Drug repositioning is a strategy that identifies new uses of approved drugs, to treat conditions different from their original purpose. With the advance of COVID-19 and the declaration of a pandemic; It has become the closest alternative to slow the advance of the virus. Antimalarial, antiviral drugs, antibiotics, glucocorticoids, monoclonal antibodies, among others, are being studied; his findings, although preliminary, could establish a starting point in the search for a solution. In this article, we present a selection of drugs, of different classes and with potential activity to combat COVID-19, whose trials are ongoing; and as proofs of concept, double blind, event-driven add-on, would allow proposing research that generates results in less time and preserving the quality criteria for drug development and approval by regulatory agencies.
