Summary
Overdose with potential deadly outcome is a serious problem among opioid abusers, not least
in Norway. The annual death toll from overdose is about 250, higher than road traffic
accidents. Those who inject heroin or other opioids are considered to have the highest risk
for death from overdose. To save lives, immediate treatment with a μ-opioid antidote such as
naloxone is required. Usually naloxone is injected into a muscle or a blood vessel.
Administration of naloxone via the nose (intranasal) has been suggested as an alternative for
use by emergency teams and possibly also bystanders. This is not only an easier way to give
naloxone, but would also eliminate the risk for needle stick injuries and blood
contamination. In a series of studies on intranasal naloxone at The Norwegian University of
Science and Technology, this study explores pharmacokinetics and pharmacodynamics of
intranasal and intramuscular naloxone in healthy volunteers under the influence of
remifentanil.
