NARCAN® (naloxone hydrochloride) nasal spray clinical trials

Comparison of multiple doses of intramuscular versus intranasal naloxone for reversal of opioid toxicity

This study looks at how well different ways of giving naloxone work to reverse the effects of strong painkillers (opioids) in healthy volunteers. Researchers are comparing injections to a nasal spray to see which is most effective and how many doses are needed.
