Eliapixant

**Semantic type:** Pharmacologic Substance

**Definition:** An orally bioavailable antagonist of the purinergic receptor P2X ligand-gated ion channel 3 (P2RX3), which may potentially be used to suppress pain and chronic cough. Upon oral administration, eliapixant selectively binds to and inhibits P2RX3 expressed on sensory nerve fibers. This may inhibit P2RX3-mediated afferent nerve fiber signaling including respiratory tract afferent nerve fiber signaling, and result in the suppression of pain and chronic cough. P2RX3 plays an important role in the cough reflex. It is also a natural mediator of pain and neurogenic inflammation.
