Opioids

A new study has found that exposing babies to prescription opioids while they’re in the womb can increase their risk of developing immune-related conditions – particularly infections, eczema and asthma – in early childhood.

A new study has found that there was no association between using cannabis and non-medical opioid use in people receiving pharmacotherapy for opioid use disorder. The findings neither confirm that using cannabis leads to opioid use nor that it's effective in reducing it.

Spread by sandfly bites, the leishmania parasite causes ulcers that for many people are unexpectedly pain-free. For decades scientists have been puzzled by these painless lesions but new research is now homing in on the unusual analgesic mechanisms.

Researchers are close to human clinical trials to test the safety and efficacy of vaccines to prevent heroin and fentanyl overdoses. If approved, they could revolutionize the treatment of opioid addiction and reduce deaths from overdose.

Researchers have developed an antibody that targets the opioid fentanyl and its derivatives, reversing overdose better than currently available treatments. The novel therapy could be a more effective way of treating life-threatening opioid overdoses.

Clinical trials of a novel non-opioid analgesic have found it to be effective in reducing acute postoperative pain, opening the door to a new way of managing short-term pain that avoids the pitfalls associated with using opioids.

Despite their risks, opioids are commonly prescribed as a first-line treatment for acute lower back and neck pain. Researchers have found that, compared to opioids, a placebo is more effective in reducing acute – short-term – back and neck pain.

While opioids are among the most powerful painkillers, they're also highly addictive, which makes them hard to get. A new finding may offer hope to pain patients in the form of powerful drugs that lack the most severe side effects of current options.

A new study has shown that for people with chronic pain taking opioids over the long term, incorporating an internet-based self-management program into treatment may help reduce both pain and opioid intake.

Scientists have discovered how a specific brain circuit functions during fentanyl withdrawal, potentially leading to relapse. Suppression of this could lead to better, targeted medical treatments for opioid use disorders.

Although the drug naloxone can be a lifesaver in cases of opioid overdose, it has to be administered quickly. That's where a new wearable device comes in, as it's designed to first detect the effects of an overdose, and then deliver an injection of naloxone.

Intriguing new preclinical research has found targeting opioid receptors in the gut could be a new treatment for inflammatory bowel disease. The research builds on early evidence showing a relationship between opioids and immune cell function.
