neurokinin-1 (NK1) receptor antagonists

Neurokinin-1 (NK1) receptor antagonists are medications that block a specific receptor in the brain and nervous system called the NK1 receptor. This receptor is involved in triggering nausea and vomiting, especially after treatments like chemotherapy. By blocking it, these drugs help prevent or reduce nausea and vomiting, improving comfort and recovery. They are often used alongside other anti-nausea medications for better effectiveness. NK1 receptor antagonists are a valuable part of supportive care for patients undergoing treatments that cause significant nausea.
