title: Pharmacokinetics of dexibuprofen administered as 200 mg and 400 mg film-coated tablets in healthy volunteers.
abstract: The pharmacokinetic properties of 2 film-coated preparations containing 200 mg and 400 mg dexibuprofen were compared in a single-dose, crossover study in 16 healthy, male volunteers. Dexibuprofen was absorbed rapidly (tmax 2.1 - 2.2 hours) reaching maximum concentrations of 12.4 microg/ml (200 mg), respectively 12.0 microg/ml (400 mg dose adjusted). For the characteristics AUC(0-12h) and AUC(0-infinity) arithmetic means of 49.2 (microg) x (h/ml)(200 mg) and 48.2 (microg) x (h/ml)(400 mg dose-adjusted), respectively 50.5 (microg) x (h/ml)(200 mg), and 49.2 (microg) x (h/ml)(400 mg) were calculated. No relevant differences for the pharmacokinetic characteristics terminal half-life, clearance, volume of distribution, and mean residence time were observed. A linear dose-relationship was shown over the investigated dose range. Mean ratios after dosage adjustment of the test preparation using the "2 one-sided t-tests" procedure were calculated. Bioequivalence was assessed for AUC(0-12h) with a mean ratio of 97.7% (90% CI: 92.4 - 103.3%), for AUC(0-infinity) with 97.1% (90% CI: 91.4 - 103.1%), and for Cmax with 97.5% (90% CI: 91.7 - 103.8%). Both dexibuprofen preparations were well tolerated. No changes in hematological and biochemical parameters were detected.
