Levothyroxine synthesis

Synthesis of levothyroxine sodium, the sodium salt of a synthetic levoisomer of thyroxine, revolutionized the management of hypothyroidism and related

Levothyroxine's delayed onset of toxicity is thought to be secondary synthesis. Thyroid hormone is integral to the regulation of

Levothyroxine as shown in Scheme 1. Later development of levothyroxine synthesis involves iodination of 3,5-diodothyronine 3 and coupling between 3,5-diiodo L-tyrosine copper complex and bis(p-anisyl)iodonium iodide 4. Levothyroxine synthesis development is well documented as reviewed by Reddy et al.5. There was continuous improvement in

Ingestion of levothyroxine decreases the synthesis of endogenous T4, which has a long elimination half-life of about 6 7 days. Thus, the feedback inhibition of T4 synthesis by exogenous levothyroxine will not affect significantly (less than 4%) the plasma concentration of T4.
