Possible Interaction: Iodine and Potassium Iodide

“ Potassium iodide (KI) can effectively block radioactive iodine from being absorbed by the thyroid gland if taken immediately after a radiation release.”

“Uptake of radioactive iodine by the thyroid was blocked by the administration of potassium iodide , 50 mg daily for two weeks.”

“In 2 control children prolonged administration of potassium iodide and TSH induced a defect of organic binding of iodine similar to that seen in iodide goiter.”

“He found that certain solutions of potassium iodide were capable of dissolving more iodine (Lugol's solution) which he felt "augmented the potency of the remedy."”

“Analogues 8a,b and 13a were less potent than CPX, but for each the Ki of antagonism was > or = 0.5 nM. Attempts to iodinate the 8-(4-hydroxyphenyl) analogue of CPX failed, probably because the xanthine substituent strongly deactivated the phenol toward electrophilic iodination.”

“A decided increase in the concentration of iodine in the saliva has been observed in man after oral administration of potassium iodide.”

“The potassium iodide concentration influences the iodine content of supernatant and pellet, but not hydrolysis.”

“Both decreasing the free iodine level through addition of potassium iodide and increasing the free iodine level through dilution of the product resulted in an increased length of survival of P. aeruginosa in contaminated PxI solution.”

“Polyvinyl acetate and iodine form a characteristic red complex in the presence of potassium iodide.”

“In the presence of an iodide salt like potasium iodide the solubility of free iodine may be increased several hundredfold, the increase being in the form of triiodide according to the equation: (1) Ta+ 1 Ir.”
