Coronavirus: What is dexamethasone and how does it work?
An anti-inflammatory drug called dexamethasone has been hailed as a ground-breaking treatment for hospital patients seriously ill with Covid-19.
The drug does not work on people with milder symptoms, and suppressing their immune system at this point would not be helpful.According to the scientists who carried out the trials, one in three deaths could be prevented among patients on ventilators.There was no significant benefit for patients who were not receiving respiratory support.The results come from the Recovery trial, conducted by the University of Oxford.
The Department of Health and Social Care says the drug has also been added to the government's parallel export list, which bans companies from buying medicines meant for UK patients and selling them on for a higher price in another country.The World Health Organization has welcomed the trial results, saying more therapies are now needed for milder symptoms.In many African nations, for example, the drug costs less than two dollars.
