NCIt definition : A metal halide composed of potassium and iodide with thyroid protecting and expectorant
properties. Potassium iodide can block absorption of radioactive iodine by the thyroid
gland through flooding the thyroid with non-radioactive iodine and preventing intake
of radioactive molecules, thereby protecting the thyroid from cancer causing radiation.
In addition, this agent acts as an expectorant by increasing secretion of respiratory
fluids resulting in decreased mucus viscosity.;
