I plasma fandt man kun sporkoncentrationer af metabolitterne M- 1 og M- 2, mens M- 5, den mere udtalte metabolit, fandtes i en mængde svarende til 6, 5% af den oprindelige substans.
In plasma, metabolites M-1 and M-2 were detected only at trace concentrations and metabolite M-5, the more abundant metabolite, accounted for a total of 6.5% relative to parent compound.
