Ma resin osinthana a Cation amagwiritsidwa ntchito pochiza matenda a hyperkalaemia pofulumizitsa kutayika kwa potaziyamu kudzera m'matumbo, makamaka potulutsa mkodzo wochepa kapena dialysis isanafike (njira yothandiza kwambiri yochizira hyperkalaemia). Zitsulozi zimakhala ndi magulu akuluakulu a mamolekyulu osasungunuka omwe amakhala ndi milandu yolakwika, yomwe imamangiriza ma ion (ma cations); izi zimasinthana mosavuta ndi cations m'malo amadzimadzi momwe zimadalira kuyandikana kwawo kwa utomoni ndi kusakanikirana kwawo.
Zitsulo zodzaza ndi sodium kapena calcium zimasinthana izi makamaka ndi potaziyamu m'matumbo (pafupifupi 1 mmol potaziyamu pa g resin); ma cations omasulidwa (calcium kapena sodium) amalowetsedwa ndipo utomoni kuphatikiza potaziyamu umadutsa ndowe. Utomoniwu sikuti umangoteteza kuyamwa kwa potaziyamu wolowetsedwa, koma umatenganso potaziyamu yomwe nthawi zambiri imatulutsidwa m'matumbo ndipo imabwezeretsedwanso.
Mu hyperkalaemia, kugwiritsa ntchito pakamwa kapena kusungitsa utomoni wa polystyrene sulphonate resin kungagwiritsidwe ntchito. Sodium-phase resin (Resonium A) sayenera kugwiritsidwa ntchito kwa odwala omwe ali ndi vuto la impso kapena mtima chifukwa cha kuchuluka kwa sodium kungachitike. Katemera wa calcium-calcium (Calcium Resonium) amatha kuyambitsa matenda a hypercalcaemia ndipo amayenera kupewedwa mwa odwala, monga omwe ali ndi myeloma, metastatic carcinoma, hyperparathyroidism ndi sarcoidosis. Pakamwa ndiosawoneka bwino, ndipo odwala omwe ali ndi vuto losowa magazi nthawi zambiri samatha kuwasunga kwa nthawi yayitali (osachepera 9 h) kusinthanitsa potaziyamu pamalo onse omwe alipo pa utomoni.
