NK1 receptor antagonist

An NK1 receptor antagonist is a type of medication that blocks a specific receptor in the brain and nervous system called the NK1 receptor. This receptor interacts with a chemical called substance P, which is involved in transmitting pain signals, controlling nausea, and regulating mood. By blocking these receptors, the medication helps reduce nausea and vomiting, especially related to chemotherapy or surgery. It may also have effects on mood and anxiety. These drugs are an important part of treatments aimed at managing nausea and improving patient comfort.
