antiemetic agents

Antiemetic agents are medications used to prevent or treat nausea and vomiting. They work by blocking signals in the brain that trigger these symptoms, often caused by motion sickness, medications, or medical conditions. Common examples include ondansetron and metoclopramide. Antiemetics are especially important for patients undergoing chemotherapy or surgery, where nausea is a common side effect. By alleviating discomfort, these medications help improve quality of life and allow individuals to continue with their daily activities or treatment without the disruption caused by nausea.
