Urapidil HCl is an antagonist of α1-adrenergic receptors (α1-ARs) and a partial agonist of the serotonin (5-HT) receptor subtype 5-HT1A. Urapidil HCl inhibits cAMP accumulation induced by forskolin. It is also a β1-AR antagonist that inhibits the positive chronotropic response induced by isoproterenol. Urapidil HCl lowers mean arterial pressure (MAP) in anesthetized cats, an effect that is reduced by central administration of the 5-HT1A receptor antagonist spiroxatrine.
