you know, dexamethasone and hydroxychloroquine are used for many of the same purposes, and the success of the former appears to be that it is succeeding in reducing those cytokine storms that identified hydroxychloroquine as a potential treatment, for extremely ill patients.

it does sometimes happen that a specific formulation of a class of drugs may be more effective in a certain scenario, but if it is the case that dexamethasone is succeeding and hydroxycholoroquine is failing then some kind of reasoning as to why that is would be useful in demonstrating the point.

as it is, i'm not sure that small scale trials for the success of this new drug should be treated much differently than small scale trials for the success of the previous one were, and i'd not be at all surprised if clinical trials for dexamethasone end rather similarly to ones for hydroxycholoroquine.

there might be some specific difference in delivery or something; i'm not discounting it. i'm just a little skeptical, given that they appear to be prescribed interchangeably for most if not all of their clinical uses.
