Levothyroxine Sodium

Overview

Basic Info

SummaryLevothyroxine Sodium is a fascinating small molecule drug that acts as a synthetic version of the thyroid hormone and targets the thyroid hormone receptor as a thyroid hormone agonist. Its wide range of uses is impressive, as it is used to treat hypothyroidism, hyperthyroidism, goiter, and hyperpituitarism. Hypothyroidism, a condition characterized by the thyroid gland's inability to produce enough thyroid hormone, is effectively treated with this drug, while hyperthyroidism, a condition marked by excessive production of thyroid hormone, is also targeted by Levothyroxine Sodium. Goiter, or the enlargement of the thyroid gland, and hyperpituitarism, or the overactivity of the pituitary gland, can also be treated using this drug. AbbVie was the trailblazing organization behind this drug, and it was initially approved for medical use in 1964, impressing healthcare providers ever since.
