The Association of American Physicians and Surgeons (AAPS) wrote a letter to Republican Arizona Governor Doug Ducey urging the wider use of hydroxychloroquine,proven 91% effective, based on data they have collected.

So... why is there resistance to hydroxychloroquine?
Only because President Trump supports its use.

Most patients with hydroxychloroquine recover within 5 to 6 days.

The next closest is remdesevir, which cures people in 11 days, is more expensive, and can only be administered by IV in a hospital. Whereas hydroxychloroquine can be taken orally, usually in combination with zinc (that inhibits virus reproduction), and Azithromycin (a strong antibiotic). Hydroxychloroquine can be taken to prevent Covid-19 infection, can be taken early into symptoms of Covid-19, that prevents severe symptoms and hospitalization. And in multiple cases, several of which I've linked here, people were literally at death's door with Covid-19, and made a recovery within hours of hydroxychloroquine being administered.

It's highly suspicious that it's consistently Democrat governors and political leaders who oppose the use of hydroxychloroquine. Democrats who would rather let 2,000 people a day die than credit President Trump with a good decision in supporting its use.
Although the governor in this case is a Republican.

The only other reason I've seen speculated as a resistance to hydroxychloroquine is that it is inexpensive and not profitable to drug manufacturers, and apparently anyone can produce it, so it is not exclusively owned by any drug manufacturer. Again, hydroxychloroquine has been in use since 1944, and FDA approved since 1955, and highly prescribed for many years to patients with malaria, lupus, and lyme disease. Not just for 5 or 6 days as it is with Covid-19 patients, but is prescribed for years to people wih these lifelong chronic conditions, with no noteworthy side effects, which prescribing physicians cite as extremely rare.

A prescription for hydroxychloroquine is less than $20.00. So possibly the search is on for a more expensive patented drug that does the same job. Remdesevir fits that bill. Keeping people on ventilator machines is also more profitable.
