ABSTRACT
The pandemic caused by infection with the new SARS-CoV-2 coronavirus has brought unprecedented mortality. Its high contagiousness and lethality, especially in vulnerable patients, has led to an urgent search for drugs that have a potential benefit in controlling this pandemic. Research to develop a new drug involves long periods of experimentation. For this reason, scientists have focused on testing the use of pre-existing drugs, even when their initial purpose is not an antiviral effect. In this review, we will analyze the evidence of the different proposed treatment options, with emphasis on their mechanism of action and the benefits found in observational studies. © 2020 Comunicaciones Cientificas Mexicanas S.A. de C.V..
