    Paradoxical potassium excretion in response to aldosterone antagonists (1977)
    Springer

    Notes: Summary The activity of two aldosterone antagonists in reversing the urinary electrolyte changes induced by the mineralocorticoid fludrocortisone was examined in healthy subjects. Between 2–10 h after treatment there were dose-related increases in sodium excretion and the urine log 10 Na/K ratio, but no significant changes in urine volume, potassium concentration, or potassium excretion. Between 12–16 h after treatment there were dose-related increases in urine sodium excretion and the log 10 Na/K ratio. Unexpectedly, there were significant dose-relatedincreases in potassium excretion despite significant dose-related reductions in urinary potassium concentration. The paradoxical increases in potassium excretion were attributed to dose-related increases in urine volume in the same period. These observations may explain the increased potassium excretion occasionally observed during clinical use of aldosterone antagonists and suggest that potassium excretion in man is influenced by the urine flow rate.

    Influence of acetylsalicylic acid on the renal handling of a spironolactone metabolite in healthy subjects (1976)
    Springer
    European journal of clinical pharmacology 10 (1976), S. 43-48 
    Details
    ISSN: 1432-1041
    Keywords: Spironolactone ; acetylsalicylic acid ; fludrocortisone ; kinetics ; pharmacology ; interaction

    Notes: Summary The influence of 600 mg acetylsalicylic acid (ASA) on the renal excretion and clearance of canrenone, the principal unconjugated metabolite of spironolactone, was examined in a double-blind crossover study in six healthy subjects. ASA significantly reduced the urinary excretion, and the fractional excretion, of canrenone between 4 — 6 hours after administration of 50 mg spironolactone. The pharmacological activity of spironolactone, assessed simultaneously by alterations in fludrocortisone-induced urinary electrolyte changes, was slightly but not significantly reduced. The reductions in urinary canrenone excretion correlated with changes in the urinary log 10 Na/K ratio. The results suggest that canrenone may be actively secreted at the proximal renal tubule, and that secretion is blocked by ASA or its conjugates. This is a possible mechanism for the pharmacological interaction between ASA and spironolactone which has been described previously.
