Remdesivir as a drug attracted a very serious consideration of whole Globe in treatment of the pandemic disease COVID-19. More recently published in-vitro inhibition activity and in-vivo case studies were showing promising clinical results and outcome of effective inhibition of SARS-CoV-2 virus by the use of remdesivir. However at the same time, use of the remdesivir showed substantial detrimental adverse events in patients which needs a special attention during treatment course of COVID-19. Thus, the use of remdesivir in treatment of COVID-19 is having current international interest although some more clinical evidences are still necessary in order to understand the actual efficiency and mechanism of remdesivir against COVID-19. In view of this, the present literature study spotlight the current ongoing research related to use of remdesivir which includes (i) pharmacology of remdesivir, (ii) mechanism of action of remdesivir (iii) in-vitro inhibition of remdesivir against SARS-CoV-2 virus, (iv) in-vivo analysis and clinical use of remdesivir against COVID-19. Finally possible adverse events (of use of remdesivir) are also discussed considering the pharmacovigilance concern.
