Efficacy and safety of the antileukotriene drugs: relevant data. RAACI experts conclusion

In many countries of the world and in Russia, in particular, the pharmacological use of antagonists of cysteinyl receptors LT1 (CysLTR) is a long­-proven and well­-proven pharmacotherapy of bronchial asthma (BA) and allergic rhinitis (AR) in adults and children. Among antileukotriene drugs the most commonly used medication for the treatment of these diseases is the original montelukast, which is considered a safe drug associated with the appearance of only a few adverse reactions, usually not differing in type and frequency from those that occur with placebo. Currently, there are a large number of generics of montelukast, therefore, practitioners have many questions regarding the benefits and risks of montelukast therapy for patients with BA and AR. In 2020 FDA (Food and Drug Administration USA) analyzed the risk of adverse events during Montelukast treatment and indicated them on the packaging of the drug (original montelukast and its generics). This contributed to the creation of an expert commission to study this issue and form an expert opinion, which is demonstrated in our publication.
