Opioids have NO painrelieving advantage
For years, doctors turned to opioid painkillers as a first-line treatment for chronic back pain and aches in the joints. Even as the dangers of addiction and overdoses became more clear, the drugs' pain-relieving benefits were still thought to justify their risks.
Now researchers have hard data that challenges this view.
In the first randomized clinical trial to make a head-to-head comparison between opioids and other kinds of pain medications, patients who took opioids fared no better over the long term than patients who used safer alternatives.
"There was no significant difference in pain-related function between the 2 groups over 12 months," researchers reported Tuesday in the Journal of the American Medical Assn.
By some measures, the people using non-opioid drugs such as Tylenol, ibuprofen and lidocaine experienced more pain relief than people using medications like morphine, Vicodin and oxycodone — though the differences weren't large enough to be considered statistically significant. Patients in both groups saw similar improvements in their quality of life.
The findings cast doubt on the medical community's "standard approach" of using opioids to manage chronic musculoskeletal pain, the researchers found.
"Overall, opioids did not demonstrate any advantage over nonopioid medications that could potentially outweigh their greater risk of harms," wrote the team led by Dr. Erin Krebs of the Minneapolis Veterans Affairs Health Care System's Center for Chronic Disease Outcomes Research.
Krebs and her co-authors said the impetus for their clinical trial was the escalating opioid crisis, which now claims about 115 American lives each day, according to the Centers for Disease Control and Prevention. The number of overdose deaths linked to prescription drugs like oxycodone and hydrocodone has increased by a factor of four since 1999, the CDC says.
The trial — Strategies for Prescribing Analgesics Comparative Effectiveness, or SPACE — enrolled patients who were treated by the Minneapolis VA. All of the patients had pain in their backs, hips or knees for at least six months, and that pain was bad enough to interfere with their daily activities and enjoyment of life.
A total of 240 patients were randomly assigned to either the opioid or nonopioid group. About two-thirds of them had back pain, and the rest had osteoarthritis pain in their knees and hips. The average age of these patients was 58; 87% were men and 86% were white.
All patients started with lower levels of pain medications and were able to "step up" their treatment as necessary. First-line medications for the opioid group included morphine and oxycodone; patients in the nonopioid group started out with acetaminophen and NSAIDs, a group that includes aspirin and ibuprofen.
After a year of pain treatment, the researchers saw no evidence that opioids were better than the alternatives.
Using a scale that rated pain severity from 0 to 10, patients in the opioid group reported an average score of 4.0 and patients in the nonopioid group had an average score of 3.5. Over the course of a year, 41% of those taking opioids saw at least a 30% improvement in their pain severity, as did 54% of those who weren't on opioids.Read More...
