Naloxone (also known as Narcan, the commonly used drug to treat narcotic overdoses) has greater binding to opioid receptors ...

Naloxone, which is given as a nasal spray or injection, works by seizing opioid receptors, kicking out opioids and taking their place. (Naloxone has no addictive properties of its own.) The ...

However, the action of naloxone only lasts about 2 hours before it detaches from the receptor, allowing longer-lasting opioid molecules, such as fentanyl, which can remain in the bloodstream for 8 ...

The drug, dubbed compound 368, makes naloxone (Narcan) 7.6 times more effective at inhibiting the opioid response that causes overdose, researchers report in the July 3 issue of the journal Nature.

Naloxone, commonly known by the brand name Narcan, is an opioid-receptor blocker that can reverse opioid overdoses. This easy ...

However, it is only able to occupy pain receptors for 30 to 90 minutes. For more potent opioids, such as fentanyl, that may not be long enough. To determine how the naloxone companion drug, which ...

Naloxone (orange) treats opioid overdose by kicking out opioids (pink) from the opioid receptor (teal). The newly discovered compound 368 (purple) strengthens the binding of naloxone to the opioid ...

To do so, they screened a library of 4.5 billion molecules in the lab in search of molecules that bound to the opioid receptor with naloxone already tucked into the receptor's pocket. Compounds ...

NOTES: (1) Naloxone is less effective in saving people who have overdosed on fentanyl because fentanyl binds more tightly than heroin to opioid receptors in the brain, so it is more difficult for ...

Naloxone works by binding to opioid receptors in the brain and essentially blocks and reverses the effects of other opioids. The medication allows for the body’s response system to switch back ...

Naloxone, however, does not significantly affect alpha-2 receptors, so it doesn’t work as well with opioids laced with animal tranquilizers.

Naloxone is a safe, easy-to-use, life-saving medication that blocks the effects of opioids. Naloxone is an opioid receptor antagonist that can be given through injection or nasal spray.
