Naloxone is a life-saving medication that can reverse the effects of an opioid overdose. Naloxone works by binding to the same receptors in the brain that opioids attach to, specifically the mu-opioid receptors. Opioids, such as heroin or prescription painkillers, activate these receptors, which can slow or stop breathing, leading to overdose. Naloxone acts as an opioid antagonist, meaning it blocks these receptors, reversing the life-threatening effects of the overdose.
By displacing opioids from the receptors, naloxone can quickly restore normal breathing, often within minutes. However, its effects are temporary, so it’s important to seek emergency medical help right after administering naloxone, as the effects of opioids may outlast those of naloxone.
