How does Emend work?
Aprepitant, the active ingredient in Emend, is a neurokinin-1 (NK1) receptor antagonist [3]. It works by blocking the action of substance P, a natural substance in the body that plays a role in vomiting [3]. Substance P binds to NK1 receptors in the brain, triggering the vomiting reflex [3]. By blocking these receptors, aprepitant helps to prevent nausea and vomiting [3].
