[Microcirculatory hemodynamic effects of Urapidil (Eupressyl)]. / Effets hémodynamiques microcirculatoires de l'Urapidil (Eupressyl).

A laser Doppler measurement of the microcirculatory flow rate was performed in 10 patients with moderate arterial hypertension before the delivery of a 30 mg capsule of Urapidil and 3 hours later. A significant increase in this flow rate was evidenced, thus demonstrating the arteriolar vasodilative action of Urapidil.
