Aldosterone and Potassium Regulation
- Reduced aldosterone leads to decreased potassium excretion in the distal nephron.
- This causes increased potassium levels and type 4 renal tubular acidosis.
Human Studies on Aldosterone Reduction
- Studies confirm heparin's aldosterone-reducing effect in humans.
- Even low doses used for DVT prophylaxis show a reduction, similar to therapeutic doses.
Heparin in Hyperaldosteronism
- Heparin can suppress aldosterone even in patients with hyperaldosteronism.
- A case series showed a five-fold reduction in aldosterone, improving hypertension and increasing potassium.
