Drug Overdose, Opioid-Related Disorders

Brief summary

To determine the pharmacokinetics of 4 intranasal doses of naloxone compared to a 0.4 mg dose of naloxone administrated intramuscular and to identify an appropriate intranasal dose that could achieve systemic exposure comparable to an approved parenteral dose. To also determine the pharmacokinetics of two different concentrations of intranasal naloxone and finally, to determine the safety of intranasal naloxone with respect to nasal irritation.
