Ebastine

Research use only, not for human use.

Ebastine is a potent H1-histamine receptor antagonist, used for allergic disorders.

Ebastine is a potent H1-histamine receptor antagonist, used for allergic disorders.(In Vitro):Ebastine (10-500 ng/mL; 24-48 hours) treatment significantly increases the proliferation of HFDPC.Ebastine (10-500 ng/mL; 24-48 hours) treatment shows dose-dependent increases in Cyclin D1, Cyclin E1, and Cyclin A expression levels. And the expression levels of Cdk4, Cdk2, and Cdc2 are alos increased. Ebastine treatment elevates expression levels of phospho-AKT and phospho-p44/42 extracellular signal-regulated kinase. (In Vivo):In rats, after intravenous administration of [14C]Ebastine at 2 mg/kg, the plasma level of radioactivity decreased biphasically with α-phase half-life (t1/2 α) of 1.6 h and β-phase half-life (t1/2 β) of 3.1 h.Following oral administration of [14C]Ebastine at a dose of 2 mg/kg, the plasma level reached the maximum (Cmax) of 102 ng eq./ml at 2 h and decreased monophasically with t1/2 of 3.9 h. At 20 mg/kg, a monophasic decrease is also observed with Cmax of 1110 ng eq./ml at 4 h and with t1/2 of 4.0 h.
