Levothyroxine. Levothyroxine, also known as L-thyroxine, is a synthetic form of the thyroid hormone thyroxine (T 4 ). [ 5][ 8] It is used to treat thyroid hormone deficiency (hypothyroidism), including a severe form known as myxedema coma. [ 5] It may also be used to treat and prevent certain types of thyroid tumors. [ 5]
Hyperthyroidism is the condition that occurs due to excessive production of thyroid hormones by the thyroid gland. [ 3] Thyrotoxicosis is the condition that occurs due to excessive thyroid hormone of any cause and therefore includes hyperthyroidism. [ 3] Some, however, use the terms interchangeably. [ 5]
Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [ 1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control, dyshomeostatic disorders ...

Desiccated Thyroid became a commercial treatment option in 1934 with Westhroid, [citation needed]. In the early 1960s, desiccated thyroid hormones (thyroid extract) began to be replaced by levothyroxine (synthetic T4), or by combinations of T4 and T3. Replacement occurred faster in the United Kingdom than in North America, but by the 1980s more ...
The primary treatment of thyroid storm is with inorganic iodine and antithyroid drugs (propylthiouracil or methimazole) to reduce synthesis and release of thyroid hormone. Temperature control and intravenous fluids are also mainstays of management. Beta blockers are often used to reduce the effects of thyroid hormone. [5] Patients often require ...
It works by decreasing the amount of thyroid hormone produced by the thyroid gland and blocking the conversion of thyroxine (T4) to triiodothyronine (T3). [3] Propylthiouracil came into medical use in the 1940s. [5] It is on the World Health Organization's List of Essential Medicines. [6]
