Question

Short answer

Answer: A. Propylthiouracil (PTU)

Step-by-step solution

Understanding Hyperthyroidism

Hyperthyroidism is a condition where the thyroid gland produces excessive amounts of thyroid hormones, which can lead to symptoms such as weight loss, rapid heartbeat, and nervousness. The goal of treating hyperthyroidism is to bring the thyroid hormone levels back to normal.

Medication A: Propylthiouracil (PTU)

Propylthiouracil (PTU) is an antithyroid medication that works by inhibiting the production of thyroid hormones, consequently, it helps to normalize the excessive secretion of thyroid hormones.

Medication B: Fludrocortisone (Florinef)

Fludrocortisone (Florinef) is a corticosteroid used to treat conditions like Addison's disease and adrenogenital syndrome. It helps in regulating the balance of water and salts in the body. It does not directly influence or normalize thyroid hormone production in the body.

Medication C: Levothyroxine (Synthyroid)

Levothyroxine (Synthyroid) is a synthetic form of the thyroid hormone thyroxine (T4). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. It is mainly used to treat hypothyroidism (an underactive thyroid) rather than hyperthyroidism.

Medication D: Glipizide (Glucotrol)

Glipizide (Glucotrol) is an oral diabetes medication that helps control blood sugar levels by regulating the release of insulin from the pancreas. It does not directly influence thyroid hormone production.

Choosing the Correct Medication for Hyperthyroidism

From the given options, the medication that is specifically designed to treat hyperthyroidism by inhibiting thyroid hormone production is Propylthiouracil (PTU). Other medications do not directly target the excessive production of thyroid hormones. Therefore, the correct answer is: A. Propylthiouracil (PTU)
