Urapidil is a sympatholytic antihypertensive drug. It acts as an α1-adrenoceptor antagonist and as an 5-HT1A receptor agonist[1] Although an initial report suggested that urapidil was also an α2-adrenoceptor agonist,[2] this was not substantiated in later studies that demonstrated it was devoid of agonist actions in the dog saphenous vein and the guinea-pig ileum.[3] Unlike some other α1-adrenoceptor antagonists, urapidil does not elicit reflex tachycardia, and this may be related to its weak β1-adrenoceptor antagonist activity.[4][5] as well as its effect on cardiac vagal drive [6] Urapidil is currently not approved by the U.S. Food and Drug Administration, but it is available in Europe.
