:Levothyroxine sodium
Description:
Levothyroxine sodium, with the CAS number 55-03-8, is a synthetic form of the thyroid hormone thyroxine (T4) used primarily in the treatment of hypothyroidism. It is a white to off-white crystalline powder that is soluble in water and has a molecular formula of C15H11I4NNaO4. The substance acts by increasing the metabolic rate of tissues, influencing protein synthesis, and regulating the metabolism of carbohydrates and fats. Levothyroxine sodium is typically administered orally and is characterized by its high bioavailability and long half-life, allowing for once-daily dosing in most cases. It is essential for maintaining normal growth and development, particularly in children, and plays a critical role in energy metabolism. The drug's potency can be affected by various factors, including the presence of food, other medications, and individual patient characteristics. As with any medication, monitoring of thyroid hormone levels is crucial to ensure therapeutic effectiveness and to avoid potential side effects associated with over- or under-treatment.

Applications 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.
