Coronavirus: Dexamethasone proves first life-saving drug

A cheap and widely available drug can help save the lives of patients seriously ill with coronavirus, BBC reports.

The low-dose steroid treatment dexamethasone is a major breakthrough in the fight against the deadly virus, UK experts say.

The drug is part of the world's biggest trial testing existing treatments to see if they also work for coronavirus.

It cut the risk of death by a third for patients on ventilators. For those on oxygen, it cut deaths by a fifth.

Had the drug had been used to treat patients in the UK from the start of the pandemic, up to 5,000 lives could have been saved, researchers say.

And it could be of huge benefit in poorer countries with high numbers of Covid-19 patients.

In the trial, led by a team from Oxford University, around 2,000 hospital patients were given dexamethasone and were compared with more than 4,000 who did not receive the drug.

For patients on ventilators, it cut the risk of death from 40% to 28%. For patients needing oxygen, it cut the risk of death from 25% to 20%.

Chief investigator Prof Peter Horby said: "This is the only drug so far that has been shown to reduce mortality - and it reduces it significantly. It's a major breakthrough."

Lead researcher Prof Martin Landray says the findings suggest that for every eight patients treated on ventilators, you could save one life.

For those patients treated with oxygen, you save one life for approximately every 20-25 treated with the drug.

"There is a clear, clear benefit. The treatment is up to 10 days of dexamethasone and it costs about £5 per patient. So essentially it costs £35 to save a life. This is a drug that is globally available."

Prof Landray said, when appropriate, hospital patients should now be given it without delay, but people should not go out and buy it to take at home.

Dexamethasone does not appear to help people with milder symptoms of coronavirus - those who don't need help with their breathing.
