Biochem/physiol Actions

Rupatadine (UR-12592) is an orally active, dual histamine H1 and platelet-activating factor (PAF) receptor antagonist (Ki(app) = 100/550 nM against pyrilamine/WEB2086 binding to guinea pig cerebellum/rabbit platelet membranes) that inhibits histamine-induced guinea pig ileum contraction (pA2 = 9.29) and PAF-induced platelet aggregation (IC50 = 0.68 μM/human PRP). Rupatadine blocks histamine-/PAF-induced hypotension (ID50 = 1.4/0.44 mg/kg i.v. rats) and bronchoconstriction (ID50 = 113/9.6 μg/kg i.v. guinea pigs), as well as prevents mortality caused by PAF (ID50 = 0.31 mg/kg i.v. or 3.0 mg/kg p.o. mice) and endotoxin (mice/rats ID50 = 1.6/0.66 mg/kg i.v.) in vivo.

A similar immune response is implicated in the pathogenesis of pulmonary fibrosis and allergic disorders. We investigated the potential therapeutic efficacy and mechanism of rupatadine, a dual antagonist of histamine and platelet-activation factor (PAF), in bleomycin- (BLM-) and silica-induced pulmonary
