Final answer:
Anti-thyroid medications for hyperthyroidism include Methimazole (Tapazole) and Propylthiouracil (PTU), which inhibit thyroid hormone synthesis, whereas Levothyroxine, Liothyronine, and Liotrix are thyroid hormone replacements for hypothyroidism.
Step-by-step explanation:
The student is asking about anti-thyroid drugs used in the treatment of hyperthyroidism. Among the options provided, drugs B, Methimazole (Tapazole), and E, Propylthiouracil (PTU) are correct. These medications work by inhibiting the synthesis of thyroid hormones, as they are thiourea derivatives which inhibit the enzyme thyroperoxidase, necessary for hormone production. On the other hand, A, Levothyroxine, C, Liothyronine, and D, Liotrix are thyroid hormone replacements used in the treatment of hypothyroidism. These provide exogenous thyroid hormones to replace the deficient levels in patients with an underactive thyroid.
