2. Levothyroxine - Wikipedia

   en.wikipedia.org/wiki/Levothyroxine

   Levothyroxine is a synthetic form of thyroxine (T 4), which is secreted by the thyroid gland. Levothyroxine and thyroxine are chemically identical: natural thyroxine is also in the "levo" chiral form, the difference is only in terminological preference. T 4 is biosynthesized from tyrosine. Approximately 5% of the US population suffers from over ...

3. Thyroid hormones - Wikipedia

   en.wikipedia.org/wiki/Thyroid_hormones

   Thyroid hormones act on nearly every cell in the body. They act to increase the basal metabolic rate, affect protein synthesis, help regulate long bone growth (synergy with growth hormone) and neural maturation, and increase the body's sensitivity to catecholamines (such as adrenaline) by permissiveness.

   Levothyroxine should be used to keep TSH levels within the normal range for that trimester. The first-trimester normal range is below 2.5 mIU/L and the second and third trimesters normal range is below 3.0 mIU/L. [ 16 ] [ 44 ] Treatment should be guided by total (rather than free) thyroxine or by the free T 4 index .

6. Liothyronine - Wikipedia

   en.wikipedia.org/wiki/Liothyronine

   For patients taking levothyroxine, TSH may be boosted by discontinuing levothyroxine for 3–6 weeks. [6] This long period of hormone withdrawal is required because of levothyroxine's relatively long biological half-life, and may result in symptoms of hypothyroidism in the patient. The shorter half-life of liothyronine permits a withdrawal ...

   Long-term management of hyperthyroidism may include drugs that suppress thyroid function such as propylthiouracil, carbimazole and methimazole. [50] Alternatively, radioactive iodine-131 can be used to destroy thyroid tissue: radioactive iodine is selectively taken up by thyroid cells, which over time destroys them.
