Mecanismos de acción de agentes propuestos para el tratamiento farmacológico específico de la infección por SARS-CoV-2

Abstract

Since the beginning of the pandemic by SARS-CoV-2, the pathogen responsible for COVID-19, many of the therapeutic options for its management have been under constant revision, in order to verify their safety and efficiency. Knowledge of the viral structure and pathogenesis make it possible to determine the molecular pathways that may be targeted with current available drugs. The experience with these drugs comes mainly from infections caused by SARS-CoV and MERS-CoV, in vitro studies with SARS-CoV-2 that yield variable results, and clinical experience that does not ensure effectiveness and safety of such drugs. To date, it has not been possible to elucidate a specific treatment scheme, because of the constant release of evidence that challenges the usefulness of the proposed drugs. This has motived us to continue seeking for an effective strategy that allows to manage this pandemic in a safe and efficient manner, so that therapeutic benefit surpasses the related adverse drug reactions that can occur. The following review aims to showcase the evidence available to date by defining the activity of each drug based on its mechanism of action.
