Here is my cheat sheet for dewormers as you can see some 'families/Drug Classes' are not rotating dewomer as they really are the same family. Also some of the same dewormer can come in different strengths.
This is by no means all inclusive list. Everyone should consult their vet and do their research on a deworming program that fits your horses/circumstances.
