Hydrochlorothiazide inhibits sodium reabsorption in the distal tubule while amiloride blocks epithelial sodium channels, providing potassium-sparing diuresis.
Monitor electrolytes, especially potassium. Contraindicated with hyperkalemia. May reduce calcium excretion (useful for calcium oxalate stone prevention).
Species-specific contraindications and adverse-reaction reports for cats may differ from canine / feline reference data — consult the primary citations listed with each rule.
