Levothyroxine Sodium API is the sodium salt of levothyroxine, the synthetic levoisomer of thyroxine (T4), a naturally occurring thyroid hormone. It is a highly potent thyroid hormone pharmaceutical ingredient used as thyroid hormone replacement therapy, particularly in the management of hypothyroidism. Levothyroxine is converted in peripheral tissues to the more biologically active thyroid hormone triiodothyronine (T3), which participates in the regulation of cellular metabolism, growth, development and thermogenesis.
Chemically, Levothyroxine Sodium is the sodium salt of L-thyroxine and contains four iodine atoms within its molecular structure. The anhydrous sodium salt has the molecular formula C₁₅H₁₀I₄NNaO₄, molecular weight approximately 798.85 g/mol, and CAS number 55-03-8.
Levothyroxine Sodium is an iodinated amino-acid derivative and is structurally related to endogenous thyroid hormone T4. Because of its very high potency and the importance of precise dose delivery, control of identity, potency, related substances, water/hydration state and other critical quality attributes is particularly important during pharmaceutical manufacturing and quality control.
The exact solid form is important for specification purposes. PubChem separately identifies Levothyroxine Sodium anhydrous, Levothyroxine Sodium monohydrate, and other hydrated forms. For example, the monohydrate is listed with molecular formula C₁₅H₁₂I₄NNaO₅ and molecular weight 816.87 g/mol.
