Aprepitant

aprepitant

Aprepitant is an oral medicine used to prevent nausea and vomiting, most often for people receiving chemotherapy or after surgery. It works by blocking substance P from activating neurokinin-1 (NK1) receptors in the brain, which helps stop the signals that cause nausea and vomiting. Because it acts on a different pathway than other anti-nausea drugs, it is commonly given together with steroid drugs and serotonin-blocking medicines for better protection. Aprepitant has a long duration of action, so a short course of pills can cover both the early and delayed phases of chemotherapy-related nausea. This protection helps patients maintain nutrition, avoid dehydration, and complete their treatment plans. Common side effects are usually mild and include tiredness, constipation, and occasional hiccups, though liver enzyme changes or other effects can occur in some people. Aprepitant can change how the liver processes other medicines, so doctors will review all current medications, including birth control pills, because interactions can reduce their effectiveness. Beyond its main use for nausea, it is being studied for possible roles in treating certain pain and inflammatory conditions. In short, aprepitant is a key tool for preventing severe nausea and improving quality of life during and after medical treatments.
