Drug Names(s): levothyroxine, T4, Elthyrone
Description: Synthroid is a synthetic molecule that is identical to the T4 (L-thyroxine) thyroid hormone produced by the thyroid gland. The mechanisms by which thyroid hormones exert their physiologic actions are not completely understood, but it is thoughtthat their principal effects are exerted through control of DNA transcription and protein synthesis.
T4 diffuses into the cell nucleus and binds to thyroid receptor proteins attached to DNA. This hormone nuclear receptor complex activates genetranscription and synthesis of messenger RNA and cytoplasmic proteins. Thyroid hormones regulate multiple metabolic processes and play an essential role in normal growth and development, and normal maturation of the central nervous system and bone. The metabolic actions of thyroid hormones include augmentationof cellular respiration and thermogenesis, as well as metabolism of proteins, carbohydrates and lipids.
