Use of sodium polystyrene sulfonate (SPS) dominates the long-term treatment of hyperkalemia, but two new agents, sodium zirconium cyclosilicate and the recently FDA-approved patiromer, may offer potential advantages compared with SPS.

Cation-exchange resins are used in the management of hyperkalemia, particularly in patients with end-stage renal disease. These resins were associated with gastrointestinal tract lesions, especially sodium polystyrene sulfonate (Kayexalate) mixed with sorbitol. We present a case of colonic necrosis after the administration of calcium polystyrene sulfonate (Kalimate) not suspended in sorbitol.

The metabolism of the fungicide Dexon (p-dimethylaminobenzenediazo sodium sulfonate) by a soil bacterium is reported for the first time. The organism which is capable of using Dexon only by a co-metabolic process was obtained by enrichment culture and was identified as Pseudomonas fragi. The first metabolic product of Dexon was identified as N,N-dimethyl-p-phenylenediamine. The presence of an e...

Severe hyperkalemia requires urgent medical attention and correction in order to prevent arrhythmic complications. Sodium polystyrene sulfonate (SPS) is a cation exchange resin commonly used in the management of hyperkalemia. A recent review raised concerns regarding its effectiveness and potential adverse effects. Hypernatremia in adults in the setting of sodium polystyrene sulfonate therapy h...

Rice starch is used as an additive in various food and industrial products. With the inherent merits of small and uniform size distribution of rice starch and its white color and clean odor, deserts and bakery products are some of the favorable applications among processed foods [1]. The small granular size of the starch imparts it soft texture, high water retention and low syneresis, suggestin...
