L-thyroxine (syn. Levothyroxine, T4) is a synthetically produced thyroid hormone. It replaces the thyroxine (T4) present in the human body, which is a precursor of the second thyroid hormone triiodothyronine (T3). The thyroid hormones are important for the development and function of the entire organism. They are mainly needed for the maturation of the brain. … L-Thyroxine
Dosage L-thyroxine fulfils the same functions as the body’s own thyroid hormones. Consequently, L-thyroxine is used when the thyroid gland no longer produces enough hormones on its own. The amount of hormones that is not produced enough must therefore be replaced by the corresponding amount of L-thyroxine. For this reason, the dosage of L-thyroxine must … Dosage | L-Thyroxine
Contraindications L-thyroxine must not be used if the thyroid gland is overactive. In addition, the drug should not be taken if the following diseases cannot be excluded: When treating post-menopausal women who have an increased risk of osteoporosis and suffer from hypothyroidism, the thyroid gland should be checked regularly to prevent elevated levels of L-thyroxine … Contraindications | L-Thyroxine
Is L-Thyroxine available over the counter? Since L-thyroxine has a major impact on the heart, metabolism and circulation, L-thyroxine is not available over the counter. The correct dosage is very important to avoid serious side effects. This can only be determined by a doctor by means of a blood sample and has to be controlled … Is L-Thyroxine available over the counter? | L-Thyroxine
Introduction Thyroxine, or “T4”, is a hormone produced in the thyroid gland. Thyroid hormones have a very broad spectrum of activity and are of great importance, especially for energy metabolism, growth and maturation. Since thyroid hormones, and thus also thyroxine, are subject to a superordinate and very complex control circuit and depend on the presence … Thyroxine
Tasks/function of thyroxine Hormones are the so-called “messenger substances of the body”. They are transported with the blood and pass on their information to the cells at their destination via a variety of different routes. Thyroid hormones even transmit their signals directly to the DNA. They bind directly to it and promote the reading of … Tasks/function of thyroxine | Thyroxine
Thyroxine Synthesis The synthesis of thyroxine takes place in the thyroid gland. The thyroid gland absorbs iodine from the blood and transfers it to the so-called “thyroglobulin”. Thyreroglobulin is a chain-like protein found in the thyroid gland, which is the basis for the synthesis of thyroid hormones. When iodine is transferred, molecules with either three … Thyroxine Synthesis | Thyroxine
