About Potassium Iodide

Mechanism of Action of Potassium Iodide
It 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.

Indications for Potassium Iodide
1.Potassium 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.
2.To protect the thyroid gland from radiation injury before and following administration of radioactive iodide (e.g., for diagnostic purposes) and in radiation emergencies (e.g., accidental exposure to radiation).
3.Chronic respiratory problems such as asthma, chronic bronchitis, and emphysema(expectorant).
4.Component of some eye drops.
5.Antifungal: Cutaneous Sporotrichosis is a fungus that can cause lesions on the skin. A saturated solution of potassium iodide can be used to treat the lesion.
