About Substance P-Neurokinin 1 (NK1) Receptor Antagonists.

Substance P/neurokinin 1 (NK1) receptor antagonists are an established pharmacologic class of antiemetic medications that competitively bind to NK1 receptors in the central and peripheral nervous systems.

By selectively blocking endogenous substance P from activating these neuroreceptors in key brainstem emetic centers, such as the area postrema and the nucleus tractus solitarius, they inhibit signaling pathways that trigger the vomiting reflex.

Clinically, these agents are primarily indicated for the prevention of acute and delayed chemotherapy-induced nausea and vomiting associated with emetogenic cancer therapies, as well as for the prevention of postoperative nausea and vomiting.
