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.
Serum potassium levels greater than 5 mmol/L were observed during trimethoprim treatment in 15 of 30 patients. Rats: Intravenous trimethoprim inhibited renal potassium excretion by 40% (CI, 21% to 60%) and increased renal sodium excretion by 46% (CI, 9% to 83%).
