The hydrocodone in Vicodin is a synthetic opioid, which activates the same neuroreceptors as opiate drugs such as heroin.
This combination medication is used to relieve moderate to severe pain. It contains an opioid pain reliever(hydrocodone) and a non-opioid pain reliever (acetaminophen). Hydrocodone works in the brain to change how your body feels and responds to pain.
