  Purpose

The primary aim of this study is to investigate if AZD1940 can relieve the pain induced by the surgical removal of one lower wisdom-tooth. This will be done by comparing the effect of AZD1940 to placebo ("inactive substance") on pain. A number of patients will instead receive the common painkiller naproxen for comparison purposes. Rescue medication, acetaminophen, will be allowed if a need for additional painkillers would arise. A number of patients will receive Naproxen as control.

Primary Outcome Measures:
  • Pain Area Under the Curve 0-8h (AUC0-8h) [ Time Frame: 0-8 h(from end of surgery to 8 hours post surgery) ] [ Designated as safety issue: No ]
    Area under the Visual Analogue Scale (VAS, 0-100 mm) time curve 0-8h (from end of surgery). Missing values in the pain-by-time curve was imputated using linear interpolation, last observation carried forward (LOCF) or first observation carried backwards (FOCB) as applicable.

  • Maximum Deterioration in Visual Analogue Mood Scale (VAMS) Stimulated [ Time Frame: Between dosing and 12h post-dose ] [ Designated as safety issue: No ]
    Subjective qualities of mood in the subject are measured by letting the subject rate their subjective experiences of a number of adjectives using a series of visual analogue scales.
