J. Elzey AU - J. Fudin AU - E. S. Edwards A1 - AB - INTRODUCTION: Naloxone reversal of opioid-induced respiratory depression outside of medical facilities has become more prevalent because of the escalating opioid epidemic in the USA. Take-home naloxone for treatment of opioid emergencies is now being recommended by numerous federal, state, and professional organizations. Areas covered: The scope of the opioid overdose epidemic is reviewed along with practical, clinical, regulatory, and usability considerations for take-home naloxone routes of administration currently available and associated delivery systems. Specific opioid-related factors are discussed in detail with emphasis placed on life-threatening respiratory depression and naloxone antagonism. A clinical overview, including pharmacokinetic and FDA approval information for each take-home naloxone product is discussed in detail as well as the impact of take-home naloxone in the community. Finally, given these products are to be used in a panic-stricken, life-threatening opioid emergency, an analysis of available usability data is provided with proposed directions for further study. Expert opinion: Based on the available clinical evidence, auto-injectable naloxone should be the preferred administration route for take-home naloxone treatment until additional safety, efficacy, and comparative outcomes data are available for unconventional routes of administration that unequivocally provide equal or superior results.
