In a previous study it has been demonstrated that a dissolution/permeation (D/P) system can discriminate between different immediate release fenofibrate formulations. The fractions permeated were correlated with fenofibrate's in vivo exposure in rats following p.o. administration. In the present study more detailed investigations are presented using data from six fenofibrate tablets tested in vivo in humans. In these pharmacokinetic studies no significant differences between formulations in AUC but in Cmax were found. Differences between the Cmax values were not explained by the dissolution characteristics of the tablets but were rationalized on the basis of micellar entrapment and diminished mobility of the active ingredient by surfactants in the formulations. This was demonstrated by a permeation system using dialysis membranes. Thus a permeation step in addition to dissolution measurement may significantly improve the establishment of an IVIV relationship.
