Opioids may be a little help for chronic pain
In a study published today by the Journal of the American Medical Association (JAMA), McMaster University researchers reviewed 96 clinical trials with more than 26,000 participants and found opioids provide only small improvements in pain, physical functioning and sleep quality compared to a placebo.
The opioids, however, also increase the risk of vomiting, drowsiness, constipation, dizziness, nausea, dry mouth, and itching.
The researchers’ analysis also found low to moderate quality evidence showing similar benefits for pain and physical functioning between opioids and non-opioid alternatives such as nonsteroidal anti-inflammatories, antidepressants, and synthetic cannabinoids.
The study is important as there are an estimated 50 million Americans and six million Canadians living with chronic non-cancer pain, many who are prescribed opioid medications.
“Despite widespread use, there is not enough known about the benefits and harms of opioids for chronic non-cancer pain,” said Jason Busse, lead author of the study and a researcher with the Michael G. DeGroote Institute for Pain Research and Care at McMaster University.
