INS and Hypokalemia: GIK is a “cocktail” recipe that consists of dextrose, insulin, and potassium: insulin has a bioactive role in the anti-inflammatory, antioxidation, and antiapoptotic effects in various conditions; dextrose resists hypoglycemia; insulin and dextrose together assist the transfer of potassium from extracellular to intracellular fluids; and all three components work together to exert bioactive effects without the side effects of hypoglycemia and hypokalemia [29].
