The US’s Food and Drug Administration (FDA) has authorised emergency use of the Ebola drug remdesivir for treating the coronavirus.
The authorisation means the anti-viral drug can now be used on people who are hospitalised with severe Covid-19.
A recent clinical trial showed the drug helped shorten the recovery time for people who were seriously ill.
However, it did not significantly improve survival rates.
Experts have warned the drug – which was originally developed to treat Ebola, and is produced by Gilead pharmaceutical company in California – should not be seen as a “magic bullet” for coronavirus.
The drug interferes with the virus’s genome, disrupting its ability to replicate.
