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 title salt, C(5)H(6)N(+)·C(7)H(4)F(3)O(3)S(-), is an ion pair in which the pyridium cation is linked to the 4-(trifluoro-meth-yl)benzene-sulfonate anion by an N-H⋯O hydrogen bond. The F atoms of the trifluoro-methyl group are disordered over two sites in a 0.584 (9):0.416 (9) ratio.

Alkaline phosphatase from human liver was purified to homogeneity. The purification procedure included solubilization with butanol, fractionation with acetone, and chromatography on concanavalin A-Sepharose, DEAE-cellulose, Sephadex G-200 and DEAE-Sephadex. Purity was established by standard and sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. The isoelectric point of the protein was...

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...
