Ibuprofen and Acetaminophen Combo As Effective as Opioid Analgesia for Acute Pain

The opioid epidemic is the preeminent public health crisis facing the US today. In recent days, the CDC has reported that opioid overdose deaths rose by 17% in 2016, and the annual rate of fatal overdose deaths now stands at 20 per 100,000 people.1

While multiple factors have been implicated in driving the epidemic, prescription of short-term opioids for acute pain is an important risk factor for long-term opioid use.2 Opioid prescribing has grown dramatically, and over 30% of ED visits are estimated to lead to some prescription of opioid analgesia.3 Several recent studies have indicated a link between more intensive opioid prescribing practices among emergency physicians and increased risk of subsequent opioid dependence.4 Given these data, more judicious prescription of opioids is an obvious strategy to try to prevent the development of opioid dependence. Furthermore, increased use of non-opioid analgesia, particularly for short-term pain, should be emphasized.

The Study

In this context, Chang et al. conducted an ED-based randomized, double-blinded study, comparing the efficacy of a single dose of opioid- and non-opioid-based analgesia in patients presenting with moderate to severe acute extremity pain.5 Four hundred and sixteen patients were enrolled and were randomized to one of four treatment arms: 400 mg of ibuprofen and 1000 mg of acetaminophen; 5 mg of oxycodone and 325 mg of acetaminophen; 5 mg of hydrocodone and 300 mg of acetaminophen; or 30 mg of codeine and 300 mg of acetaminophen. All patients received identical capsules containing the study-drug combinations, and had pain scored at baseline, 1 and 2 hours after receiving analgesia. The primary outcome was pain score (rated at 0 to 10; where 0 is no pain and 10 is the worst pain imaginable) at 2 hours after receiving the study medication.

The Results

Enrolled patients were in moderate to severe pain, with a baseline pain score of 8.7. Pain declined in all groups over time and at 2 hours, there was a 4.3 point decline in pain score in the ibuprofen and acetaminophen treated group, with similar declines seen across the opioid arms. Mean pain scores at 2 hours were no different between any of the treatment groups, indicating the combination of acetaminophen and ibuprofen was as effective as any of the opioid combinations in this setting.5

Indications

In terms of limitations, this was a relatively small, ED-based study with very short follow-up. More data on the efficacy of this combination versus opioids over 1-2 days of pain would be informative. No data on adverse effects was collected, but the authors quote prior data suggesting that these would have been more common in opioid-treated patients.

As physicians, one of our primary instincts is to relieve pain and suffering. However, the opioid epidemic necessitates a rethink in our approach to pain management. This study suggests that pain, at least in the acute setting, can be similarly well-controlled with non-opioid alternatives,5 potentially reducing the exposure of large groups of patients to opioids, and their attendant risks.
