They exert their therapeutic effect primarily by competitively antagonizing or acting as inverse agonists at histamine H1 receptors, thereby suppressing histamine-driven vasodilation, vascular permeability, and sensory nerve activation Clinically, these agents are utilized to manage localized allergic inflammation and pruritus, most notably in allergic conjunctivitis, allergic rhinitis, and pruritic dermatoses such as insect bites, contact dermatitis, and eczema

Clinically, these agents are utilized to manage localized allergic inflammation and pruritus, most notably in allergic conjunctivitis, allergic rhinitis, and pruritic dermatoses such as insect bites, contact dermatitis, and eczema
