DescriptionLiothyronine is a thyroidal hormone T3 which is normally produced by the thyroid gland in a ratio 4:1 when compared with T4: T3. Liothyronine is the active form of thyroxine which is composed in a basic chemical structure by a tyrosine with bound iodine.[T457] The exogenous liothyronine product was developed by King Pharmaceuticals and FDA approved in 1956.[L5578]

IndicationLiothyronine is officially approved for the following indications: - Replacement therapy in primary (thyroidal), secondary (pituitary) and tertiary (hypothalamic) congenital or acquired hypothyroidism. - As an adjunct therapy to surgery and radioiodine in the management of thyroid cancer. - As a diagnostic agent in suppression tests for mild hyperthyroidism or thyroid gland autonomy.[FDA label] In general terms, exogenous liothyronine is used to replace insufficient hormonal production and restore T3 plasma levels.[T457] The lack of liothyronine can be presented as a pale and puffy face, coarse, brittle hair, dry skin, croaky voice and constipation as well as irregular periods, drowsiness, and lethargy.[T457] Liothyronine should never be used in the suppression of benign nodules and nontoxic diffuse goiter in iodine-sufficient patients nor in the treatment of hyperthyroidism during the recovery phase of subacute thyroiditis.[FDA label]
