Among patients with acute, low back pain presenting to an emergency department, neither the nonsteroidal anti-inflammatory drug (NSAID) naproxen combined with oxycodone/acetaminophen or the muscle relaxant cyclobenzaprine provided better pain relief or improvement in functional outcomes than naproxen combined with placebo, according to a study in JAMA.
Low back pain (LBP) is responsible for 2.4 percent of visits to U.S. emergency departments, resulting in more than 2.5 million visits annually. These patients are usually treated with NSAIDs, acetaminophen, opioids, or skeletal muscle relaxants, often in combination.
