    Snippet: BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiology of COVID-19 pandemic, resulted in significant harm to the affected countries in every aspect of life. The virus infected over 139 million patients and resulted in over 2.9 million deaths until April 16, 2021. New variants of this virus were identified that spread rapidly worldwide. SUMMARY: Remdesivir, a prodrug of adenosine nucleotide analog, is an antiviral with a broad spectrum of activity that was test
    Document: BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiology of COVID-19 pandemic, resulted in significant harm to the affected countries in every aspect of life. The virus infected over 139 million patients and resulted in over 2.9 million deaths until April 16, 2021. New variants of this virus were identified that spread rapidly worldwide. SUMMARY: Remdesivir, a prodrug of adenosine nucleotide analog, is an antiviral with a broad spectrum of activity that was tested on SARS and Middle East respiratory syndrome infections. In vitro studies conducted on SARS-CoV-2 revealed that remdesivir inhibited viral replication with high selectivity index in cell cultures. In vivo studies showed that remdesivir reduced viral load in bronchoalveolar lavage fluid and attenuated pulmonary infiltrates in infected animals. Further, remdesivir showed promising results in terms of clinical improvement, shortening the recovery time, mortality rate, and the duration of oxygen need, despite that some clinical trials did not reveal significant effect on remdesivir use. Several studies showed positive results of remdesivir against the new variants. KEY MESSAGES: Remdesivir showed a promising beneficial effect against new variants of SARS-CoV-2, but more clinical evidence is needed to confirm this effect.
