Clinical trial in Australia tests effectiveness of naloxone by nose vs. injection for opioid overdose

JAMA Network Open

What The Study Did: A randomized clinical trial in Australia tested whether a dose of naloxone administered through the nose was as effective as the same dose delivered by injection to reverse opioid overdose as measured by the need for a rescue dose delivered by injection 10 minutes after the initial treatment. The study included 197 clients at a medically supervised injecting center in Sydney where eligible patients (18 or older with a history of injecting drug use) are allowed to inject drugs under the supervision of clinically trained staff who watch for signs of overdose.
