Thiamazole is an imidazole antithyroid drug whose chemical composition is methimazole, which is a round film-coated piece with a score. Its mechanism of action is to inhibit peroxidase in the thyroid gland, thereby hindering the absorption of iodide in the thyroid gland and the coupling of tyrosine, which hinders the synthesis of thyroxine (T4) and triiodothyronine (T3). Animal experiments have observed that it can inhibit the synthesis of antibodies by B lymphocytes, reduce the level of thyroid stimulating antibodies in the blood circulation, and restore the function of suppressor T cells.

Function:
1. Medical treatment of hyperthyroidism
It is suitable for those who are mild and unsuitable for surgery or radioactive iodine treatment, such as children, adolescents and patients who relapse after surgery and are not suitable for radioactive iodine treatment. It can also be used as an adjuvant treatment in the treatment of radioactive iodine.
2. Treatment of thyroid crisis
In addition to the use of large doses of iodine and other comprehensive measures, a large number of this product can be used as an adjuvant treatment to block the synthesis of thyroxine.
