What are the chemical reactions involved in the body after taking Eltroxin tablet?
How does it work? Eltroxin tablets contain the active ingredient levothyroxine sodium (previously known simply as thyroxine sodium in the UK). (NB. Levothyroxine is also available without a brand name, ie as the generic medicine.) Levothyroxine is the same as the hormone thyroxine, which is produced naturally by the thyroid gland. The thyroid gland produces and releases two thyroid hormones: thyroxine (T4) and tri-iodothyronine (T3). Tri-iodothyronine is the more active thyroid hormone, and thyroxine is converted into T3 in various parts of the body. These hormones are responsible for maintaining a normal rate of metabolism in the body. When the thyroid gland is unable to produce normal amounts of thyroxine, the level of both thyroid hormones in the blood decreases (hypothyroidism). This results in a reduced rate of metabolism, leading to symptoms such as weight gain, intolerance to cold and tiredness. Levothyroxine tablets are given to replace the thyroxine that would normally be prod
