title: Application of a simple fluorometric method on absorption of canrenone.
abstract: The absorption of canrenone, the major metabolite of spironolactone, was studied by a simple fluorometric method in 30 healthy subjects. Two different pharmaceutical formulations were compared on absorption, and only a negligible difference was found between the micronized and balled-milled form. Canrenone in both formulations was well absorbed, whereas spironolactone absorption was slower. Mattingly's fluorometric assay proved to be a simple method to evaluate the absorption of canrenone.
