Next-generation single-dose antidotes for opioid overdoses

EurekAlert   -   Scientific News Websites

Fentanyl's powerful effects are long-lasting, and even tiny amounts of the drug can lead to an overdose. Antidotes, such as naloxone, do not last long enough in the body to fully counter the drug, requiring repeated injections. Now, scientist...
