Hi Donna,
You're correct: nicotinamide and niacinamide are identical. Odd that you can't find one but the other is available.
The other drugs are beyond my ken, I'm afraid. I'm a homeopath, and I rely on knowing my remedies well, not on studying all the tangled interactions of drugs. Perhaps you can find an "integrative vet" who keeps a foot in two canoes to help you sort this out. Too unstable for me.
Good luck and thanks for stopping by the Natural Path!
