AP PSYCHOLOGY

Detailed explanation-1: -An agonist is something that causes a specific physiological response in the cell. They can be natural or artificial. For instance, endorphins are natural agonists of opioid receptors. But morphine – or heroin that turns into morphine in the body – is an artificial agonist of the main opioid receptor.

Detailed explanation-2: -Naltrexone, an Antagonist for the Treatment of Heroin Dependence Effects in Man.

Detailed explanation-3: -An agonist is a drug that activates certain receptors in the brain. Full agonist opioids activate the opioid receptors in the brain fully resulting in the full opioid effect. Examples of full agonists are heroin, oxycodone, methadone, hydrocodone, morphine, opium and others.

Detailed explanation-4: -They soon figured out that the active ingredient in all these opiates-morphine-had a chemical structure similar to endorphins, a class of chemicals present in the brain . Endorphins are feel-good chemicals naturally-manufactured in the brain when the body experiences pain or stress.

Detailed explanation-5: -Suboxone, Methadone, and Naltrexone Specifically, Suboxone is a combination of buprenorphine, an opioid medication and partial agonist, and naloxone, also a narcotic and antagonist, which works to reverse the effects of other drugs. Suboxone is an agonist and opioid blocker.
