Comparing methods of naloxone administration: A narrative review.

The effectiveness and safety of naloxone for the reversal of opioid toxicity are reviewed. A literature search was performed using PubMed, the Cochrane Library, CINAHL, and Medline. Clinical trials comparing either the clinical efficacy or pharmacokinetic/pharmacodynamic properties displayed by intravenous, intramuscular, intranasal, subcutaneous, and nebulized naloxone were included; however, trials with primary endpoints evaluating oral or endotracheal naloxone were excluded.
