PALOXIRON 0.5MG is a medication containing the active ingredient Palonosetron, an antiemetic used to prevent nausea and vomiting, particularly in patients undergoing chemotherapy or other treatments like radiation therapy. At a dosage of 0.5 milligrams (MG), Palonosetron works by blocking serotonin receptors (specifically the 5-HT3 receptors) in the brain and gastrointestinal tract, which are responsible for triggering the vomiting reflex. It is typically administered intravenously in a healthcare setting, where it helps to provide effective and long-lasting protection against chemotherapy-induced nausea and vomiting (CINV). PALOXIRON is known for its prolonged action, with a longer half-life than many other antiemetics, allowing for a single dose to provide extended relief. Like all medications, it should be used according to a healthcare provider's instructions, and potential side effects or interactions with other drugs should be monitored.
