What is another name for Narcan? Understanding Naloxone and Other Opioid Reversal Drugs

4 min read

According to the CDC, over 80,400 people in the U.S. died from opioid-involved overdoses in 2021. In the face of this public health crisis, a critical tool in reversing these overdoses is Narcan, which leads many to wonder what is another name for Narcan and how does it actually function?

Quick Summary

Narcan is a widely recognized brand name for the generic, life-saving medication naloxone. As a fast-acting opioid antagonist, it reverses the effects of an overdose, primarily respiratory depression. Other brands exist, including Kloxxado and Zimhi, and administration can be done by non-medical personnel.

Key Points

  • Generic vs. Brand Name: Naloxone is the generic name for the opioid overdose reversal medication, with Narcan being the most widely known brand name.

  • Mechanism of Action: Naloxone works by acting as an opioid antagonist, attaching to opioid receptors in the brain to reverse and block the effects of other opioids.

  • Rapid Reversal: Administered via nasal spray or injection, naloxone can quickly restore normal breathing in a person whose breathing has slowed or stopped due to an opioid overdose.

  • Expanded Access: Once a prescription-only medication used primarily by first responders, naloxone is now available over-the-counter and through community distribution programs.

  • Temporary Effect: Naloxone's effects last for 30–90 minutes. Because opioids can remain in the system longer, repeat doses and immediate medical follow-up are critical to prevent re-overdose.

  • Safety Profile: The medication is safe to use and will not cause harm to a person who does not have opioids in their system. In opioid-dependent individuals, it can induce withdrawal symptoms.

  • Legal Protection: Good Samaritan laws in many states protect individuals who administer naloxone in an emergency from civil or criminal liability.

The Generic Name: Naloxone

Narcan is a brand name for the drug naloxone hydrochloride. The active ingredient in Narcan, and other similar products, is naloxone. Naloxone is an opioid antagonist that works by attaching to opioid receptors in the brain, blocking the effects of other opioids and reversing life-threatening respiratory depression. It is safe to administer to someone without opioids in their system.

Other Common Brand Names and Formulations

Beyond Narcan, naloxone is available under other brand names and in different forms:

Common naloxone formulations include:

  • Intranasal Spray: Brands like Narcan (4mg) and Kloxxado (8mg) are prepackaged, needle-free sprays for one nostril.
  • Auto-injector: Zimhi is a pre-filled device that injects into the thigh muscle.
  • Standard Injectable: Administered via syringe, typically in medical settings but also in some community kits.

The History and Expansion of Access

Approved by the FDA in 1971, naloxone was initially limited to hospitals and EMS. Starting in the late 1990s, community programs advocated for wider access, recognizing that most overdoses are witnessed by non-medical individuals. The first such program was in Chicago in 1996. This led to widespread support, Good Samaritan laws offering legal protection for administrators, and eventually, FDA approval for over-the-counter naloxone nasal spray in March 2023.

Administering Naloxone in an Emergency

Recognizing overdose signs and knowing how to use naloxone is crucial. Overdose signs include:

  • Unconsciousness or unresponsiveness.
  • Slow or shallow breathing.
  • Pinpoint pupils.
  • Pale or bluish skin, lips, or nails.
  • Gurgling or choking sounds.

In the event of an overdose:

  1. Call 911 immediately. Report unresponsiveness and abnormal breathing.
  2. Administer Naloxone. Use nasal spray in one nostril or follow instructions for other forms. It takes 2–3 minutes to take effect.
  3. Provide Rescue Breathing. If the person is not breathing, perform rescue breaths.
  4. Repeat Dose if Needed. Naloxone's effects last 30–90 minutes; opioids can last longer. Give a second dose after 2–3 minutes if there's no response or relapse.
  5. Place in Recovery Position. If leaving the person, turn them on their side to prevent choking.

Naloxone vs. Narcan and Other Brands: A Comparison

Active Ingredient Naloxone Hydrochloride Naloxone Hydrochloride Naloxone Hydrochloride Naloxone Hydrochloride
Delivery Method Varies (Injection, Nasal) Prepackaged Nasal Spray Prepackaged Nasal Spray Pre-filled Injection
Standard Dosage Varies by formulation 4 mg per spray 8 mg per spray 5 mg/0.5mL injection
Primary Setting Emergency medical services; community kits Community use; easy for laypersons Responding to potent opioids like fentanyl Community use; autoinjector for muscle injection
Availability Available as prescription and OTC OTC Prescription only Prescription only
Use Case Reverses opioid overdose Reverses opioid overdose; standard first response Reverses opioid overdose, especially potent ones Reverses opioid overdose; auto-injector ease of use

Key Safety Considerations

  • Safe for bystanders: Naloxone is safe for anyone, and it will not cause harm to a person who does not have opioids in their system.
  • Not a substitute for medical care: The person still needs immediate medical attention, as the effects of naloxone wear off, and the opioid can cause breathing to stop again.
  • Withdrawal symptoms: In an opioid-dependent person, naloxone can trigger acute and unpleasant, but not fatal, withdrawal symptoms.
  • Limited side effects: Allergic reactions are possible but rare. Otherwise, side effects are minimal.

Conclusion

In conclusion, the most common other name for Narcan is its generic form, naloxone. This opioid antagonist is a crucial tool in the battle against overdose deaths, rapidly reversing respiratory depression caused by opioids. With the availability of both brand-name products like Narcan and higher-dose options such as Kloxxado, as well as the convenience of over-the-counter access, more people can be equipped to respond to an opioid overdose. Ultimately, recognizing and understanding the relationship between Narcan and naloxone is not just a matter of pharmaceutical knowledge but a vital step towards public health education and saving lives.
