Evaluate Analgesic/Sedative Efficacy of Naproxen Sodium and Diphenhydramine in Patients With Postsurgical Dental Pain

Registration Number
NCT01280591
Lead Sponsor
Bayer
Brief Summary

The objective of the study is to evaluate the efficacy and safety of a single oral dose of two dose combinations of naproxen sodium and diphenhydramine (DPH) to demonstrate that naproxen sodium/DPH combination provides added clinical benefit to sleep improvement than either single ingredient alone in subjects with post-surgical dental pain and phase advanced sleep.

Inclusion Criteria
  • Healthy, ambulatory, male and female volunteers ages 12 and older

  • Scheduled to undergo surgical removal of a minimum of two third molars of which at least one has to be a mandibular third molar. The mandibular extraction(s) required by each subject must meet one of the following scenarios:

    • one full bony impaction
    • two partial bony impactions
    • one full bony impaction and one partial bony impaction
    • one full bony impaction and one soft tissue impaction
    • one full bony impaction and one erupted third molar. Two full bony mandibular impactions are not allowed. Maxillary third molars may be removed regardless of impaction level.
  • Have moderate to severe postoperative pain on the Categorical Pain Rating Scale and a score of ≥ 50 mm on the 100-mm visual analog Pain Severity Rating Scale between 1600 hour and 1830 hour on the day of surgery

  • 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, Depo-Provera, or double-barrier and have a negative pregnancy test at Screening and prior to surgery. Female subjects of nonchildbearing potential must be amenorrheic for at least 2 years or had a hysterectomy and/or bilateral oophorectomy

  • Provide a personally signed and dated informed consent 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
  • History of hypersensitivity to naproxen, diphenhydramine, nonsteroidal anti-inflammatory drug (NSAIDS), tramadol, aspirin or any other antihistamine and similar pharmacological agents or components of the products
  • Evidence or history of clinically significant (in the judgment of the investigator) hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic diseases, or malignancies within the last 5 years
  • Relevant concomitant disease such as asthma (exercise induced asthma is permitted), chronic sinusitis or nasal structural abnormalities causing greater than 50 percent obstruction (polyposis nasi, marked septal deviation) that can interfere with the conduct of the study in the judgment of the investigator
  • Current or past history of bleeding disorder(s)
  • Acute illness or local infection prior to surgery that can interfere with the conduct of the study in the judgment of the investigator
  • Chronic use of antihistamines defined as using 5 or more times a week for 2 or more consecutive weeks during the past 3 months
  • Positive alcohol breathalyzer test and positive urine drug test prior to surgery
  • Females who are pregnant or lactating
  • Chronic or severe sleep problems that do not respond to / Over the Counter (OTC) medication and requires a prescription hypnotic or sedative

Primary Outcome Measures
NameTimeMethod
Wake Time After Sleep Onset (WASO) Measured by ActigraphyUp to 10 hours

WASO was defined as Total wake time (in minutes) after sleep onset during the 10 hours in-bed period as measured by actigraphy. Actigraphy is a non-intrusive tool that measures an individual's movement during sleep. Actigraphy was used to obtain data in discriminating between sleep and wake states in the subjects.

Sleep Latency Measured by ActigraphyUp to 10 hours

Sleep latency was defined as the time to sleep onset from the time of dosing as measured by actigraphy. Actigraphy is a non-intrusive tool that measures an individual's movement during sleep. Actigraphy was used to obtain data in discriminating between sleep and wake states in the subjects.

Secondary Outcome Measures
NameTimeMethod
Karolinska Sleep Diary - Ease of AwakeningUp to 10 hours

Subjects responded to the following question: Ease of awakening? (1) very difficult; (2) rather difficult; (3) neither difficult nor easy; (4) rather easy; very easy (5)

Karolinska Sleep Diary - Sleep QualityUp to 10 hours

Subjects responded to the following question: How was your sleep? very poor (1); rather poor (2); neither poor nor good (3); rather good (4); very good (5)

Karolinska Sleep Diary - Calmness of SleepUp to 10 hours

Karolinska Sleep Diary - Premature AwakeningUp to 10 hours

Subjects responded to the following question: Premature awakening? woke up much too early (1); woke up somewhat too early (2); no (3)

Total Sleep Time Measured by ActigraphyUp to 10 hours

Total time time was measured as total time spent sleeping (not to exceed 600 minutes) during the in-bed period as measured by actigraphy. Actigraphy is a non-intrusive tool that measures an individual's movement during sleep. Actigraphy was used to obtain data in discriminating between sleep and wake states in the subjects.

Sleep Efficiency Measured by ActigraphyUp to 10 hours

Sleep efficiency was calculated as (total sleep time/total time in-bed time) × 100; total in-bed time was fixed at 10 hours. Actigraphy is a non-intrusive tool that measures an individual's movement during sleep. Actigraphy was used to obtain data in discriminating between sleep and wake states in the subjects.
