Innovative Implant Offers New Hope For Opioid Crisis
Naloxone is a lifesaving medication that can reverse an opioid overdose, and it is now available over-the-counter. However, a significant drawback remains: the drug must be administered by a knowledgeable bystander via nasal spray or injection. In response to this challenge, researchers have developed an innovative implant designed to automatically deliver naloxone without requiring external assistance.
This new device, called the Naloximeter, is engineered to detect the onset of an overdose and promptly administer naloxone to the individual in distress. Additionally, it sends an emergency alert to first responders. According to Robert Gereau, director of the Washington University Pain Center, many overdose victims are alone and unable to recognize their situation. He emphasized the importance of having a device that can quickly provide assistance without the need for human intervention, thus potentially saving more lives.
Statistics show that over 70,000 individuals die each year from opioid overdoses. Naloxone functions by binding to the same brain receptors as opioids, effectively displacing them and restoring normal breathing. In studies conducted on animals, the Naloximeter was shown to successfully deliver naloxone when it detected signs of an overdose. The implant relies on a drop in oxygen levels—often a precursor to overdose—triggering its response, as overdosing on opioids typically results in slow and shallow breathing.
The Naloximeter is implanted beneath the skin and monitors the user’s oxygen levels. If these levels fall below a certain threshold, the device sends an alert to a mobile application. Should the individual fail to cancel the rescue procedure within 30 seconds, naloxone is automatically administered. In trials involving small and large animals, the implant functioned as intended, with all subjects recovering fully within five minutes after receiving naloxone.
Furthermore, the Naloximeter also calls for emergency assistance since naloxone’s effects can be temporary and the symptoms of an overdose may return. The study detailing this device was published on October 23 in the journal Science Advances. The researchers have secured a patent for the Naloximeter and are currently refining the technology while seeking partnerships in the industry. Joanna Ciatti, a graduate student at Northwestern University, noted that this proof-of-concept device could have broader applications for other medical emergencies, such as anaphylaxis or epilepsy, paving the way for future advancements in autonomous rescue technology.
