Cardinal Health has launched an Opioid Action Program, aimed at helping communities in four of the nation's hardest-hit states across Appalachia combat the opioid epidemic. Under the Opioid Action Program, the firm will provide approximately 80,000 doses of the overdose-reversing drug, Narcan, for distribution free-of-charge to first responders and law enforcement officials in Tennessee and three other states. Naloxone, sold under the brand name Narcan, is a medication used to block the effects of opioids, especially in overdose. The firm also will promote drug take-back events and provide $3 million to expand grants focused on youth prevention education, prescriber opioid awareness and, reduction efforts and community responses to the epidemic in the four Appalachian states. The firm says it will also actively look to partner with others willing to support programs that prevent drug addiction.
