Type:
Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4).
Mechanism of Action:
L-Thyroxine acts as a replacement for the natural thyroid hormone.
In the body, it is converted to L-Triiodothyronine (T3), the more active form of thyroid hormone.
This conversion mimics the natural process in the thyroid gland.
Uses:
It is primarily used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones.
It's also used in the treatment of goiter (thyroid enlargement) and in certain cases of thyroid cancer.
Administration:
It's typically taken orally, and dosage is adjusted based on regular blood tests to measure thyroid hormone levels.
