Use of mucoactive agents as a part of combination therapy can reduce the frequency of COPD exacerbations. This article systematizes published data on the safety and clinical efficacy of erdosteine as an additional remedy to standard COPD therapy. Erdosteine is an orally administered mucoactive drug with antioxidant and anti-inflammatory properties. Its use reduces the adhesion of pathogenic bacteria and increases the efficacy of antibacterial drugs. An important peculiarity of erdosteine is its potential use both as a preventative therapy for COPD exacerbations and as a modifier of exacerbation symptoms. During COPD exacerbations, adjunctive use of this drug is accompanied by rapid relief of clinical manifestations and a shortened acute phase of the disease. Long-term use of erdosteine in patients with COPD has demonstrated its superior efficacy and safety comparatively to other mucolytics, with a reduction in exacerbation frequency and an increase in the time to first exacerbation. These aspects are highly actual for the combination therapy of COPD patients in terms of the prevention of exacerbations and their treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Обострения хронической обструктивной болезни легких (ХОБЛ) приводят к быстрому снижению функции легких, ухудшению состояния здоровья, госпитализации, повышению связанной с заболеванием смертности. Применение мукоактивных препаратов в составе комплексной терапии может уменьшать частоту обострений ХОБЛ. В данной статье систематизированы опубликованные данные о безопасности и клинической эффективности использования эрдостеина в дополнение к стандартной терапии ХОБЛ. Эрдостеин – пероральный мукоактивный препарат с антиоксидантными и противовоспалительными свойствами, при приеме которого уменьшается адгезивность патогенных бактерий и увеличивается эффективность антибактериальных препаратов. Важная особенность эрдостеина – возможность его приема и как средства профилактической терапии обострений ХОБЛ, и как модификатора симптомов обострения. При обострении ХОБЛ дополнительное применение этого препарата сопровождается быстрым купированием клинических проявлений, сокращением временно́го интервала острого периода. При долгосрочном применении эрдостеина у пациентов с ХОБЛ продемонстрированы его преимущества в эффективности и безопасности по сравнению с другими муколитиками, установлены снижение частоты обострений и увеличение периода до первого обострения. Эти аспекты крайне актуальны для комплексной терапии пациентов с ХОБЛ с позиций профилактики обострений и их лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic obstructive pulmonary disease</kwd><kwd>mucolytic therapy</kwd><kwd>erdosteine</kwd><kwd>exacerbation of chronic obstructive pulmonary disease</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хроническая обструктивная болезнь легких</kwd><kwd>муколитическая терапия</kwd><kwd>эрдостеин</kwd><kwd>обострение хронической обструктивной болезни легких</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Клинические рекомендации.
