Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • 18-65 years of age
  • Have undergone bunionectomy surgery
  • Have achieved adequate post-surgical pain

Treatment and study plan

diclofenac potassium (XP21L)

Drug

25 mg every 6 hours

Other names: Zipsor Liquid Filled Capsule, XP21L

Placebo

Drug

Placebo every 6 hours

Primary outcomes

  1. Average Numeric Pain Rating Score (NPRS) Over 48 Hours After Bunionectomy

    Time frame: Over 48 hours after bunionectomy

    Pain intensity scores were measured using an 11-point numerical pain rating scale (NPRS) with 0=no pain to 10=worst possible pain

Secondary outcomes

  1. Number of Patients With Perceptible Pain Relief on Day 1

    Time frame: 8 hours post single dose

    Times to onset of Perceptible and Meaningful Relief were determined using the double-stopwatch method.

  2. Median Time to Onset of Pain Relief in Patients With Perceptible Pain Relief on Day 1

    Time frame: 8 hours post single dose

  3. Number of Patients With Meaningful Pain Relief on Day 1

    Time frame: 8 hours post single dose

    Times to onset of Perceptible and Meaningful Relief were determined using the double-stopwatch method.

  4. Median Time to Onset of Pain Relief in Patients With Meaningful Pain Relief on Day 1

    Time frame: 8 hours post single dose

  5. Total Pain Relief (TOTPAR) Scores 8 Hours Post Initial Dose of Study Drug

    Time frame: 8 hours post single dose

    Pain relief was rated using a 5-point categorial scale (0=none, 1=a little, 2=some, 3=a lot, and 4=complete) at time of dose (time=0) and over 15 time points afterwards (10, 15, 20, 30, 45, and 60 minutes and at 1.5, 2, 2.5, 3, 4, 5, 6, 7, and 8 hours after the initial dose on Day 1 or until time of re-medication). A score of 0 across all time points would be the lowest (worst) and a score of 60 (4 X 15 time points) would be the highest (best) possible score.

  6. Number of Patients With at Least 30% Reduction in Pain Intensity After First Dose of Study Drug

    Time frame: 8 hours post single dose

  7. Time to Onset of at Least 30% Reduction in Pain Intensity After First Dose of Study Drug

    Time frame: 8 hours post single dose

  8. Number of Patients Who Required Rescue Medication on Day 1

    Time frame: Day 1

  9. Number of Patients Who Required Rescue Medication on Day 2

    Time frame: Day 2

  10. Number of Patients Who Required Rescue Medication on Day 3

    Time frame: Day 3

    Day 3 data reflect the use of rescue medication only up to the time of discharge
