In studies funded by the federal government, Opvee achieved similar recovery results to Narcan, the leading brand of naloxone nasal spray.
Both work by blocking the effects of opioids in the brain, which can restore normal breathing and blood pressure in people who have recently overdosed.
Opvee was developed by Opiant Pharmaceuticals, which was recently acquired by rival Indivior, maker of several medications for opioid addiction. Indivior expects to launch Opvee in October at the earliest. Scientists at the National Institutes of Health worked with pharmaceutical researchers on a nasal spray version of nalmefene that would quickly resuscitate users, while also protecting them from relapse. Testing and development was funded by more than $18 million in grants from the U.S. government’s Biomedical Advanced Research and Development Authority and the NIH, which also helped design the studies.
“The risk of long-lasting withdrawal is very real and we try to avoid it,” said Nelson, an emergency medicine physician and former adviser to the FDA on opioids.“We’re not suffering from a naloxone shortage where we need to use an alternative,” he said. “We have plenty of it and it works perfectly well.”
