Effect of triamterene on potassium excretion in cirrhotic patients receiving furosemide.
In a three-way crossover study, 23 patients with hepatic cirrhosis, ascites, and dependent edema received 40 mg/day of furosemide alone and combined with triamterene 50 mg/day and triamterine 100 mg/day. Baseline potassium excretion did not increase when furosemide was given alone, but potassium excretion fell when 50 mg or 100 mg of triamterene was also given. Both doses of triamterene augmented the natriuretic effect of furosemide.
