Opioid drugs include partial agonists, like the anti-diarrhea drug loperamide and antagonists like naloxegol for opioid-induced constipation, which do not cross the blood–brain barrier, but can displace other opioids from binding to those receptors in the myenteric plexus.
Opiates with opioid activity are mainly used for pain management with the premise that there will be benefits for both pain & function that will outweigh the risks to the patient. [25] Another indication is symptomatic relief of shortage of breath, both in the acute setting (for example, pulmonary edema) and in terminally ill patients. [26] [27]

While other opioids of recreational use produce only morphine, heroin also leaves 6-MAM, also a psycho-active metabolite.
Fentanyl is a highly potent synthetic piperidine opioid primarily used as an analgesic.It is 30 to 50 times more potent than heroin and 100 times more potent than morphine; [11] its primary clinical utility is in pain management for cancer patients and those recovering from painful surgeries.
The opioid receptor (OR) family originated from two duplication events of a single ancestral opioid receptor early in vertebrate evolution. Phylogenetic analysis demonstrates that the family of opioid receptors was already present at the origin of jawed vertebrates over 450 million years ago.
