Inclusion criteria

* Healthy, ambulatory, male and female volunteers 15 years of age and above * Scheduled to undergo surgical removal of up to two impacted third molars, one of which must be mandibular full or partial bony impaction and the other a maxillary impaction * Female subjects of childbearing potential must be using a medically acceptable form of birth control for at least 1 month prior to screening (3 months on oral contraceptives), e.g., oral or patch contraceptives, intrauterine device, NuvaRing, Depo-Provera, or double-barrier and have a negative pregnancy test at Screening and prior to surgery * Have not taken any form of medication or herbal supplements (ie, St. Johns Wort) within 5 days of admission (except for oral contraceptives, prophylactic antibiotics, or other routine medications to treat benign conditions, such as antibiotics to treat acne) and agree not to take any medication (other than that provided to them) throughout the study * Have not consumed alcoholic beverages, or foods and beverages containing xanthines (examples, coffee, tea, chocolate, and colas) after midnight prior to surgery and agree not to consume any of these foods or beverages throughout the evaluation period * Use of only short-acting local anesthetic (e.g., mepivacaine or lidocaine) preoperatively, with or without vasoconstrictor and nitrous oxide * Have moderate to severe postoperative pain on the Categorical Pain Intensity Scale (a score of at least 2 on a 4 point scale) and a score of ≥ 50 mm on the 100 mm Visual Analog Scale (VAS) within 4 hours postsurgery, but no later than 1330 hours +/- 15 minutes * Understand the pain rating scales (as judged by the study coordinator) * Be willing and able to participate in all scheduled visits, treatment plan, tests and other trial procedures according to the protocol * Provide a personally signed and dated informed consent form (ICF) indicating that the subject has been informed of all pertinent aspects of the trial, (subjects \< 18 years of age must sign a written assent and have parental or guardian consent)

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
Summed, Time-weighted Pain Intensity Difference From 0 to 24 Hours Postdose (SPID0-24)From 0 to 24 hours post-doseSPID0-24 was calculated by multiplying the pain intensity difference score at each post-dose timepoint by the duration (in hours) since the preceding timepoint and then summing these values over 0 to 24 hours. Pain intensity was measured at baseline, 0.25, 0.5, 0.75, 1, 2, 3, 4, 5, 6, 8, 12, 16, 20 and 24 hours using the 4-point categorical pain intensity scale: 0 = none, 1 = mild, 2 = moderate, 3 = severe. SPID0-24 can vary from -24 to 72. The positive SPID value indicates improvement of pain relief. The higher the SPID value, the more improvement of pain relief.

MeasureTime frameDescription
Summed, Time-weighted Total Pain Relief Scores (TOTPARs)0-6, 0-8, 0-12, 0-16, 0-24, and 16-24 hours postdoseTOTPARs were derived by multiplying the pain relief score at each post-dose timepoint by the duration (in hours) since the preceding timepoint and then summing these values over the specified interval. Pain Relief was evaluated at 0.25, 0.5, 0.75, 1, 2, 3, 4, 5, 6, 8, 12, 16, 20 and 24 hours postdose, using the 5-point overall pain relief scale: 0 = No relief, 1 = A little relief, 2 = Some relief, 3 = A lot of relief, 4 = Complete relief. The possible total score ranges of TOTPARs are: TOTPAR0-6: 0 to 18, TOTPAR0-8: 0 to 24, TOTPAR0-12: 0 to 36, TOTPAR0-16: 0 to 48, TOTPAR0-24: 0 to 72, TOTPAR16-24: 0 to 24.

Summed, Time-weighted Pain Intensity Differences (SPID)

Pain intensity was measured at baseline, 0.25, 0.5, 0.75, 1, 2, 3, 4, 5, 6, 8, 12, 16, 20 and 24 hours using the 4-point categorical pain intensity scale: 0 = none, 1 = mild, 2 = moderate, 3 = severe. The total possible score ranges of SPIDs are SPID0-6: -6 to 18, SPID0-8: -8 to 24, SPID0-12: -12 to 36, SPID0-16: -16 to 48, SPID16-24: -8 to 24. The positive SPID value indicates improvement of pain relief. The higher the SPID value, the more improvement of pain relief.

Time frame: 0-6, 0-8, 0-12, 0-16 and 16-24 hours postdose

Summed, Time-weighted Total Pain Relief Scores (TOTPARs)

TOTPARs were derived by multiplying the pain relief score at each post-dose timepoint by the duration (in hours) since the preceding timepoint and then summing these values over the specified interval. Pain Relief was evaluated at 0.25, 0.5, 0.75, 1, 2, 3, 4, 5, 6, 8, 12, 16, 20 and 24 hours postdose, using the 5-point overall pain relief scale: 0 = No relief, 1 = A little relief, 2 = Some relief, 3 = A lot of relief, 4 = Complete relief. The possible total score ranges of TOTPARs are: TOTPAR0-6: 0 to 18, TOTPAR0-8: 0 to 24, TOTPAR0-12: 0 to 36, TOTPAR0-16: 0 to 48, TOTPAR0-24: 0 to 72, TOTPAR16-24: 0 to 24.
