Naltrexone pellet implants offer a long-acting, extended-release form of naltrexone, a medication used to treat opioid and alcohol addiction. Instead of daily pills, a healthcare professional surgically inserts small pellets under the skin, typically in the buttocks. These pellets slowly release naltrexone into the bloodstream over several months, providing consistent medication levels.
How Long Does the Naltrexone Release Last?
The duration of naltrexone release depends on the pellet size and the individual’s metabolism. Common implant durations are three to six months. You’ll need follow-up appointments with your doctor to manage your treatment and potentially receive another implant.
Mechanism of Action: Blocking Opioid Receptors
Naltrexone works by blocking opioid receptors in the brain. This prevents opioids from producing their euphoric effects, reducing cravings and the risk of relapse. For alcohol dependence, the mechanism is more complex but involves reducing the rewarding effects of alcohol.
