Sometimes you have to watch dated news like this. Synthroid (Abbott) tried to be real slippery about this and finally relented. They were one of the last to actually get FDA approval because of this. They even tried to grandfather themselves in because they claimed Synthroid was bioequivalent to Armour (how stupid do they think we are?).
$ynthroid - the Bill Clinton of thyroid hormone preparations - they need to learn that it doesn't depend on what the meaning of the word "is" is.
