Urapidil Hydrochloride CAS# 34661-75-1

Urapidil is a sympathetic antihypertensive drug. It acts as α 1 – adrenoceptor antagonists and 5-HT 1A receptor agonists act. Although the initial report showed that urapidil was also a α 2 – adrenoceptor agonist, which was not confirmed in later studies, proved that it had no agonist effect in the saphenous vein of dogs and ileum of guinea pigs. With others α Unlike 1-adrenoceptor villains, urapidil does not cause response tachycardia, which may be connected to its weak β 1-adrenoceptor antagonist activity and its impact on heart vagal drive. Urapidil has actually not been approved by the US Food and drug administration, yet it is offered in Europe.
