Used primarily in veterinary medicine, this compound is effective in preventing and treating nausea and vomiting in dogs and cats. It works by blocking substance P, a neurotransmitter in the brain responsible for triggering vomiting, particularly in the central nervous system’s vomiting center. Commonly administered before or during motion sickness, it helps reduce travel-related vomiting and anxiety in pets. It is also used post-surgery or during illness to manage vomiting caused by various medical conditions or treatments, including chemotherapy. Its ability to cross the blood-brain barrier enhances its effectiveness as an antiemetic. The compound is available in injectable and tablet forms, allowing flexible dosing in clinical and home settings.
