Naltrexone: The Medication for Addiction and Alcoholism
What is Naltrexone?
Naltrexone is an opioid antagonist used to treat opioid and alcohol dependence. It blocks the effects of opioids and reducing the desire to drink alcohol. Naltrexone is often part of a comprehensive addiction treatment plan, which may include counseling and other medications.
How Naltrexone Works
Naltrexone binds to the opioid receptors in the brain without activating them. This prevents the feeling of euphoria or “high” that opioids cause. It also reduces alcohol cravings by affecting dopamine release in the brain, which causes pleasure and addiction.
