Brief Summary

WHAT IS THE PURPOSE OF THIS RESEARCH STUDY This research study is designed to demonstrate that intramuscular (IM) Injection of FDA Approved Naloxone Hydrochloride (HCI) given in the forearm muscle is approximately the same as given the injection in the buttocks muscle. STAT Therapeutics Inc. is sponsoring this research study. BACKGOUND AND PURPOSE FOR THIS STUDY You are being asked to participate in this research study because you are between the ages of 18 and 55 and appear to be in stable health. Naloxone HCI is FDA approved and has been used to treat symptoms of opioid overdose for over 40 years. This research study is designed to demonstrate that intramuscular (IM) Injection of FDA Approved Naloxone Hydrochloride (HCI) given in the forearm is approximately the same as given the injection in the buttocks. This is the first time Naloxone Hydrochloride (HCI) is given in the forearm muscle. This is an open-label study. This means that you, the Doctor, study staff, and the Sponsor will know the study drug and the dose that you are given.
