Comparison of Naloxone Pharmacokinetics

• Status: Completed
• Trial end date: 2018-03-06
• Target enrollment: 0
• Participant gender: All

Summary

Intranasal (IN) naloxone administration is an effective alternative to intravenous (IV) or intramuscular (IM) naloxone by emergency medical services for opioid overdoses and has been used successfully for this purpose as reported in clinical observational studies and a randomized controlled trial. Most of the published clinical studies concerning IN administration used an improvised kit of 2 mg naloxone/2 mL saline and a mucosal atomizer device (MAD), which is not FDA-approved for this indication. Pharmacokinetic (PK) data using these kits is not available in the published literature. This study is designed to determine the PK of naloxone following one and two IN administrations using the improvised kits compared to 2 and 4 mg delivered IN using the FDA-approved Narcan nasal spray device and 2 mg administered IM using the Evzio autoinjector.
