Measure
Reformulated OXY (Test) First
Reformulated OXY 40-mg tablet (test) fed, dose administered in a two-period, two-sequence, single-dose, two-way crossover fashion. A minimum washout period of at least 6 days separated dose administrations. Subjects in this sequence received Reformulated OXY (Test) in period 1 and Original OxyContin(OXY)(Reference) in period 2.
Original OxyContin® (OXY) (Reference) First
Original OxyContin® (OXY) 40-mg tablet (reference) fed, dose administered in a two-period, two-sequence, single-dose, two-way crossover fashion. A minimum washout period of at least 6 days separated dose administrations. Subjects in this sequence received Original OxyContin® (OXY) (Reference)in period 1 and Reformulated OXY (Test) in period 2.
