TERTROXIN- Product Information Page 1 of 6 PRODUCT INFORMATION TERTROXIN NAME OF THE MEDICINE TERTROXIN Liothyronine sodium 20 microgram tablet C 15 H 11 I 3 NNaO 4 MW 673 CAS 55-06-1 DESCRIPTION Liothyronine (L triiodothyronine) sodium is a naturally occurring thyroid hormone. It is the sodium salt of the L- isomer of 3,3’,5 triiodothyronine. It is a white or slightly coloured powder, practically insoluble in water and slightly soluble in alcohol. Excipients: The other ingredients in TERTROXIN tablets are acacia, magnesium stearate, starch-maize, sodium chloride, lactose PHARMACOLOGY: The principal pharmacological effect of exogenous thyroid hormones is to increase the metabolic rate of body tissues. The biological action of liothyronine sodium is qualitatively similar to that of thyroxine but the effect develops in a few hours and disappears within 24-48 hours of stopping treatment. PHARMACOKINETICS: Liothyronine is readily and almost completely absorbed from the gastrointestinal tract following oral administration. In the circulation, liothyronine is principally bound to thyroxine-binding globulin (TBG). The plasma half-life of liothyronine in euthyroidism is approximately 1-2 days; it is prolonged in hypothyroidism and reduced in hyperthyroidism. Liothyronine should not be used in the management of obesity in euthyroid patients because doses within the range of daily hormonal requirements are ineffective and larger doses may produce serious or life threatening adverse effects.
