Applications of Maropitant

  • Injectable maropitant is used in dogs to treat and prevent acute vomiting; tablets are used for preventing vomiting from a variety of causes, though they require a higher dose to prevent vomiting from motion sickness. The injectable version is also licensed for preventing and treating acute vomiting in cats.
  • Maropitant is effective in treating vomiting from a variety of causes, including gastroenteritis, chemotherapy, and kidney failure; when given beforehand, it can prevent vomiting caused by using an opioid as a premedication. Some have claimed that maropitant is better at treating vomiting than nausea, pointing to cats with chronic kidney disease who, when receiving maropitant, had a reduction in vomiting but no corresponding increase in appetite.
  • Maropitant has been used in acute cases of rapid or labored breathing to prevent vomiting that could lead to aspiration pneumonia. It has been given in combination with a benzodiazepine to cats prior to stressful events (such as a veterinary visit) to possibly relieve hypersensitivity.
