Pharmacology
IndicationPotassium Iodide is oral antithyroid agent. Potassium Iodide is used as an adjunct to other antithyroid agents in the treatment of hyperthyroidism and thyrotoxicosis and preoperatively to induce thyroid involution.
Structured Indications
PharmacodynamicsIt works in the thyroid gland. By inhibiting thyroid hormone synthesis and release, thyroid gland vascularity is reduced, thyroid gland tissue becomes firmer, thyroid cell size is reduced, follicular colloid reaccumulates, and bound iodine levels increase. As a protectant following radiation exposure, KI blocks the uptake of radioactive iodine isotopes by the thyroid gland thereby minimizing the risk of radiation-induced thyroid neoplasms.
