В настоящее время физико-химические методы анализа активно используются для определения содержания лекарственных веществ в биологических жидкостях. Особенно широкое распространение приобрела высокоэффективная жидкостная хроматография с различными способами детектирования. Одной из наиболее сложных практических задач является хроматографическое разделение так называемых слабоудерживаемых соединений – лекарственных веществ, плохо удерживаемых на хроматографической колонке. Одними из таких веществ являются валганцикловир и ганцикловир.</p></sec><sec><title>Цель</title><p>Цель.

Currently, physicochemical methods of quantification are actively used to determine the content of drugs in biological fluids. High-performance liquid chromatography with various detection methods is particularly widespread. One of the most difficult practical tasks is the chromatographic separation of so-called poorly retained compounds – drug substances poorly retained on the chromatographic column. Valganciclovir and Ganciclovir are among such substances.</p></sec><sec><title>Aim</title><p>Aim. The aim of this study is to develop a method for valganciclovir and ganciclovir in human plasma by high performance liquid chromatography with tandem mass-spectrometry (HPLC-MS/MS) for pharmacokinetic studies.</p></sec><sec><title>Materials and methods</title><p>Materials and methods.

This method was validated by next parameters: selectivity, matrix effect, calibration curve, accuracy, precision, recovery, lower limit of quantification, carry-over and stability.</p></sec><sec><title>Conclusion</title><p>Conclusion. The method of the determination of valganciclovir and ganciclovir in human plasma was developed and validated by HPLC-MS/MS. The linearity in plasma sample was achieved in the concentration range of 5.00–1000.00 ng/ml for valganciclovir and 50.00–10000.00 ng/ml for ganciclovir. Method could be applied to valganciclovir and ganciclovir determination in plasma for PK and BE studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>валганцикловир</kwd><kwd>ганцикловир</kwd><kwd>плазма</kwd><kwd>ВЭЖХ-МС/МС</kwd><kwd>валидация</kwd><kwd>биоэквивалентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>valganciclovir</kwd><kwd>ganciclovir</kwd><kwd>plasma</kwd><kwd>HPLC-MS/MS</kwd><kwd>validation</kwd><kwd>bioequivalence</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">Карпов И.
