Thyro3 (Generic Liothyronine Sodium 25mcg tablets) is a
synthetic form of triiodothyronine (T3), a thyroid hormone used
to treat coma of myxedema, the management of severe chronic
thyroid deficiency and hypothyroidism, a condition wherein the
thyroid gland does not produce enough thyroid hormone. It is
also used to help decrease the size of enlarged thyroid glands
(goiter) and treat thyroid cancer.
Liothyronine is also used in some medical tests to help diagnose
problems with the thyroid gland.
T3 is the metabolically active thyroid hormone, which causes
feedback inhibition, and lowers elevated TSH levels. It increases
metabolism in peripheral tissues and is indicated when there is
an impaired conversion of T4 to T3 in peripheral tissues.
