QT Interval Prolongation in COVID-19 Patients on Methadone Treatment

As a result of a widespread infection named coronavirus disease 2019 (COVID-19), there has been a critical request in the world for medications. Up to now, there are no proved effective therapeutic medicines for COVID-19. New medicines and immunizations will take time to be developed and disseminated to patients. Because of variables such as the history of prescription for other infectious diseases, availability, and relatively low cost (1), there has been increasing intrigue about the use of existing medications such as chloroquine (CQ) and hydroxychloroquine (HCQ) as potential treatments for this disease (2) or prophylaxis against COVID-19 (3). For instance, some overviews indicate that hydroxychloroquine is significantly associated with viral load reduction/disappearance in patients with COVID-19, and its impact is fortified by azithromycin (4).
