I-resin-exchange resins isetyenziselwa ukunyanga i-hyperkalaemia ngokukhawulezisa ilahleko ye-potassium emathunjini, ngakumbi kwimeko yokukhutshwa komchamo ongekho mgangathweni okanye ngaphambi kwe-dialysis (ezona ndlela zisebenzayo zokunyanga i-hyperkalaemia). Ii-resins ziqulathe ukudityaniswa kweemolekyuli ezinkulu ezingenakunyibilika ezithwele iirhafu ezingaguqukiyo, ezibopha ngokukhululekileyo ii-ion ezihlawulisiweyo (cations); Oku kutshintshiselana ngokulula kunye neekhemikhali kwindawo enamanzi ukuya kuthi ga kwinqanaba elixhomekeke kubumbano lwayo kwintlaka kunye nokuxinana kwabo.
Ii-Resins zilayishwe nge-sodium okanye nge-calcium ukutshintshiselana ngezi ndawo ngokukhetha i-potassium cations emathunjini (malunga ne-1 mmol potassium nge-resin nganye); ikati ekhululiweyo (ikhalsiyam okanye isodiyam) iyatsalwa kwaye i-resin kunye ne-potassium ebotshiweyo igqithiselwa kwilindle. I-resin ayikhuseli nje ukufunxwa kwe-potassium efakiweyo, kodwa ikwathabatha i-potassium edla ngokufihlwa emathunjini kwaye ibuye iphinde ibuyiselwe.
Kwi-hyperkalaemia, ulawulo lomlomo okanye i-enemas ye-polystyrene sulphonate resin inokusetyenziswa. I-resin-phase resin (Resonium A) ngokucacileyo ayinakusetyenziswa kwizigulana ezine-renal okanye ukusilela kwentliziyo njengoko ukugcwala kwesodium kungakhokelela. I-resin ye-calcium-resin (iCalcium Resonium) inokubangela i-hypercalcaemia kwaye kufuneka ithintelwe kwizigulana ezichongiweyo, umz. Ngomlomo azinakuthelekiswa nanto, kwaye njengoko izigulana ezingenayo imonyisiki kunqabile ukuba zikwazi ukuzigcina ixesha elide njengoko kufuneka (ubuncinci i-9 h) ukutshintshisa i-potassium kuzo zonke iindawo ezikhoyo kwi-resin.
