Adamis Pharmaceuticals Corporation announced that the U.S. Food and Drug Administration (FDA) has approved Adamis ZIMHI (naloxone HCL Injection, USP) 5 mg/0.5 mL product. ZIMHI is a high-dose naloxone injection product FDA-approved for use in the treatment of opioid overdose. Naloxone is an opioid antagonist and is generally considered the drug of choice for immediate administration for opioid overdose. It works by blocking or reversing the effects of the opioid, including extreme drowsiness, slowed breathing, or loss of consciousness. Common opioids include morphine, heroin, tramadol, oxycodone, hydrocodone and fentanyl. According to statistics published by the Centers for Disease Control and Prevention (CDC), drug overdoses resulted in approximately 96,779 deaths in the United States during the 12-month period ending March 2021, which was a 29% increase over the prior 12-month period. Drug overdoses are now the leading cause of death for Americans under age 50, with more powerful synthetic opioids, like fentanyl and its analogues, responsible for the number of those deaths.
