Brand names: NEREUS
12.1 Mechanism of Action Tradipitant is a selective, high-affinity antagonist of human substance P/neurokinin 1 (NK1) receptors. Tradipitant does not have affinity for NK2 and NK3 receptors, serotonin (5-HT3), dopamine (D2), cholinergic, or histamine (H1) receptors. Tradipitant has been shown in animal models to inhibit drug induced emesis. Human Positron Emission Tomography (PET) studies with tradipitant have shown that tradipitant crosses the blood brain barrier and occupies brain NK-1 receptors. The exact mechanism by which tradipitant exerts its therapeutic effect is not fully established.
