Ama-resin e-Cation-exchange resins asetshenziselwa ukwelapha i-hyperkalaemia ngokusheshisa ukulahleka kwe-potassium emathunjini, ikakhulukazi esimweni sokukhishwa okungalungile komchamo noma ngaphambi kwe-dialysis (izindlela eziphumelela kakhulu zokwelapha i-hyperkalaemia). Izinhlaka ziqukethe ukuhlanganiswa kwama-molecule amakhulu angaxazululeki athwala izindleko ezingaguquki, ezibopha ngokukhululekile ama-ion (cations); lezi zishintshana kalula nama-cations endaweni enoketshezi ngezinga elixhomeke ebuhlotsheni babo be-resin kanye nokuhlushwa kwabo.
Izinhlaka ezilayishwe ngokushintshaniswa kwe-sodium noma i-calcium lezi zinhlayiya zikhetha ngokukhethekile i-potassium cations emathunjini (cishe u-1 mmol potassium nge-resin ngayinye); ama-cations akhululiwe (i-calcium noma i-sodium) ayangena futhi i-resin kanye ne-potassium eboshiwe idluliselwa endle. I-resin ayigcini nje ngokuvimbela ukumuncwa kwe-potassium efakiwe, kodwa futhi ithatha i-potassium evame ukufihlwa emathunjini futhi ivame ukubuyiselwa kabusha.
Ku-hyperkalaemia, ukuphathwa ngomlomo noma ukugcinwa kwe-resin ye-polystyrene sulphonate resin kungasetshenziswa. I-resin yesigaba sesodium (i-Resonium A) ngokusobala akumele isetshenziswe ezigulini ezinokwehluleka kwezinso noma zenhliziyo njengoba kungenzeka ukugcwala ngokweqile kwe-sodium. I-resin yesigaba se-calcium (iCalcium Resonium) ingadala i-hypercalcaemia futhi kufanele igwenywe ezigulini ezibekiwe, isib. Ngomlomo azidleki, futhi njengoba iziguli ezine-enemas zivame ukuphatha ukuzigcina isikhathi eside ngangokunokwenzeka (okungenani i-9 h) ukushintshanisa i-potassium kuzo zonke izingosi ezitholakalayo ku-resin.
