Study Notes
Thioamide Drugs
- Methimazole and propylthiouracil (PTU) are thioamide drugs used to treat hyperthyroidism.
- They work by blocking the synthesis of thyroid hormones.
- PTU carries a black box warning due to a higher risk of liver toxicity (hepatotoxicity) compared to methimazole.
- Methimazole is contraindicated during the first trimester of pregnancy.
Potassium Iodide (Lugol's Solution)
- Used to suppress thyroid function before thyroid surgery.
- Also used to treat thyroid storm (severe hyperthyroidism).
Sodium Iodide (I-131)
- Radioactive iodine used to treat hyperthyroidism and thyroid cancer.
