top Why do dewormers have different amounts of the same ingredients?

Differences in ingredient amounts do not necessarily mean differences in how well products work. For instance, even at a lower dose of praziquantel, ZIMECTERIN Gold is just as effective — more than 99 percent effective — against natural tapeworm (Anoplocephala perfoliata) infections.1

Why use more praziquantel than necessary?
