[Comparison of the pharmacokinetics of a quick-release bezafibrate formulation with a sustained-release formulation. 1. Single-dose administration].

Comparison of the Pharmacokinetic Profiles of a Quick and a Sustained Release Bezafibrate Formulation/1st Communication: Single-dose application The hypolipaemic agent bezafibrate (CAS 41859-67-0) is available as immediate and sustained release formulation. The pharmacokinetic profile of an immediate release 300 mg dragee (A) was compared in a two-way cross-over design to that of a 400 mg sustained release dragee (B). Neglecting the dose difference, the AUEC of A (28.8 micrograms/ml.h) was equal to that of B (27.6 micrograms/ml.h), whereas the bioavailability of A appeared to be higher than that of B when AUEC was corrected for dose (AUEC ratio = 137%). Regarding Cmax and tmax, both formulations exhibited the expected differences.
