Bayer Consumer Health Announces Data From Two Single-Dose Studies at Annual ADA Meeting
WHIPPANY, N.J., Sept. 6, 2019 /PRNewswire/ -- Bayer today announced data that showed Aleve® (naproxen sodium) provided more pain relief from hour three onward than acetaminophen plus codeine after wisdom tooth removal. The results were presented at the American Dental Association (ADA) FDI World Dental Congress, taking place in San Francisco from September 4-8, 2019.
Aleve® is an over-the-counter (OTC) pain reliever indicated for temporary relief of minor aches and pains including minor arthritis pain, headache, muscular aches and toothache. In the two single-dose studies, patients with moderate to severe pain following wisdom tooth extraction received either Aleve® 440 mg (two 220 mg capsules), acetaminophen plus codeine phosphate 660 mg/60 mg (two 300 mg/30 mg capsules), or a placebo and were asked to rate their pain levels over eight hours. From the three-hour mark onward in both studies, patients who took Aleve® reported significantly reduced pain compared to those taking acetaminophen plus codeine. The 12-hour strength of Aleve® also gave patients more sustained pain relief per dose, as demonstrated by a longer median time to re-medication, versus patients on acetaminophen plus codeine.
The findings have important implications for young people, as past ADA research1 shows the majority of U.S. patients undergoing wisdom tooth removal are younger than 25. In a study published in Pediatrics2, high school students who use prescribed opioids are 33 percent more likely to misuse opioids later in life, and according to Drug & Alcohol Dependence3, post-dental surgery prescriptions account for as many as 100 million unused opioid pills – which may later be misused by the patient or a friend or family member.
"Oral analgesics are widely used by doctors to manage acute dental pain, and dentists can select from a variety of over-the-counter and prescription options, including opioids, nonopioids and combinations. The choice of treatment should strike a balance between the drug's benefits and risks, optimizing efficacy while minimizing safety concerns," said Eishdeep Cattry, PharmD, Bayer Consumer Health, who presented the data. "The results of these studies suggest that nonopioid analgesics like naproxen sodium, found in Aleve®, may be a suitable alternative for dentists to recommend for minor pain following wisdom tooth surgery."
The randomized, double-blind, placebo- and active-controlled studies included a total of 455 patients who underwent surgical third molar extraction. The average age of patients was 24 in Study #1 and 21 in Study #2. In Study #1, 25 to 27 percent vs. 15 to 18 percent in Study 2 rated their postoperative dental pain at baseline as severe. Analgesic response by treatment was measured by the change in patients' total pain relief (TOTPAR) scores and the change in patients' sum of pain intensity differences (SPID). TOTPAR was calculated as the time-weighted sum of values based on the hourly change in pain-relief levels from baseline. Pain relief scores were derived from a five-point categorical scale (0=None, 1=A little, 2=Some, 3=A lot, 4=Complete); higher scores indicated greater pain relief. SPID was calculated as the time-weighted sum of values based on changes in pain-intensity levels from baseline to a given timepoint. Four-point Categorical Rating Scale (CRS) scores (0=no pain, 1=mild pain, 2=moderate pain, 3=severe pain) were subtracted from baseline levels and converted into pain intensity difference (PID) scores; positive and higher PID scores indicated greater reduction in pain severity.
"Bayer is sharing this data with dentists and other dental professionals to increase their awareness of nonopioid options available that may effectively manage their patients' pain needs," said Manny Troullos, DMD, Senior Associate Director, Medical Affairs Analgesics, Bayer U.S. LLC. "These studies demonstrate that Aleve® is a safe and effective option for their patients to help with minor dental pain, and the studies reinforce Bayer's commitment to ensuring that patients and care providers have choices in managing pain."
More About the Studies
The primary efficacy endpoints were TOTPAR and SPID scores at 4 hours. Secondary efficacy endpoints included TOTPAR and SPID scores at 8 hours, peak PID, peak pain relief, time to relief onset, time to remedication, and overall medication rating for pain relief.

In both studies, fewer patients who took Aleve® experienced dizziness, sleepiness, nausea and vomiting than those on acetaminophen-codeine. The studies were sponsored by Bayer.
