What is Levothyroxine

The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (monoiodotyrosine) and the coupling of iodotyrosines (diiodotyrosine) in the thyroglobulin. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form triiodothyronine which exerts a broad spectrum of stimulatory effects on cell metabolism.

Levothyroxine mechanism of action

Levothyroxine acts like the endogenous thyroid hormone thyroxine (T sub4 /sub, a tetra-iodinated tyrosine derivative). In the liver and kidney, T sub4 /sub is converted to T sub3 /sub, the active metabolite. In order to increase solubility, the thyroid hormones attach to thyroid hormone binding proteins, thyroxin-binding globulin, and thyroxin-binding prealbumin (transthyretin). Transport and binding to thyroid hormone receptors in the cytoplasm and nucleus then takes place. Thus by acting as a replacement for natural thyroxine, symptoms of thyroxine deficiency are relieved.

What is a Synthroid?

Synthroid is a medicine for the thyroid gland that replaces a hormone, usually produced by your thyroid gland, to regulate the body’s energy and metabolism. Levothyroxine is prescribed when the thyroid gland does not produce enough of this hormone on its own. Synthroid treats hypothyroidism (low thyroid hormone).

Synthroid is also used to treat or prevent goiter (an enlarged thyroid gland), which can be caused by hormonal imbalances, radiation therapy, surgery, or cancer.

You may not be able to take synthroid if you have certain medical conditions. Tell your doctor if you have an untreated or uncontrolled adrenal disorder, a thyroid disorder called thyrotoxicosis, or if you have recent or current symptoms of a heart attack.

Synthroid should not be used to treat obesity or weight problems. Dangerous side effects or death may occur due to improper use of levothyroxine, especially if you are taking any other medications for weight loss or appetite suppression.
