Hyperthyroidism (hyperthyroidism) is an autoimmune disease that can affect both men and women, but is more common in women, and has many complications, such as hyperthyroid heart disease, hyperthyroid proptosis, hyperthyroid anemia, hyperthyroidism with diabetes, and hyperthyroidism with myopathy. Since the 1940s, the basic treatment for Graves’ hyperthyroidism has been antithyroid drug therapy (ATD), radioactive iodine-131 therapy and subtotal thyroidectomy. ATD is used as a basic treatment for patients with mild disease, small thyroid gland and combined pregnancy, or as a preparatory drug before surgery. However, ATD has a long course, slow effect and high recurrence rate, and the possible side effects such as leukopenia, allergy and liver damage need to be observed regularly during the course of treatment. Therefore, ATD therapy is only given for a long time as a decisive treatment in patients who are frail, elderly or unwilling to undergo iodine-131 therapy or who are not suitable for surgical treatment in medical units that are equipped to carry out iodine-131 therapy and have more surgical experience. Commonly used antithyroid drugs include tapazole tablets (Tapazole) and propylthiouracil tablets (PTU).
