The pharmaceutical composition of claim 1 wherein the alpha-fluoroacrylic acid polymer is crosslinked with divinylbenzene, ethylene bisacrylamide, N,N'-bis(vinylsulfonylacetyl)ethylene diamine, 1,3-bis(vinylsulfonyl) 2-propanol, vinylsulfone, N,N'-methylenebisacrylamide polyvinyl ether, polyallylether, or a combination thereof.
5. The pharmaceutical composition of claim 1 wherein the alpha-fluoroacrylic acid polymer is crosslinked with divinyl benzene.
6. The pharmaceutical composition of claim 1 in the form of a chewable tablet.
7. The pharmaceutical composition of claim 1 wherein the potassium-binding polymer is in a bead form.
8. The pharmaceutical composition of claim 1 suitable for oral, intestinal, or rectal administration.
9. The pharmaceutical composition of claim 8 suitable for oral administration.
10. The pharmaceutical composition of claim 8 suitable for intestinal administration.
11. The pharmaceutical composition of claim 8 suitable for rectal administration.
