Cardiac safety and potential efficacy: two reasons for considering minocycline in place of azithromycin in COVID-19 management

Currently, there is no effective therapy for COVID-19, and several approaches are under investigation. Nevertheless, some drugs are used off-label despite the absence of clear data on their effectiveness.
