L-Thyroxine Sodium, commonly referred to as Levothyroxine Sodium or LT4 Sodium, is a synthetic form of the thyroid hormone thyroxine (T4). It is primarily used in the treatment of hypothyroidism — a condition where the thyroid gland does not produce enough thyroid hormones. This medication plays a crucial role in managing various hormonal imbalances and maintaining metabolic functions within the body.
