Why do studies have the default assumption that thyroxine should be used?

[Guest guest]

Why is thyroxine the default treatment for hypothyroidism instead of

Armour? Why do all the studies aim to prove that Armour has an

advantage over thyroxine (with apparently negative results)?

Surely Armour should be the assumed default drug of choice simply on

the grounds of it being physiologicaly more similar to that of the

thyroid output (all the secreted hormones as opposed to just one), and

it should be used for treatment unless the studies prove that

THYROXINE has the advantage?

If everything is equal for thyroxine and Armour: studies show that

thyroxine gives no more benefit for quality of life, improved

cognitive ability etc. than Armour. The safety and consistency are the

same. bla bla bla. Then why is it that thyroxine should REMAIN the

treatment of choice? Simply because it was the first kid on the block?

Or are there advantages thyroxine has that Armour doesn't (I don't

think money/cost should really be counted as who can put a price on

peoples health?)

In actual fact, the fact that patients prefer physiological doses of

Armour should sway the argument to the side of Armour, surely?
