Elevated blood pressure (BP) is common in CKD, due in part to impaired sodium excretion. The effect of patiromer, which exchanges calcium for potassium and SZC, which exchanges sodium or hydrogen for potassium, on BP was assessed in a CKD rat model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Thirty-six Sprague Dawley rats with 5\/6 nephrectomy were randomised to three groups (n\u2009=\u200912\/group) to receive 4\u2005g\/kg\/day patiromer or SZC, or vehicle treatment, for 8 weeks.

Similar results were observed for diastolic BP. Serum potassium levels fell with SZC ( p\u2009&lt;\u20090.02), but not vehicle or patiromer. Urine potassium decreased with both patiromer and SZC versus vehicle ( p\u2009&lt;\u20090.01); urine sodium increased with SZC ( p\u2009&lt;\u20090.01); and urine calcium increased with patiromer ( p\u2009&lt;\u20090.01). Urine phosphorus decreased with patiromer ( p\u2009&lt;\u20090.01) but increased with SZC ( p\u2009&lt;\u20090.01).
