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cholesterol levels) but was withdrawn due to cardiac side effects. 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 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.

L-Thyroxine Dosage:

Levothyroxine is taken on an empty stomach approximately half an hour to an hour before meals. As such, thyroid replacement therapy is usually taken 30 minutes prior to eating in the morning. For patients with trouble taking levothyroxine in the morning, bedtime dosing is effective as well. A recent study published in JAMA showed greater efficacy of levothyroxine when taken at bedtime.

Thyroxine (T4)
The thyroid hormone, thyroxine (T4) is a tyrosine-based hormone which is produced by the thyroid gland. Synthetic versions of this hormone are used to make up for a lack of naturally produced thyroxine and increase the rate of metabolism. Artificially made thyroid hormone improves the symptoms of hypothyroidism (underactive thyroid) and speeds the rate of metabolism in those who suffer from the disease. Thyroid hormones may also be used to treat goiter (enlarged thyroid gland) and certain types of thyroid cancer.

T4 thyroid hormone is levothyroxine which is sold under the brand names: Synthroid, Levoxyl, and Levothroid.

Action
Thyroid hormone controls the rate of metabolism. When the thyroid is under active, all body processes slow down and symptoms such as weight gain, fatigue, and decreased body temperature are experienced. Through supplementation of thyroid hormones, basal metabolic rate will be increased.

Thyroid hormones are essential to proper development of all cells in body. These hormones allow for the body to become more sensitive to all other hormones, in turn making them more effective. Thyroid hormones also regulate macronutrient (protein, fat and carbohydrate) metabolism, therefore increasing protein synthesis and ultimately energy. This allows for the body to burn more calories and use them more sufficiently. For this reason, thyroid hormones are commonly used as fat-loss drugs.

This medicine does not typically cause side effects as long as proper dosages are administered. However some drawbacks of Thyroid drug use are cardiac stress and possible loss of lean body mass. Negative feedback in the thyroid can decrease natural production of thyroid hormone, causing short term decrease of metabolic rate after use is discontinued.

Technical Data

Many studies have proven that while calories and carbohydrates are restricted, levels of diodinase, the enzyme that activates thyroid hormone production, decreased. The conversion of T4 into T3, the active form of thyroid hormone, was became hindered (1). Users discovered T3 to be a better choice over T4 when using Thyroid drugs during Cyclic Ketogenic Diets.

T4 must be used in much higher doses to be as effective as T3. Subjects found they needed to use a dosage of 300 mcg/day to achieve the same results as 25-100 mcg/day of T3 (Cytomel).
