Thanks very much for that! Very true about all the permutations.

Hopefully in about one hundred years all the right studies will have been done and someone will benefit - hehe!! The trouble is in the past it has typically taken about ten years after research was published for it to be instituted into medical textbooks and into the educational programs of training medical students. No wonder it takes so long for change to happen. Hopefully that time lapse is beginning to shorten these days with more access by interested thinking everyday people (non-medical persons) to research information as it is released.

I think Dexamethasone potency is one good example of this tardiness in disseminating accurate updated data. Most of the corticosteroid charts seem to still state that 0.75mg Dex = 20mg Hydrocortisone, although I have found one website that states 25-80 times the potency of Hydrocortisone. So at least it states the higher range unlike some; but how broad is that??? I think the higher potency of Dex was mooted as long ago as 1977 possibly even earlier.
