Possible treatment strategies for COVID-19

There is no specific antiviral treatment for COVID-19. However, knowledge acquired during the SARS and MERS outbreaks, together with the information obtained with COVID-19, have allowed the detection of various therapeutic targets in the virus replication cycle, and in its pathogenesis. The current evidence regarding the leading treatments proposed for COVID-19, reused or experimental, is included through a review of the scientific literature to date. Due to the lack of randomized controlled trials, the following were involved: case reports, case series and review articles. Globally, multiple studies are being carried out in order to identify agents that are effective against COVID-19, upon the following strategic objectives: inhibition of viral entry/fusion (neutralizing antibodies, transmembrane serine protease 2 inhibitors, chloroquine, hydroxychloroquine, and umifenovir); interruption of viral replication (remdesivir, favipiravir, lopinavir/ritonavir and ivermectin), and suppression of excessive inflammatory response (corticosteroids, tocilizumab, and immunoglobulin). There is still no effective and safe treatment against COVID-19; the medications described in this review are given as compassionate drug use, or as part of a clinical trial. Support therapy continues to be COVID-19 management cornerstone.(AU)
