Prolonged Cation-Exchange Resin Therapy in Congestive Heart Failure

Abstract
IN THE past few years increasing clinical interest has been manifested in the ion-exchange resins. These are of two principal types, anion and cation. Anion-exchange resins have been used as antacids and pepsin inhibitors in the management of patients with peptic ulcer.1 2 3 4 5 6 Cation-exchange resins are of two common types: sulfonated and carboxylated.
