It seems you might be referring to "metoclopramide," which is a medication commonly used to treat gastrointestinal issues such as nausea, vomiting, and gastroparesis (a condition where the stomach takes too long to empty its contents). Metoclopramide works by increasing the movement in the stomach and intestines and blocking certain signals in the brain that trigger nausea and vomiting.
If you meant something else or need more specific information, please clarify!
