A new study published by the scientific journal Addiction has found that a concentrated 2mg intranasal naloxone spray delivers naloxone as effectively, over the critical first 15 minutes, as the standard 0.4mg intramuscular (IM) naloxone injection. The research was co-authored by Professor Sir John Strang and Dr Rebecca McDonald, National Addiction Centre, Institute of Psychiatry, Psychology & Neuroscience (IoPPN), King’s College London.

Too many Americans die of overdoses that could be prevented by a combination of policy shifts and education. New efforts to fight overdose—like a recently announced Obama administration initiative—are underway. But surprisingly, for a condition that is so common and so deadly, some key details remain widely unknown—details that could be life-saving in the right hands. If we want to prevent overdose, we need to gather and distribute this information to those who need it most.
