[edit] Wrong picture

The picture is definitely wrong. Levothyroxine is derived from the amino acid tyrosine. The nitrogen should be a(n) (alpha) carbon instead, and should have an amino group attached the alpha carbon.

[edit] Flip it around

I think that you are looking at the molecule backwards. If you invert it, it looks the same in my opinion. But the only difference that I see is that the carboxylic group is ionized and there is a non-ionic bond with a sodium molecule.

[edit] Corrected

I believe whatever factual errors there were in this article have been corrected.The molecule is shown in the non-ionized state and there is no sodium atom present.

Here is a more complete and easier to understand page. http://en.wikipedia.org/wiki/Levothyroxine

[edit] Marketing and Approval

The report referred to "various complaints" during the 1990s which led to the FDA reviewing Synthroid, and it needed citation. The only citation I could find was WorstPills.org, which cited scientific studies concerned about Synthroid's effectiveness versus the effectiveness of other levothyroxines. I am not entirely convinced of "WorstPills"'s impartiality, but it was the only resource I can find. If someone can find a better citation, it would be much appreciated. 70.187.186.35 08:57, 23 July 2007 (UTC)
