Heparin Hyperkalemia Mechanism 🎯 No Ads

: Reduced renal potassium excretion leads to positive potassium balance, gradually raising serum potassium levels. This effect is typically mild (e.g., rising from 4.0 to 5.2–5.5 mEq/L) but can become severe (hyperkalemia) if:

Aldosterone levels begin to drop within a few days of starting therapy. heparin hyperkalemia mechanism

Heparin is a sulfated glycosaminoglycan that acts as an anticoagulant by binding to antithrombin III (ATIII), enhancing its inhibitory activity against thrombin and factor Xa. This binding also increases the release of potassium ions from cells, which can contribute to hyperkalemia. : Reduced renal potassium excretion leads to positive
