Description

Levothyroxine (INN, USAN) or L-thyroxine is a synthetic  thyroid hormone that is chemically identical to thyroxine (T4), which is  naturally secreted by the follicular cells of the thyroid gland. It is used to  treat thyroid hormone deficiency, and occasionally to prevent the recurrence of  thyroid cancer. Like its naturally secreted counterpart, levothyroxine is a  chiral compound in the L-form. The related drug dextrothyroxine (D-thyroxine)  was used in the past as a treatment for hypercholesterolemia (elevated  cholesterol levels) but was withdrawn due to cardiac side effects.

Application

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
