- Discussion: - is a potassium removing resin, for
hyperkalemia; - works as cation exchange resin, Na for K; - because of its delayed action, a cation exchange resin such as sodium sulfonate should be used only in mild cases of hyperkalemia or in catabolic patients with continuous release of intracellular potassium;
- Precautions: - caution w/ CHF, marked edema, or severe
HTN, due to high Na load; - must monitor K, Mg, and Ca; (
hypomagnesemia &
hypocalcemia) - concomitant administration of MgOH, non-absorbable cation donating antacids, and laxatives should be avoided; (See
SORBITOL)
- Dosage: - dose of 15 to 20 gm tid to qid may be taken orally or by retention enema; - adult: 15gm-60gm PO suspension (3-4ml/gm) q6hr prn; - 70%
