This is a randomized (study drug assigned by chance like flipping a coin), double-blind (neither physician nor patient knows the name of the assigned drug), placebo-controlled, parallel-group, multicenter study to evaluate the efficacy and safety of tapentadol immediate-release (IR) 50 mg and 75 mg in patients who are undergoing bunionectomy (a surgical procedure to remove a bunion). This study was designed to be a similar study to the pivotal global study of PAI-3003/KF32 in order to bridge the results from the global studies and to show similarity in effect of tapentadol between Korean and Caucasian population which will allow extrapolation of the foreign clinical data of tapentadol into Korea. The study will be divided into screening period, surgical period, qualification period, and a double-blind treatment period. The study length, including the screening period, will be up to a maximum duration of 32 days. Eligible patients will be randomly assigned to 1 of 3 treatment groups (tapentadol IR 50 mg, tapentadol IR 75 mg or placebo) in a 1:1:1 ratio. Efficacy and safety assessments will be performed during the study.
