| In Vitro | Fexofenadine (1-100 µM; 1 h) inhibits the expression of IL-6 protein in nasal fibroblasts in a dose-dependent manner[2]. Fexofenadine (1-100 µM; 1 h) blocks phosphorylated p38 activation in histamine-induced nasal fibroblasts, but shows no effect on either pERK or pJNK[2]. Western Blot Analysis[2] Cell Line: Nasal fibroblasts Concentration: 100 μM Incubation Time: 1 hour Result: Blocked pp38 activation in histamine-induced nasal fibroblasts, showed histamine-induced IL-6 production mediated by the p38 pathway. |
| In Vivo | Fexofenadine hydrochloride (oral administration; 5-20 mg/kg; once daily; 3 w) suppresses both eosinophilia and systemic anaphylaxis in C57BL/6 mice infected with T. spiralis[1]. Animal Model: C57BL/6 mice infected with Trichinella spiralis[1] Dosage: 5, 10 and 20 mg/kg Administration: Oral administration; 5, 10 and 20 mg/kg; once daily; 3 weeks Result: Inhibited eosinophilia in a dose-dependent manner. Suppressed the decrease in rectal temperature (p<0.01), a marker for systemic anaphylaxis. |
