| In Vitro | Emedastine inhibits histamine H2 receptor (Ki=49067 nM) and histamine H3 receptor (Ki=12430 nM)[1]. High concentrations of Emedastine (1 and 10 ng/ml) significantly inhibits type 1 collagen production in normal human dermal fibroblasts[2]. Emedastine (1, 10, 100, 1000 nM) at concentrations of ≥ 10 nM inhibits CC chemokine-elicited eosinophil migration[2]. |
| In Vivo | Emedastine (0.03, 0.1, 0.3 mg/kg; orally; pretreatment of 30 min) significantly suppresses histamine-induced scratching with 0.1 and 0.3 mg/kg but not 0.03 mg/kg[3]. Pretreatment with Emedastine (0.03, 0.1, 0.3 mg/kg; orally) significantly inhibits the scratching induced by substance P and leukotriene B[3]. Emedastine (0.3 mg/kg, p.o.) produces significant inhibition of passive peritoneal anaphylaxis in guinea-pigs[2]. Emedastine inhibits histamine-induced contractions of isolated ileum (IC50=6.1 nM)[2]. Animal Model: Male ICR mice 5-6 weeks of age[3] Dosage: 0.03, 0.1, 0.3 mg/kg Administration: Orally; 30 min before pruritogen injection Result: Significantly suppressed histamine-induced scratching with pretreatment of 0.1 and 0.3 mg/kg. |
