WebPropylthiouracil (PTU) is an antithyroid drug with a mechanism of action similar to methimazole (Tapazol). The most common cause of hypothyroidism is Graves’ disease. It is an autoimmune disease in which … WebTHIOAMIDES : Inhibit hormone synthesis by inhibiting peroxidase. Propylthiouracil also inhibits peripheral de-iodination of T4 and T3. Methimazole is more potent and longer acting than propylthiouracil. Slow in onset ~ 4 weeks. Thiocarbamide group – essential for anti thyroid activity 9.
