Many drugs have been linked to the activation of MRGPRX2 as a side effect that causes the sensation of itchiness. <ref name="Cao"/> Among these drugs are [https://en.wikipedia.org/wiki/Morphine morphine], [https://en.wikipedia.org/wiki/Codeine codeine], and | Many drugs have been linked to the activation of MRGPRX2 as a side effect that causes the sensation of itchiness. <ref name="Cao"/> Among these drugs are [https://en.wikipedia.org/wiki/Morphine morphine], [https://en.wikipedia.org/wiki/Codeine codeine], and [https://en.wikipedia.org/wiki/Dextromethorphan dextromethorphan]. These drugs contain chemical features similar to agonist R-Zinc-3573 (see Figure 4). They contain a conserved benzene ring that stabilizes them in binding pocket one (See Figure 3). Similarly, they contain an N-dimethyl group that would allow them to form key bonds with residues Asp-184 and Glu-164. Lastly, these drugs have a similar shape and size to that of the agonist R-Zinc-3573.<ref name="Babina"> Babina, M., et al.

Currently, research is being conducted to understand how to mediate the effects of MRGPRX2. This receptor is shallow and is able to bind to a variety of drugs, and its activation results in the sensation of itching. If this problem could be solved this secondary side-effect from drugs could be avoided and could aid in patient satisfaction with medication. | Currently, research is being conducted to understand how to mediate the effects of MRGPRX2.
