More and more it seems like doctors are throwing anything and everything at this virus -- are these meds working or is it the fact that people are eventually recovering at the same time doctors are giving up and throwing some kind of remedy at them?
In regard to this drug, it appears to have been prompted by a coincidence observed in China, as the article describes.
The reality is that when dealing with treating an unknown virus, there's a lot of guesswork—and the fact that we're trying a lot of different approaches is good. Pepcid is another one of those drugs that is cheap and readily available; it's even over-the-counter here in America. So if that one works beyond that of a placebo, that might be even better news than if HCQ/zinc works.
There are still over 10,000 people in the hospital with this virus right now in New York. They make a natural testing ground for a virus with no proven treatment. So yes, there is going to be a lot of throwing things against the wall, looking at what little evidence we do have, and seeing what sticks.
