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 achiral 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(D-thyroxine) was used in the past as a treatment for hypercholesterolemia (elevated cholesterol levels) but was withdrawn due to cardiac side effects.It is on the World Health Organization's List of Essential Medicines,a list of the most important medication needed in a basic health system
Levothyroxine (T4) is a synthetically prepared levo isomer of thyroxine, the major hormone secreted from the thyroid gland. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form triiodothyronine (T3) which exerts a broad spectrum of stimulatory effects on cell metabolism.
Thyroid hormone increases the metabolic rate of cells of all tissues in the body. In the fetus and newborn, thyroid hormone is important for the growth and development of all tissues including bones and the brain.
In adults, thyroid hormone helps to maintain brain function, food metabolism, and body temperature, among other effects. The symptoms of thyroid deficiency relieved by levothyroxine include slow speech, lack of energy, weight gain, hair loss, dry thick skin and unusual sensitivity to cold.
