Exactly. It is a pretty old strategy
Take an old out of patent drug approved drug, slightly alter the molecule and resubmit it for approval claiming it is improved.
It may not perform any better than the old drug or it may perform worse, but it can be marketed as long as they can show it is safe and effective.
Since they have slandered Ivermectin to the point that a great percentage of the population believe it is only safe for live stock they can easily get them to pay thousands of dollars per dose for a nearly identical drug.
Quercetin, Zinc, D3, C, and NAC works just fine, thank you.
I’m not planning on supporting big pharma, I’d rather buy ammo.
I’ve seen them do that with antihistamines many times over the years.
