Tiratricol
Tiratricol (also known as TRIAC or triiodothyroacetic acid) is a thyroid hormone analogue. It is indicated in the management of thyroid hormone resistance syndrome and is used, in combination with levothyroxine, to suppress thyroid-stimulating hormone production in patients with thyroid cancer. It has been investigated for use in reducing goiter. It has also shown some effectiveness in reducing the atrophy caused when using corticosteroids. Tiratricol has also been widely marketed, under various trade names, as a weight loss aid. In 1999 and 2000, the United States Food and Drug Administration and Health Canada both issued warnings to the public regarding the use of dietary supplements containing tiratricol. Tiratricol is not approved for sale in Canada or the United States. It was once an approved drug in Brazil, but its marketing authorization was suspended in 2003, effectively prohibiting its sale.

Tiratricol is a naturally occurring metabolite of T4 (thyroxine) and a structural analog of T3 (triiodothyronine). Low concentrations of tiratricol are found in plasma, but tiratricol has no known role in thyroid physiology. Tiratricol has a high affinity for T3 receptors and suppresses thyroid stimulating hormone (TSH) secretion at therapeutic doses without causing significant peripheral effects, such as increased basal metabolism rate and heart rate. Tiratricol might lower total and LDL cholesterol, and stimulate bone formation. About 67% of an oral dose of tiratricol is absorbed; the half-life is 6 hours. (L2139) Serum sex hormone-binding globulin levels increased 55 +/- 13% with tiratricol, indicating an augmented hepatic response to tiratricol. Tiratricol had effected the cardiovascular function. Tiratricol has distinct augmented hepatic and skeletal thyromimetic actions of potential therapeutic value. (A15458)

Orally, tiratricol can cause severe diarrhea, fatigue, lethargy, and profound weight loss. Heart attacks and strokes are possible, as well as symptoms of hyperthyroidism, including increased appetite, abdominal cramps, tremors, menstrual irregularities, nervousness, insomnia, sweating, intolerance to heat, fever, palpitations, tachycardia, increased pulse and blood pressure, chest pain, and cardiac arrhythmias. Case reports have implicated tiratricol in centrally-mediated hypothyroidism, pseudohypothyroidism, internuclear ophthalmoplegia, and hepatotoxicity. (L2139) It has been investigated for use in reducing goiter. It has also shown some effectiveness in reducing the atrophy caused when using corticosteroids. (Wikipedia) Tiratricol has been used to suppress pituitary TSH secretion, with reported attenuation of extrapituitary thyromimetic effects. (A15459)
