| pubmed-article:1793 | pubmed:abstractText | Although it is well recognized that mineralocorticoids enhance renal acid excretion, the effect of glucocorticoids on renal acidification is unclear. Oral administration of dexamethasone to six healthy volunteers for 1 week at a daily dose of 4.5 mg was associated with mild respiratory alkalosis and a small but statistically significant increase in baseline urine pH. However, neither the ability to lower urine pH nor to excrete titratable acid and ammonium after NH4Cl acid-loading was altered. Administration of a single intravenous dose of dexamethasone sodium phosphate (7.5 mg) was associated with a significant rise in urine pH and potassium excretion and decreased titratable acid, ammonium , and phosphorus excretion in the absence of changes in blood acid-base status, creatinine clearance, or urine flow. | lld:pubmed |
