Liothyronine Sodium: Synthetic Triiodothyronine (T3)
Liothyronine sodium is the sodium salt of the synthetic L-isomer of triiodothyronine (T3), the most metabolically active thyroid hormone. It binds directly to nuclear thyroid hormone receptors, activating gene transcription involved in basal metabolic rate, thermogenesis, and protein synthesis. Liothyronine has a faster onset and shorter duration of action than levothyroxine (T4).

Applications
Liothyronine sodium is used for thyroid hormone replacement in hypothyroidism, either alone or in combination with levothyroxine. Intravenous liothyronine is used in the treatment of myxedema coma where rapid onset of action is critical. It is also used in the T3 suppression test for diagnostic evaluation of thyroid function. Oral tablets are available in strengths of 5, 25, and 50 mcg. Due to its short half-life (approximately 2.5 days), multiple daily doses are typically required for stable serum T3 levels.
