There have been a couple reports of arthritis drugs (Rheumatoid Arthritis?) being tried (with some success?) for treating Covid-19 cases. But drug names or types were not stated. Methotrexate? Leflunomide? The "Biologics?" If these drugs' sort of general immune system suppression function is working against Covid-19, that would suggest the "Cytokine Storm" explanation of this Coronovirus' lethality?
(Apologies for all the ?'s and lack of search on this.)
