PTU, or Propylthiouracil, is a medication used to manage hyperthyroidism by inhibiting the production of thyroid hormones. It works by blocking the enzyme thyroperoxidase, which is essential for the synthesis of thyroxine (T4) and triiodothyronine (T3) in the thyroid gland. This reduction in hormone levels helps alleviate symptoms of hyperthyroidism, such as rapid heartbeat and weight loss. PTU is often prescribed for conditions like Graves' disease and is particularly useful in patients who cannot tolerate other treatments.
