COVID-19: treatments and the potential for cardiotoxicity.

A wide range of medications including antimalarial preparations (chloroquine, hydroxychloroquine), macrolide antibiotics (azithromycin) and the interleukin-6 inhibitor (tocilizumab) may be effective in treating patients with coronavirus disease 2019 (COVID-19). Such agents may be associated with cardiotoxicity, and the purpose of this brief review is to draw attention to potential areas of pharmacovigilance. These include prolongation of the QT-interval and the development of occult cardiomyopathy.
