С учетом патофизиологических особенностей заболевания, характеризующегося частым наличием гипериммунного ответа на патоген, определённый потенциал в этом плане заложен в средствах иммуносупрессивного действия (СИСД). Наиболее перспективными из них признаны иммунобиологические препараты, обладающие прецизионным иммуносупрессивным действием, к которым относятся моноклональные антитела (МКАТ). Однако появились единичные работы, предлагающие использование цитостатиков, в том числе и в ингаляционном виде, от применения которых с целью лечения воспаления дыхательных путей (ДП), как хорошо известно, отказались еще в 1990-е годы в силу их малой эффективности и сопряженности с целым рядом грозных побочных эффектов. Определение целесообразности использования данной группы препаратов с современных позиций – цель обзора. Рассмотрены возможности и некоторых других СИСД, в том числе и иммунобиологических препаратов, составляющих тренд в современной медицине. Дан анализ эффективности воздействия различных подгрупп СИСД, в том числе и при ингаляционном их введении в ДП. Отражены методы и подходы их использования, преимущества и недостатки, оценка целесообразности и перспективы их применения. Эффективность цитостатиков и ингибиторов кальциневрина при лечении воспаления ДП при COVID-19 остаётся не подтвержденной и бесперспективной. Перспективными средствами в этом плане являются биологические препараты, включая моноклональные антитела и средства пуринергической регуляции.</p></abstract><trans-abstract xml:lang="en"><p>Despite numerous efforts of healthcare, the incidence of COVID-19 and its fatal complications remains unacceptably high. As COVID-19 pathophysiology is notable for an uncurbed immune response, its treatment protocols routinely include immunosuppressive drugs such as corticosteroids, cytostatic drugs, calcineurin inhibitors, and monoclonal antibodies. Here we review the efficacy of the latter 3 drug classes, in particular inhalation preparations, in COVID-19 treatment and SARSCoV-2 elimination as well as their potential advantages and drawbacks. Efficacy of cytostatic drugs and calcineurin inhibitors in the treatment of airway inflammation in COVID-19 remains unconfirmed. Promising agents in this regard are biologics, including monoclonal antibodies and purinergic agents.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>воспаление</kwd><kwd>цитокины</kwd><kwd>цитостатики</kwd><kwd>ингибиторы кальциневрина</kwd><kwd>иммуносупрессоры</kwd><kwd>моноклональные антитела</kwd><kwd>пуринергическая регуляция</kwd><kwd>аэрозоль</kwd><kwd>регуляторные Т-клетки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>inflammation</kwd><kwd>cytokines</kwd><kwd>cytostatic drugs</kwd><kwd>calcineurin inhibitors</kwd><kwd>immunosuppressive drugs</kwd><kwd>monoclonal antibodies</kwd><kwd>purinergic agents</kwd><kwd>aerosols</kwd><kwd>regulatory T cells</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">Huang C, Wang Y, Li X, Ren L, Zhao J, Hu Y, Zhang L, Fan G, Xu J, Gu X, Cheng Z, Yu T, Xia J, Wei Y, Wu W, Xie X, Yin W, Li H, Liu M, Xiao Y, Gao H, Guo L, Xie J, Wang G, Jiang R, Gao Z, Jin Q, Wang J, Cao B.
