I think you are missing some information. This or a close relative was developed as a heart worm medication for dogs. Soon it was discovered that it was effective against any other dog worms and fleas - maybe some other things. By the time we were introduced to it, it was being prescribed for cats for similar purposes. It was really expensive - the reason being that when you bought some for your animal you were also buying some to send to Africa to fight river blindness.
