In fact, buprenorphine has a higher affinity for opioid receptors than almost all opioids including heroin.

Cannabinoid receptors are 10 times more prevalent in the brain than opioid receptors.

There are also opioid receptors present, which may be involved in the mechanism by which opiates cause nausea and vomiting.

Cyprenorphine has mixed agonist-antagonist effects at opioid receptors, like those of buprenorphine.

Opioids exert their pharmacological effects by binding to opioid receptors.

These drugs bind to opioid receptors in the peripheral and central nervous systems producing analgesic effects.

That study has been widely credited as the first definitive finding of an opioid receptor, although two other studies followed shortly after.

These drugs work by blocking opioid receptors in the body's cells, and are often used to treat people with drug overdoses.

For opioid receptors, the fate of the internalized receptors is still uncertain.

In pharmacology, kappa represents a type of opioid receptor.
