As the Louisiana Dr says, time will tell. Right now it appears that the sampling population is rather small, while the results appear nearly spectacular. Caution lights are bound to flash.
The cocktail mix you mention I presume includes the Azithromycin and zinc. The Azithromycin {Z-pack} is a logical companion to an antiviral respiratory therapy. The coronavirus attacks the lungs and weakens them which makes them vulnerable to bacterial pneumonia.
Many people do not realize that they carry various pneumonia pathogens in their lungs for whatever reason. Their natural immune system holds the threat at bay, but a weakening of the organism increases the risk. Antibiotics are fairly easy to get to the lungs due to a profusion of blood flowing through there to exchange O2 and CO2 constantly.
The bronchial tubes are different; for some time the best drugs to reach the bronchial tubes that are infected was sulfa drugs {Sulfamethoxazole, Trimethoprim, Bactrim} but after a short while the cure got about as bad as the disease in some respects. {The same held true for urinary tract infections.} Newer antibiotics are overcoming these shortcomings and Azithromycin is apparently one of them. Early CoViD-19 infections were ID'd as pneumonia and bronchitis until culturing was done, so Azithromycin seems a reasonable companion drug to an antiviral.
As for the zinc - well, I suppose it is anyone's guess. I think zinc has been demonstrated to somewhat block virus access to penetrating the body's {pulmonary} cells; there is evidence that high levels of zinc can prove destructive to the organism as a whole. Given many people's propensity to reason that, if 10 mg of zinc can be helpful, they will take a half of a pound, it is best to caution folks to approach that very cautiously or just leave it alone.
To get good amount of zinc without getting too much is to a eat a couple handfuls of pumpkin seeds a day. I roast them in oven, very tasty.
