Two advisory committees to the US Meals and Drug Administration have voted unanimously to advocate {that a} nasal spray model of the opioid overdose antidote, naloxone (additionally known as Narcan), be made out there over-the-counter.
If the FDA agrees with this suggestion, naloxone could quickly be bought and not using a prescription in pharmacies and made out there in grocery shops, big-box shops, gasoline stations, and nook shops across the nation.
This growth comes at a time when opioid overdoses are at a report excessive, rising greater than 15% in a single 12 months. Deaths attributed to opioids rose from round 70,000 in 2020 to 80,800 in 2021, based on the US Centers for Disease Control and Prevention. The extremely potent and deadly opioid, fentanyl, is implicated within the majority of those deaths.
What’s naloxone, and the way does it work to save lots of lives from opioid overdose? How have you learnt if somebody is overdosing, and the way can bystanders administer the antidote? How can individuals get entry to it now, and what’s going to it imply if the FDA approves it for over-the-counter use? What extra must be performed to cut back overdose deaths?
To information us by these questions, I spoke with CNN Medical Analyst Dr. Leana Wen, an emergency doctor and professor of well being coverage and administration on the George Washington College Milken Institute Faculty of Public Well being. She can also be the chair of the advisory board for Behavioral Health Group, a community of outpatient opioid therapy and restoration facilities round the US. Beforehand, she was Baltimore’s well being commissioner, the place she led town’s overdose prevention technique.
CNN: How does naloxone work to save lots of individuals overdosing on opioids?
Dr. Leana Wen: Naloxone is a medication that quickly reverses the impact of an opioid overdose. It’s an antagonist to opioids, which means that it attaches to the opioid receptors within the mind, and in doing so, reverses and blocks the consequences of opioids.
Somebody who has taken too giant of a amount of opioids can develop into unconscious and cease respiratory. That is lethal — an individual can die inside minutes after they cease respiratory. Naloxone reverses the impact of the opioid overdose and may restore regular respiratory inside a few minutes.
CNN: What are the totally different variations of naloxone? Does it work towards illicit medication like heroin and fentanyl in addition to pharmaceuticals?
Wen: Naloxone is available in two primary varieties. There may be the nasal spray model, with one producer calling its product Narcan Nasal Spray. This model is sprayed into the nostril, just like some allergy drugs.
Naloxone additionally comes as a liquid. This way may be injected both intravenously by an IV, if a affected person already has an IV inserted, or intramuscularly, normally as a shot by the quadriceps muscle within the leg.
A number of years in the past, there was one other model of naloxone that was in an autoinjector, just like an EpiPen that’s given to individuals with life-threatening allergic reactions. In 2019, the producer made a business decision to cease making that model out there to the general public. (An autoinjector continues to be accredited to be used by the navy and for chemical incident responders.)
The nasal spray, intravenous and intramuscular variations all work very nicely, and so they all work towards varied variations of opioids. That features not solely heroin and fentanyl but in addition frequent opioid drugs like oxycodone, hydrocodone, codeine and morphine. It’s essential to notice that one dose might not be sufficient, relying on how potent and the way a lot opioid was taken. Usually, a number of doses are wanted to revive somebody.
CNN: How have you learnt if somebody is overdosing, and the way can bystanders administer the antidote?
Wen: Indicators of overdose embody being unable to be woke up, respiratory slowly or not respiratory in any respect, and fingernails and lips taking over a blue or purple shade whereas the pores and skin turns into pale and clammy to the contact. Their pupils are sometimes described as “pinpoint,” or very small.
Somebody can overdose from taking an excessive amount of of an opioid accidentally. This typically occurs when fentanyl, an especially potent opioid, is combined with regardless of the particular person is taking with out their information. Additionally, if an opioid is combined with alcohol or benzodiazepines or different opioids, they’ll additionally develop into unresponsive. And there are cases when somebody could not notice they’re taking opioids, however the capsule they obtained is contaminated with fentanyl.
If somebody is overdosing, you or somebody who’s with you need to name 911 instantly. Within the meantime, administer naloxone. Naloxone reverses an overdose for as much as about 90 minutes, however opioids can keep within the system for longer, so it’s nonetheless essential for the particular person to obtain medical consideration after receiving the drug. Relying on the opioid the particular person took, they might must be monitored within the hospital for hours after in case naloxone wears off whereas the opioid continues to have an impact.
You probably have the nasal spray model, insert the tip of the machine into the nostril and squeeze. One other spray could also be given within the different nostril in two to 3 minutes if the affected person stays unresponsive, and one other one in one other two to 3 minutes till both the affected person responds or emergency assist arrives. If you’re skilled to carry out CPR, and the particular person isn’t respiratory, it is best to administer CPR as nicely, in between giving naloxone.
CNN: Is naloxone secure to make use of? What when you’re undecided if somebody is overdosing from opioids?
Wen: Sure, naloxone is extraordinarily secure. If somebody is just not on opioids and is unresponsive, say, as a result of they drank an excessive amount of alcohol or has had a stroke, naloxone could have no opposed impact for them. That’s why emergency medical personnel routinely administer naloxone to sufferers who’re discovered to be unresponsive; there is no such thing as a hurt to people who find themselves unresponsive from non-opioid-related causes.
If somebody overdosed on opioids, naloxone reversal will ship them into withdrawal. This might be disagreeable for the person and will result in vomiting, agitation, shivering, tearing up and having a runny nostril. These aren’t fascinating unwanted effects, in fact, however in circumstances when naloxone should be given, the choice is dying.
CNN: How can individuals get entry to naloxone now? What’s going to it imply if the FDA approves it for over-the-counter use?
Wen: As an emergency doctor, I’ve given naloxone many occasions. First responders like paramedics and emergency medical technicians additionally routinely administer naloxone. Once I served as Baltimore’s well being commissioner, I felt strongly that everybody ought to be capable to save another person’s life.
Nonmedical personnel could already acquire and carry naloxone with them, however particular necessities and rules vary by the state. Well being departments and a few group nonprofit teams have low-priced or free naloxone that they distribute to group members. Usually, the naloxone is distributed to people who use medication, as a result of they’re most probably to be round others who’re overdosing. Additionally, their relations can use naloxone to revive them.
