What is the mechanism of action of commonly used antithyroid drugs

The mechanism of action of commonly used antithyroid drugs is to inhibit thyroid peroxidase and block thyroid hormone synthesis. For patients with thyroid nodules, when taking antithyroid drugs, it can play an immunosuppressive role. Patients need reasonable iodine intake during medication, strictly follow the doctor's advice, carry out daily work and rest, do not stay up late, smoke; and do not use mobile phones for a long time. Maintain a calm state of mind to prevent emotional excitement and sadness, affecting thyroid hormone levels.
