Abstract

Antidepressants (ADs) include drugs of various pharmacological groups, which are mainly used for the treatment of mental disorders (major depressive disorder, obsessive-compulsive disorder, social phobia, panic disorder, generalized anxiety disorder, post-traumatic stress disorder), chronic pain and addiction diseases. Chronic use of ADs can lead to the development of cardiotoxic adverse drug reactions (ADRs). The most important cardiotoxic AD-induced ADRs are prolongation of the QT interval, ventricular tachycardia of the "pirouette" type (Torsades de Pointes - TdP). This narrative review analyzes and summarizes the results of studies on pharmacokinecis and pharmacogenetics of ADs on QT interval prolongation and updates physicians' knowledge of the risk of developing AD-induced TdP in patients with psychiatric disorders.
