Some here have questioned what has happened to the UK tests for drugs that might help CV 19 patients.
Reminding you this site does not offer medical advice, I read that the UK trials have produced some good outcomes for the cortico steroid dexamethasone used on some pandemic patients.In the case of patients on ventilators one third benefited from this drug, and for patients given oxygen one fifth compared to patients not given it. Less ill patients did not benefit.
This drug is readily available from a range of manufacturers. It was first produced by Merck but now is widely manufactured around the world. It will be interesting to see what use doctors make of this option in the light of the findings of the trials.
