Pharmacokinetics
How It Works
Fosaprepitant is a prodrug that is rapidly converted to aprepitant, which is a selective high-affinity antagonist at the neurokinin-1 (NK1) receptor. By blocking the binding of substance P to NK1 receptors in the brain, it prevents the emetic signals that trigger nausea and vomiting.
