Description: Befetupitant, also known as Ro 67-5930, is a potent and selective NK1 receptor antagonist. Befetupitant is potentially useful in controlling chemotherapy-induced nausea and vomiting . Substance P-neurokinin-1 (NK1) receptor pathways have been repeatedly implicated in the pathophysiology of affective disorders. A high expression of NK1 receptors in brain regions that are important for the regulation of affective behaviours and stress responses.
