This article discusses the role of various respiratory viruses in the development of bronchial asthma and in triggering its exacerbation. It covers the pathogenetic mechanisms underlying virus-induced bronchial asthma and the importance of interferons for disease control. We summarized the results of international and Russian studies analyzing the utility of type 1 interferons for children and adults with virus-induced asthma exacerbations. Combination drugs containing recombinant α2b interferon plus α-tocopheryl acetate plus ascorbic acid have demonstrated their efficacy in the prevention and treatment of virus-induced asthma exacerbations in routine clinical practice. Moreover, these drugs were safe and well tolerated by patients, which opens new prospects for patients with virus-induced asthma.
