A comprehensive review of COVID-19 treatment

Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus strain that caused coronavirus disease 2019 (COVID-19). This novel coronavirus is an emerging global health threat. It caused approximately 140 million confirmed cases, with about 3 million deaths worldwide until April 18, 2021. Although there are two approved medications for this disease, remdesivir and dexamethasone, numerous studies are underway to investigate more therapeutic options. However, so far, most treatments have been supportive, and the clinical efficacy of the suggested drugs is still under consideration. The purpose of this review is to summarize the ongoing treatments, such as several antivirals, convalescent plasma transfusion, and adjunctive medications, with the intent of serving as a clinical guide for the physician and a resource for further evaluations in various clinical trials.
