What is Liothyronine?
Liothyronine is the biologically active form of thyroid hormone. While the thyroid gland secretes most hormones as thyroxine (T4), a small proportion is released directly as T3, which exerts metabolic effects immediately. In peripheral tissues, T4 is converted to T3 by selenium‑dependent enzymes called monodeiodinases.
Clinical Uses
- Treatment of hypothyroidism when levothyroxine alone is insufficient.
- Adjunct therapy in thyroid hormone replacement protocols.
- Short‑term management of thyrotoxic crisis or severe hyperthyroidism.
