2. Desiccated thyroid extract - Wikipedia

   en.wikipedia.org/wiki/Desiccated_thyroid_extract

   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 ...

3. Equianalgesic - Wikipedia

   en.wikipedia.org/wiki/Equianalgesic

   An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...

4. 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 ...

   Levothyroxine, a drug used to treat hypothyroidism, can lead to reduced bone mass and density in older adults with normal thyroid levels, a small cohort study has shown.

6. Liothyronine - Wikipedia

   en.wikipedia.org/wiki/Liothyronine

   Liothyronine may be used when there is an impaired conversion of T 4 to T 3 in peripheral tissues. [2] The dose of liothyronine for hypothyroidism is a lower amount than levothyroxine due it being a higher concentrated synthetic medication. [2] About 25 μg of liothyronine is equivalent to 100 μg of levothyroxine. [3]

7. Iodothyronine deiodinase - Wikipedia

   en.wikipedia.org/wiki/Iodothyronine_deiodinase

   Like during fetal development, thyroid hormone levels are low in the overloaded heart tissue in a local hypothyroid state, with low levels of deiodinase 1 and deiodinase 2. Although deiodinase 3 levels in a normal heart are generally low, in cardiomyopathy deiodinase 3 activity is increased to decrease energy turnover and oxygen consumption. [7]

8. Thyroid - Wikipedia

   en.wikipedia.org/wiki/Thyroid

   The thyroid gland is a butterfly-shaped organ composed of two lobes, left and right, connected by a narrow tissue band, called an "isthmus". [4] It weighs 25 grams in adults, with each lobe being about 5 cm long, 3 cm wide, and 2 cm thick and the isthmus about 1.25 cm in height and width. [4]
