Renal Mechanism of Trimethoprim-induced Hyperkalemia. From the Department of Veterans Affairs Medical Center, West Haven, Connecticut; Yale University School of Medicine, New Haven, Connecticut.
Hyperkalemia may occur when one of these mechanisms is impaired because of renal failure, renal hypoperfusion (e.g., volume depletion, congestive heart failure), or hypoaldosteronism. Hypoaldosteronism may be the cause of hyperkalemia in patients who do not have advanced renal failure or hypoperfusion.11.
