Primary Outcome Measures

Name	Time	Method
Secondary Objective: Secondary objectives are to assess the safety, tolerability, and palatability of the tapentadol PR granule formulations. ;Primary end point(s): No endpoints have been defined for this trial.;Timepoint(s) of evaluation of this end point: No endpoints have been defined for this trial.;Main Objective: The primary objective of the trial is to assess the pharmacokinetics and relative bioavailability of tapentadol following administration of 3 prototype tapentadol PR granule formulations (test formulations) each containing 25 mg tapentadol, compared to 1 tablet of Palexia® PR 25 mg (reference formulation) under fasted and fed conditions. <br><br>The main pharmacokinetic target parameters are Cmax and AUC0-t for tapentadol.
