Thyroid Hormone

Thyroid Hormone Function

The thyroid gland is responsible for producing and regulating the thyroid hormone, which plays a crucial role in metabolism and growth. Thyroid hormones consist of two main forms, T3 (triiodothyronine) and T4 (thyroxine), which are released into the bloodstream and transported throughout the body to control various functions.

What Is Levothyroxine Sodium Used To Treat?

Levothyroxine sodium is a synthetic form of T4 and is commonly used as a replacement therapy for individuals with an underactive thyroid gland (hypothyroidism). It works by supplementing the missing thyroid hormone and restoring normal metabolic functions. Levothyroxine sodium is also used to treat goiters, a condition where the thyroid gland becomes enlarged.

What Is The Treatment For Hypothyroidism?

Liothyronine sodium, on the other hand, is a synthetic form of T3 and is sometimes used in combination with levothyroxine sodium to treat hypothyroidism. However, it is primarily used to diagnose and treat hyperthyroidism, a condition where the thyroid gland produces too much thyroid hormone.
