Propylthioxypyrimethamine (PTU) and methionine (Tapazol), ATDs reduce thyroxine synthesis and are collectively known as antithyroid drugs (ATDs). They usually reduce thyroxine levels to within the normal range within 4 to 6 weeks and also inhibit the function of cells that produce anti-self thyroid antibodies that cause Graves’ disease. About 20% to 40% of patients with Graves’ disease can return their thyroid function to normal after 6 to 18 months of taking any of these drugs. For those with a thyroid weight of 40 grams or less, about 30% of patients can achieve a relatively long remission after 1.5-3 years of systematic, regular ATD treatment. Rash is the most common complication of ATD; rarely, it causes moderate to severe leukopenia or granulocytopenia, and sometimes liver and kidney damage and peripheral vasculitis. PTU is safer than Tapazol for pregnant patients. So far, the classical and effective treatment methods for hyperthyroidism are ATD, 131 iodine and surgery. I hope patients will be more careful with these beautiful words. When you go to a proper hospital and encounter so-called “well-wishers” and self-proclaimed “patients who have suffered from hyperthyroidism” who introduce or take you to a clinic or hospital to find a so-called director or specialist, you should be more alert to such “well-wishers”. These “nice people” may be the so-called medical trustees!
