Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodine-131 is taken up by the thyroid gland and emits beta particles and gamma rays, causing destruction of thyroid tissue via radiation-induced cell death.
Inhibits hepatic glucose production by activating AMP-activated protein kinase (AMPK) and reduces intestinal glucose absorption; also improves insulin sensitivity.
For thyroid ablation: 3.7-5.55 MBq (100-150 μCi) orally as a single dose. For hyperthyroidism: 185-555 MBq (5-15 mCi) orally as a single dose.

Terminal half-life is approximately 120-140 days for total body iodine, but the effective half-life for therapeutic use is 8-13 days due to biological turnover in the thyroid. For diagnostic use, effective half-life is 1-2 days.
Terminal elimination half-life is 12-15 hours (mean 13.5 h); clinically significant for twice-daily dosing in hepatic impairment or drug interactions.
Primarily renal: >90% excreted in urine as iodide. Fecal excretion is negligible (<2%).
Primarily renal excretion of unchanged drug (60-70%); biliary excretion accounts for 20-25%; fecal elimination <10%.
