finally, the dual wavelength method (DW) was applied by measuring the difference in absorbance at 224.1 and 268.5 nm for TRA determination and at 248 and 285.4 nm for PAR determination without any interference. All the above-mentioned spectrophotometric methods can be used to estimate TRA in the linear range of 10–110 µg/mL. Furthermore, PAR can be estimated in the linear range of 1–25 µg/mL. These methods were successfully applied to the analysis of the combined dosage form and bulk powder of TRA and PAR. The methods were validated according to the International Conference on Harmonization (ICH) guidelines, and the obtained results were statistically compared with those obtained by previously reported methods. No significant difference with respect to accuracy and precision was observed. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>трамадол</kwd><kwd>парацетамол</kwd><kwd>спектры соотношения</kwd><kwd>среднее центрирование</kwd><kwd>двойная длина волны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tramadol</kwd><kwd>paracetamol</kwd><kwd>ratio spectra</kwd><kwd>mean centering</kwd><kwd>dual wavelength</kwd></kwd-group><funding-group><funding-statement xml:lang="en">We thank Edanz Group (https://en-author-services.edanzgroup.com/ac) for editing a draft of this manuscript.</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">M.
