Putting together a T-3 Manual...Here...

[BigAndy69]

are some interesting tidbits from Medscape:

********************* Approximate Equivalent Dosage
Levothyroxine Sodium(T4) 100 µg or less
Liothyronine Sodium(T3) 25 µg
Liotrix Levothyroxine Sodium/Liothyronine Sodium 50 µg/12.5 µ
Thyroglobulin 65 mg
Thyroid 60—65 mg (1 grain)


Liothyronine sodium(This is T3) is almost completely absorbed from the GI tract (about 95%) following oral administration. Because triiodothyronine is not highly or firmly protein bound, liothyronine has a more rapid onset of pharmacologic action and a shorter duration of action than levothyroxine(T4 seems to be crap). The usual plasma half-lives of triiodothyronine and thyroxine are approximately 1—2 days and 6—7 days, respectively. The plasma half-lives of thyroxine and triiodothyronine are decreased in patients with hyperthyroidism and increased in those with hypothyroidism.

THIS ONE I DIDN"T KNOW:

Certain medicines may decrease absorption of this drug into your bloodstream. Therefore, take this 4 hours apart from: calcium or iron supplements; aluminum or calcium antacids; cholestyramine or colestipol; sucralfate or sodium polystyrene sulfonate.

In regard to your last comment about T-3 and interactions with other substances. Most physicians will suggest taking your entire daily dose first thing in the AM on an empty stomach. I do not feel most physicians took into account the mcg dosage most bb ingest, 100mcg first thing in the morning, I would be out of my mind by 7AM and sweating like a mofo. PEACE

Antacids interfere with the absorption of many oral drugs such as antibiotics. It does not seem to be a good idea to take these along with any oral.
