Inclusion Criteria
  • Before Surgery

    • Participants scheduled to undergo a primary unilateral bunionectomy with distal first metatarsal osteotomy (i.e., Austin procedure) and internal fixation under regional anesthesia (Mayo and popliteal sciatic block)
  • After Surgery

    • Participant is lucid and able to follow commands
    • All analgesic guidelines were followed during and after the bunionectomy

Key

Exclusion Criteria
  • Before Surgery

    • Prior history of bunionectomy or or other foot surgery on the index foot; or bunionectomy on the opposite foot
    • History of cardiac dysrhythmias within the last 2 years requiring anti-arrhythmia treatment(s)
    • Any prior surgery within 1 month before the first study drug dose
  • After Surgery

    • Participant had a type 3 deformity requiring a base wedge osteotomy, concomitant surgery such as hammertoe repair; or experienced medical complications during the bunionectomy
