Full Opiate Agonist

Drugs that activate receptors in the brain are termed agonists. Agonists occupy receptors and switch them on. As a result, they produce an effect in the brain and body. Therefore, opioid agonists switch on one or more opioid receptors.

Full Agonists stimulate activity at opioid receptors in the brain that are normally stimulated by naturally occurring opioids. Examples of full opioid agonists include morphine, methadone, oxycodone, hydrocodone, heroin, codeine, meperidine, propoxyphene, and fentanyl.
