Experts in the UK say a cost effective and widely available drug can help save the lives of seriously ill COVID-19 patients.
The drug, dexamethasone, a steroid, has been around since the early 1960s, and is usually given in low doses to patients with severe asthma, allergies and painful/swollen joints. It is also used to treat autoimmune conditions, such as systemic lupus erythematosus and rheumatoid arthritis.
Dexamethasone’s effect on inflammation and our immune systems is what is believed to make it useful in treating patients with severe COVID-19 infections.
The drug is part of the RECOVERY Trial, the largest clinical trial to date aiming to identify treatments that may be beneficial for COVID-19 patients.
As part of the trial, researchers studied the effect of dexamethasone in 2,000 patients and compared that to the outcomes in 4,000 patients who did not receive it.
Dexamethasone was found to cut the risk of death by a third for patients on ventilators. For those on oxygen, it cut deaths by a fifth. This equates to one life saved for every eight on ventilators and every 20-25 treated with oxygen.
One of the biggest benefits of dexamethasone is that it is not cost prohibitive, meaning it could be pivotal for treating COVID-19 in poorer countries.
