Mechanism of Action
In general, potassium binders are artificial resins that exchange bound cations (Ca2+ or Na+) for potassium ions in the large intestine. After exchange, the released cation and potassium adhering to the resin are excreted with the faeces. This mechanism prevents intestinal absorption of alimentary potassium ions and thereby reduces serum potassium levels. There are two major classes of binders, differentiated by the cation attached to the resin in the original condition. Calcium resins release calcium ions in exchange for potassium ions, whereas sodium resins release sodium.

Famous quotes containing the words mechanism of, mechanism and/or action:
“The two elements the traveler first captures in the big city are extrahuman architecture and furious rhythm. Geometry and anguish. At first glance, the rhythm may be confused with gaiety, but when you look more closely at the mechanism of social life and the painful slavery of both men and machines, you see that it is nothing but a kind of typical, empty anguish that makes even crime and gangs forgivable means of escape.”
—Federico García Lorca (1898–1936)

“Not rarely, and this is especially true of wives and mothers, the motive behind assuming a disproportionate share of work and responsibility is completely unselfish. We want to protect, to spare those of whom we are fond. We forget that, regardless of the motive, the results of such action are almost always destructive and unproductive.”
—Hortense Odlum (1892–?)
