Could a cheap, old and boring drug be a coronavirus treatment?

First, we tried the antimalarial drug hydroxychloroquine.
Then we tested the antiviral drug remdesivir. But new UK research gives the strongest indication yet we may have found a useful treatment for COVID-19.
This time it’s an old anti-inflammatory drug, dexamethasone, which has been described as “cheap”, “old” and “boring”.
Preliminary results from a clinical trial just released indicate the drug seems to reduce your chance of dying from COVID-19 if you’re in hospital and need oxygen or a machine to help you breathe.
