์์ฉ ๊ธฐ์ : Grapiprant is a highly selective **EP4 receptor antagonist**. Arachidonic acid โ COX enzymes โ PGE2 โ binds to **EP4 receptors** (mediating pain/inflammation). By blocking the EP4 receptor, grapiprant inhibits PGE2-mediated vasodilation, vascular permeability, and sensory nerve sensitization without disrupting the synthesis of PGE2 or other prostanoids.
