Т4, также известный как L-тироксин и левотироксин , синтетический гормон щитовидной железы, химически идентичный тироксину (Т4), который естественным образом секретируется фолликулярными клетками щитовидной железы.. Используется для лечения дефицита гормонов щитовидной железы., и иногда для предотвращения рецидива рака щитовидной железы. Как и его естественно секретируемый аналог, levothyroxine is a chiral compound in the L-form.
T4 is a replacement for a hormone normally produced by your thyroid gland to regulate the body’s energy and metabolism. Levothyroxine is given when the thyroid does not produce enough of this hormone on its own.
T4 treats hypothyroidism (low thyroid hormone). It is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer.
T4 is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured byradiation/medications or removed by surgery. Having enough thyroid hormone is important for maintaining normal mental and physical activity. In children, having enough thyroid hormone is important for normal mental and physical development.
This medication is also used to treat other types of thyroid disorders (such as certain types of goiters, thyroid cancer).
One of the thyroid hormones involved in the maintenance of metabolic homeostasis. Синтезируется и хранится в виде аминокислотных остатков тиреоглобулина., основной белковый компонент фолликулярного коллоида щитовидной железы. Synthesis and secretion are regulated by the people.
This medication should not be used to treat infertility unless it is caused by low thyroid hormone levels.
