- MetabollsmFollowing intravenous injection or infusion it undergoes metabolism in the liver to an active sulfoxide metabolite (piroximone).
- Half lifeIn healthy volunteers, 1 to 4 h, in patients with heart failure, 6 h (bolus injections), 8 h (continuous infusion); infants (0.6 to 49.7 weeks) 1.4 to 10.9 h (median 6.4); sulfoxide, 2.9 to 17.7 h (median 7.4).
