Final answer:
Antithyroid drugs, used to treat hyperthyroidism, inhibit thyroid hormone release by blocking the synthesis of these hormones and reducing iodine uptake by the thyroid gland.
Step-by-step explanation:
The true statement about antithyroid drugs is that they inhibit thyroid hormone release. These drugs are primarily used to treat hyperthyroidism, such as in Graves' disease, by reducing the production and release of thyroid hormones. Specifically, certain drugs like thiourea and thiouracil work by inhibiting the enzyme thyroperoxidase, which is necessary for the synthesis of thyroid hormones. Additionally, compounds such as thiocyanate, perchlorate, and ouabain inhibit iodine uptake by the thyroid gland, which is also crucial for hormone production. Therefore, antithyroid drugs can be effective in controlling hyperthyroidism. It's also worth noting that while long-term treatment can lead to remission in some patients, it is not guaranteed, and careful management is required to monitor thyroid function and the potential side effects on development, including fetal development when applicable.
