Application:
L-Thyroxine Sodium Salt Pentahydrate (CAS: 6106-07-6) is a synthetic hormone for the research of hypothyroidism. Thyroid Hormone Receptor. L-Thyroxine Sodium Salt Pentahydrate is a synthetic thyroid hormonethat is chemically identical to thyroxine (T4), which is naturally secreted by the follicular cells of the thyroid gland. It is used to treatthyroid 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(D-thyroxine) was used in the past as a treatment for hypercholesterolemia (elevated cholesterol levels) but was withdrawn due to cardiac side effects. Levothyroxine 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 by radiation/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 thyroid cancer). It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.Sufficient Capacity: Sufficient facilities and technicians
