Remdesivir in COVID-19

Remdesivir (also GS-5734) is a monophosphoramidate prodrug of an adenosine analogue that has a broad antiviral spectrum including filoviruses, paramyxoviruses, pneumoviruses, and coronaviruses. In vitro, remdesivir inhibits all human and animal coronaviruses tested to date, including SARS-CoV-2.

 Intravenous remdesivir was studied for treatment of Ebola virus disease, in which it was adequately tolerated but less effective than several monoclonal antibody therapeutics,and has been used on the basis of individual compassionate use over the past several months in patients with COVID-19 in some countries.

Conclusion –

Inconclusive evidence in support of Remdesivir.

Can be used in research context but its too early to call it as a CURE for COVID-19.
