Detailed explanation-1: -Opioid receptor antagonists block one or more of the opioid receptors in the central or peripheral nervous system.
Detailed explanation-2: -Some street drugs, including cocaine, methamphetamine, heroin, marijuana, nicotine, alcohol, and prescription painkillers, can alter a person’s behavior by interfering with neurotransmitters and the normal communication between brain cells.
Detailed explanation-3: -An antagonist is a drug that blocks opioids by attaching to the opioid receptors without activating them. Antagonists cause no opioid effect and block full agonist opioids. Examples are naltrexone and naloxone.
Detailed explanation-4: -Opioid agonists such as methadone or buprenorphine are therapeutic drugs used for the management of opioid dependence. In clinical practice, they are used for opioid agonist maintenance therapy or withdrawal manafement.
Detailed explanation-5: -Opioids block the neurotransmitter dopamine. Opioids bind to receptors in the peripheral and CNS to block pain signals.
