Conclusions: This is the first systematic review up to date related to the therapeutics used in COVID-19 patients. Only forty-one research articles on COVID-19 and therapeutics were found eligible to be included, most conducted in China, corticosteroid therapy was found to be the most used medicine in these studies.
