Final answer:
PTU and methimazole are drugs used to treat hyperthyroidism by inhibiting thyroid hormone synthesis, while beta blockers manage symptoms and steroids are used in certain thyroid conditions.
Step-by-step explanation:
The drugs used to treat hyperthyroidism include PTU (Propylthiouracil) and methimazole, which are antithyroid medications. These drugs work by impeding the synthesis of thyroid hormones (T3 and T4) that control the basal metabolic rate. Specifically, PTU and methimazole inhibit the enzyme thyroperoxidase, which is necessary for the production of thyroid hormones. Beta blockers are also used in the management of hyperthyroidism; however, they do not directly affect thyroid hormone production, but rather control the symptoms by reducing the effects of increased levels of these hormones on the heart. Steroids are not a primary treatment for hyperthyroidism but may be used in certain inflammatory conditions of the thyroid gland, such as subacute thyroiditis.
