Genetically determined variability in pharmacokinetics and pharmacodynamics may contribute to interindividual differences in treatment efficacy and tolerability, yet it is rarely incorporated into routine prescribing. We report a clinical case of a 54-year-old female patient of Kyrgyz ethnic origin with uncontrolled blood pressure on combination therapy and an adverse reaction (peripheral edema) during amlodipine treatment. Pharmacogenetic testing revealed CYP2C9 *1/*3 (potentially reduced formation of the active losartan metabolite), CYP3A5 *3/*3 (a possible association with an increased risk of amlodipine-related adverse reactions), and CYP2D6 *10/*10 (a potential risk of dosedependent adverse reactions with certain beta-blockers). Therapy adjustment based on the obtained profile (switching from losartan to perindopril in combination with indapamide) was associated with achievement of target blood pressure levels without initiation of triple therapy. Pharmacogenetic information may be considered an additional tool to support antihypertensive therapy selection in selected patients.</p></abstract><trans-abstract xml:lang="ru"><p>В клинической практике при артериальной гипертензии нередко сохраняется недостаточный контроль артериального давления на фоне стандартной антигипертензивной терапии. Одним из факторов вариабельности эффективности и переносимости лечения могут быть генетически обусловленные особенности фармакокинетики и фармакодинамики, редко учитываемые при рутинном назначении препаратов. Представлен клинический случай 54-летней пациентки кыргызской этнической группы с неконтролируемым АД на фоне комбинированной терапии и нежелательным явлением (периферические отеки) при приеме амлодипина. Фармакогенетическое тестирование выявило CYP2C9 *1/*3 (потенциально сниженное образование активного метаболита лозартана), CYP3A5 *3/*3 (возможная ассоциация с повышенным риском амлодипин-индуцированных нежелательных реакций) и CYP2D6 *10/*10 (потенциальный риск дозозависимых нежелательных явлений при применении некоторых бета-адреноблокаторов). Коррекция терапии с учетом полученного профиля (замена лозартана на периндоприл в комбинации с индапамидом) сопровождалась достижением целевых уровней артериального давления без назначения тройной комбинации. Фармакогенетическая информация может рассматриваться как дополнительный инструмент обоснования выбора антигипертензивной терапии у отдельных пациентов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>артериальная гипертензия</kwd><kwd>фармакогенетика</kwd><kwd>персонализированная терапия</kwd><kwd>CYP2C9</kwd><kwd>CYP3A5</kwd><kwd>клинический случай</kwd><kwd>лозартан</kwd><kwd>амлодипин</kwd><kwd>фармакогенетический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arterial hypertension</kwd><kwd>pharmacogenetics</kwd><kwd>personalised therapy</kwd><kwd>CYP2C9</kwd><kwd>CYP3A5</kwd><kwd>clinical case</kwd><kwd>losartan</kwd><kwd>amlodipine</kwd><kwd>pharmacogenetic 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">Mancia G, Kreutz R, Brunström M, et al. 2023 ESH Guidelines for the management of arterial hypertension.
