Primary Outcome Measures:
  • Pain on Movement [ Time Frame: 72 hours ] [ Designated as safety issue: No ]
    Pain on movement at 72 hours assessed on a 100 mm visual analog scale with anchors at 0= "No pain" and 100= "Extreme pain"


Secondary Outcome Measures:
  • Pain on Movement [ Time Frame: 24 hours and 7 days ] [ Designated as safety issue: No ]
    Pain on movement at 24 hours and 7 days assessed on a 100 mm visual analog scale with anchors at 0= "No pain" and 100= "Extreme pain"

  • Onset of Pain Relief [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Onset of perceptible pain relief

  • Tenderness [ Time Frame: Change from baseline at 24 and 72 hours, 7 days ] [ Designated as safety issue: No ]
    Tenderness at 24 and 72 hours and 7 days. Change from baseline. Tenderness was measured by a calibrated algometer in order to quantify the pressure pain threshold, a measure of tenderness.

  • Ankle Joint Function [ Time Frame: 24 and 72 hours, 7 days ] [ Designated as safety issue: No ]
    Ankle joint function score (Karlsson Scoring scale which ranges from 0 "worst possible score" to 90 "best possible score")at 24 and 72 hours and 7 days.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion criteria:

  1. Male or female aged 18 years and over.
  2. Acute sprain of the lateral ankle, Grade I-II, meeting baseline pain intensity level.
  3. Injury within past 12 hours.

Exclusion criteria:

  1. Pain medication was taken within the 6 hours that precede randomization.
  2. During the past 3 months: Grade I-III sprain of the same ankle.
  3. During the past 6 months: Grade II-III sprain, any other significant injury (such as fracture or torn ligament), or surgery (except for skin or nails) of the same ankle or foot.
  4. Pain or instability in the same ankle attributable to previous ankle sprain or any other trauma.
  5. Ankle sprain attributable to a known disease affecting the ligaments, such as ligament hyperlaxity due to connective tissue disease (e.g., Marfan's syndrome, Down's syndrome, Ehlers-Danlos syndrome).

Other protocol-defined inclusion/exclusion criteria may apply
