Half-life is 12-hours, I think. Multiple doses might be needed, which is not a big deal. The patients right now are getting doses several times a day of the various drugs that are keeping them in a medically-induced coma, etc. So something that is keeping people as outpatients instead of being admitted -- or that would keep hospitalized people from having to be moved to the ICU -- not a big deal to keep them on an IV drip instead of a ventilator. Outpatients could go to a clinic daily.

Who knows? We don't. We'll have to see how the next round of testing goes.
