What does it do?

Liothyronine sodium is the sodium salt form of the active thyroid hormone T3 (triiodothyronine) secreted by the thyroid gland. It helps regulate metabolism by supplementing thyroid hormones in patients with hypothyroidism. It primarily belongs to the class of thyroid hormone preparations.

Liothyronine sodium acts as the thyroid hormone T3 in the body, promoting metabolic activities within cells. This normalizes various physiological functions including energy production, temperature regulation, and cardiac function. It helps alleviate symptoms related to hypothyroidism.

Good to know

Liothyronine sodium is characterized by directly providing the active hormone T3, rather than T4 (thyroxine). Therefore, rapid effects can be expected during treatment for hypothyroidism; however, it may be difficult to regulate. This distinguishes it from T4 preparations.
