title: Elimination of canrenone in congestive heart failure and chronic liver disease.
abstract: The elimination half-life (T1/2) of canrenone, the principal unconjugated metabolite of spironolactone, was 59 h (range 32-105 h) in 5 patients with chronic liver disease and 37 h (range 19-48 h ) in 7 patients withcongestive heart failure. In comparison the T1/2 in normal subjects was 13.5-24 h in previous reports and 20.5 h in the present study, However there was no evidence of greater cumulation of canrenone in the plasma of those patients with a prolonged T1/2.
