Remdesivir

The drug Remdesivir is said to have clear cut potential to treat Covid-19. It improves the speed of recovery of the patients affected by the virus. However, it was seen to be of limited  benifits for patients who required mechanical ventilation.

The drug Remdesivir, is developed by Gilead which is a US company.
It was developed to treat Ebola. It works by attacking the enzymes required by the virus to replicate inside our cells. Hence, for the severe cases it is not so effective as the virus has already replicated to an extent. While in the early stage of Covid-19, the drugs kills the enzymes that help in replication of the virus hence, it is proved to be very effective.

The US has bought up almost the entire global supply of it and stocked it for next 3 months.
