An opioid antagonist is a drug that binds itself to receptors in the brain and blocks the ability of the brain to respond to opiate use. Some drugs used are partial antagonists, while others provide full antagonist effects. An opioid antagonist is often used to combat addiction to opiates.
Opioids are substances that act on opioid receptors to produce morphine-like effects. Opioids are most often used medically to relieve pain. Opioids include opiates, an older term that refers to such drugs derived from opium, including morphine itself. Other opioids are semi-synthetic and synthetic drugs such as hydrocodone, oxycodone and fentanyl; antagonist drugs such as naloxone and endogenous peptides such as the endorphins.
