Brief summary
The main purpose of this study is to simulate if oxycodone and naltrexone combination capsules (ALO-02) were to be tampered with by dissolving and then injecting intravenously for the purpose of getting high.
Interventions
0.9% sodium chloride for injection x 1 dose administered intravenously (IV) push over 4 min.
Oxycodone hydrochloride (HCl) 20 mg IV and naltrexone HCl 2.4 mg IV administered simultaneously x 1 dose IV push over 4 min.
Oxycodone HCl 20 mg for injection x 1 dose IV push over 4 min.
