Your doctor may also give naloxone to treat an overdose.

An opioid might activate the orphan receptor, but it might also activate other receptors that it interacts with. Imagine trying to recreate a musical score by listening to an orchestra perform a piece of music. Understanding what triggers the itching response could help pharmacologists develop an antagonist for this receptor to reduce the itching side effect. In other cases, clinicians may want to induce histamine release, thereby boosting the immune response, as in the case of vaccine adjuvants, where an increased immune response may improve immunity.

These findings suggest there may be a way to do that selectively. The researchers will now move onto other orphans. She also emphasized that work like this would not be possible without the cooperation of a wide variety specialists.

And all of these specialists working together makes findings like these possible. Note: Content may be edited for style and length. Science News. ScienceDaily, 27 March University of North Carolina Health Care.

How do some opioids cause severe itching? One of the very peculiar, interesting side effects is itching. Opioid-induced itching while suppressing pain sensation has been one of the mysteries for a long, long time. We found that this isoform is specifically required for relaying morphine-induced itch. Very interestingly and unexpectedly, we found that this isoform is not involved in morphine analgesia. So this, actually, is the first evidence to show that a morphine isoform has nothing to do with morphine analgesia.
