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.

Pain Area Under the Curve 0-8h (AUC0-8h)
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.
Time frame: 0-8 h(from end of surgery to 8 hours post surgery)
Pain Area Under the VAS Versus Time Curve 0-4h (AUC0-4h)
Area under the Visual Analogue Scale (VAS, 0-100 mm) time curve 0-4h (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.
Time frame: 0-4h (from end of surgery to 4 hours post surgery)
Maximum Pain Based on VAS Scale
Maximum pain recorded on a Visual Analogue Scale, VAS (0-100mm). Observed case. Maximum pain VAS (0-100mm, 0 = no pain - 100 = worst pain imaginable)
Time frame: From end of surgery to 8h or time first intake of rescue medication (whichever came first)
Mean Pain Based on a VAS Scale
Calculated as the area under the Visual Analogue Pain Scale (0-100 mm) versus time curve divided by time.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. Mean pain VAS (0-100mm, 0 = no pain - 100 = worst pain imaginable)
Time frame: From end of surgery to 8h or time to first intake of rescue medication (whichever came first)
Pain at Jaw Movement AUC0-8h
Area under the Visual Analogue Scale (VAS, 0-100 mm) of jaw movement versus 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. Area under the curve 0-8h (from end of surgery) of VAS pain at jaw movement (0-100mm, 0 = no pain - 100 = worst pain imaginable)

Maximum Pain at Jaw Movement
Maximum pain at jaw movement recorded on a Visual Analogue Scale, VAS (0-100mm). Observed case. Maximum Pain at jaw movement VAS (0-100mm, 0 = no pain - 100 = worst pain imaginable)

Mean Pain at jaw movement VAS (0-100mm, 0 = no pain - 100 = worst pain imaginable ).
Time frame: From end of surgery to 8h or time to first intake of rescue medication (whichever came first)
Pain at Rescue Medication
Pain at time of first rescue medication (VAS 0-100mm). Only patients taking rescue are included in analysis. Observed case. Pain at time of first rescue medication (VAS 0-100mm, 0 = no pain - 100 = worst pain imaginable).
Time frame: At time of first rescue medication taken before 8 hours after end of surgery
Pain at Jaw Movement at Time of First Rescue Medication

Number of Patients Requesting Rescue Medication
Observed case.
Time frame: End of surgery up to 8hours following surgery
Maximum Deterioration in Visual Analogue Mood Scale (VAMS) Stimulated
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. Subjects are required to rate on 100-mm lines the extent to which they felt each adjective at a given time point from 'not at all' on the left end of the scale to 'extremely' on the right end of the scale. The VAMS commonly used in studies with cannabinoids consists of six adjectives and visual analogue scales: stimulated; high (as in drug high, elated); anxious; sedated; down (as in moody, depressed) and hungry.
Time frame: Between dosing and 12h post-dose
