How Does Heparin Cause Hyperkalemia !!link!! -

The defining feature of heparin-induced hyperkalemia is a , resulting from the direct pharmacological suppression of steroidogenesis in the adrenal cortex.

The effect is dose-dependent and reversible upon heparin discontinuation. If continued, recovery may take several days after stopping the drug. how does heparin cause hyperkalemia

Aldosterone normally acts on the collecting duct of the kidney to increase sodium reabsorption and potassium secretion via epithelial sodium channels (ENaC) and Na⁺/K⁺-ATPase pumps . With less aldosterone, potassium secretion decreases, leading to potassium retention. The defining feature of heparin-induced hyperkalemia is a

Highly implicated, especially at therapeutic doses (e.g., >20,000 IU/day).
