Would really have to look at the particular product. I know some medicated salts mix particular probiotics, like KoiZyme, and some bentonite or montmorillonite clay into the salt, but I think there are also always those pond products out there that are just good at selling a worthless product. Those medicated, or some how "special", pond salts actually are quite expensive and all ya can do is trust the marketing on the label, which can be quite deceitful.
Personally, if the goal is to increase salinity, then just get the cheap stuff that works just as good. If ya want to add something like KoiZyme or clay into the water, then get those products specifically.
There might be a brand of expensive medicated salt that is quite effective, but, generally, my rule is to pay attention to what other, more experience folk, are using rather than trusting the label on a product.
