ObjectivesOpioid/acetaminophen combinations may be overly prescribed in many post-surgical situations where a non-steroidal anti-inflammatory drug with equal or greater efficacy, fewer central nervous system side effects, and no risk for opioid abuse could be substituted. We compared a single, non-prescription dose of naproxen sodium 440 mg (NapS) against hydrocodone plus acetaminophen 10/650 mg (HYD+APAP) in post-impaction surgery pain.MethodsSingle-center, randomized, double-blind, placebo-controlled study in moderate-severe pain after surgical removal of impacted third molars (ClinicalTrials.gov: NCT04307940). Patients (n = 212) received NapS, HYD+APAP, or placebo and were assessed over 12 hours. Primary endpoint: summed pain intensity difference from 0 to 12 hours (SPID0-12). Secondary endpoints: pain intensity, pain relief, time to rescue medication, duration of pain at least half gone. Others: onset of pain relief, global assessment of treatment, adverse events.ResultsAll 221 randomized patients formed the safety population and were included in the intention-to-treat sensitivity analysis. Nine patients discontinued treatment or had protocol violations, and 212 patients were included in the per-protocol, primary efficacy population. Both active treatments were significantly more effective than placebo. NapS was significantly more effective than HYD+APAP regarding SPID0-12 (p = 0.01; primary endpoint), total pain relief (0-6 and 0-12 hours; p < 0.05), time to rescue medication (p < 0.001), and duration of pain at least half gone (p < 0.001). HYD+APAP was not statistically superior to NapS for any endpoint. More adverse events were reported with HYD+APAP (n = 63) than NapS (n = 2) and placebo (n = 20), including nausea, vomiting, and dizziness.ConclusionIn moderate-to-severe postsurgical dental pain, a single dose of NapS was at least as effective as HYD+APAP in the early hours, significantly more effective at reducing pain intensity and providing greater pain relief over 12 hours, and was better tolerated. When not contraindicated, NapS should be considered a preferred alternative to opioid combinations for acute pain.
