Primary Outcome Measures:
  • Pain Intensity Difference (PID) on a 0-100 VAS [ Time Frame: at 1.5 hours after treatment administration ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).


Secondary Outcome Measures:
  • PID [ Time Frame: at 15 minutes post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 30 minutes post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 45 minutes post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 60 minutes post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 90 minutes post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 2 hours post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 3 hours post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 4 hours post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 5 hours post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 6 hours post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 7 hours post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

  • PID [ Time Frame: at 8 hours post-dose. ]
    Pain intensity difference (PID) was derived by subtracting each pain intensity score (PI) from the baseline PI score (t0), where PI was assigned by the patient on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).

Criteria

Inclusion Criteria:

  • Patients undergoing surgical extraction of a single fully or partially impacted mandibular 3rd molar requiring bone removal.
  • Patients experiencing moderate to severe post-operative pain within 6 hours from end of surgery.
  • Pre-operative laboratory tests in the reference ranges or without clinically significant abnormalities as judged by the Investigator.

Exclusion Criteria:

  • Surgery performed under general anaesthesia, or sedation.
  • Complications occurring during the surgical procedure or in the period before randomisation as judged by the investigator.
  • Acute local or systemic infection at the time of surgery that could confound the post-surgical evaluation.
  • Patients with clinical signs of gastritis, gastro-duodenal ulcer, GI bleeding. Other GI disturbances or disease that in the opinion of the investigator could be negatively affected by the administration of NSAIDs.
  • Clinical signs or history of coagulation disorders that could be negatively affected by NSAIDs administration.
  • Hepatic or renal impairment.
  • Patients with significant cardiac impairment, history of cerebrovascular disease, history or peripheral arterial disease, uncontrolled hypertension.
  • Hypersensitivity to diclofenac or other NSAIDs or to one of the study medication components.
  • Patients under chronic treatment with topical or systemic analgesics/NSAIDs.
  • Patients under treatment with any medication that may affect the treatment efficacy evaluation.
  • Patients under treatment with any medication whose concomitant use may be susceptible to interactions with diclofenac or may affect safety.
