L-Thyroxine Sodium Hydrate (CAS: 25416-65-3) is a useful research chemical. Its free form Thyroxine (T425600) is one of the thyroid hormones involved in the maintenance of metabolic homeostasis. Synthesized and stored as amino acid residues of thyroglobulin, the major protein component of the thyroid follicular colloid. Synthesis and secretion are regulated by the pituitary hormone (TSH). Deiodinated in peripheral tissues to the active metabolite, liothyronine. The D-form has very little activity as a thyroid hormone, but has been used to treat hyperlipidemia. Levothyroxine is typically used to treat hypothyroidism,and is the treatment of choice for patients with hypothyroidism, who often require lifelong thyroid hormone therapy.It may also be used to treat goiter via its ability to lower thyroid-stimulating hormone (TSH), a hormone that is considered goiter-inducing. Levothyroxine is also used as interventional therapy in patients with nodular thyroid disease or thyroid cancer to suppress thyroid-stimulating hormone (TSH) secretion.
