Abstract:
The use of antiviral drugs represents an important progress in the therapeutic management of COVID-19, leading to a substantial reduction of SARS-CoV-2-related complications and mortality. In immunocompetent host, peak viral replication occurs around the symptom's onset, and it prolongs for 5 to 7 days that is the window of opportunity for giving an antiviral. Accordingly, early and rapid diagnostic of the infection in the outpatient clinic is essential as well as the availability of oral agents that can be easily prescribe. Remdesivir has demonstrated its efficacy in hospitalized patients requiring oxygen support and in mild/moderate cases to avoid the hospitalization, however, the intravenous administration limits its use among outpatients. Molnupiravir and nirmatrelvir/ritonavir are potent oral antiviral agents. In the present review we discuss the potential targets against SARS-CoV-2, and an overview of the main characteristics and clinical results with the available antiviral agents for the treatment of SARS-CoV-2.
