Abstract:
:Lacidipine is a clinically active, antihypertensive calcium antagonist of the 1,4 dihydropyridine (DHP) class. It is also capable of vascular protection when administered (prophylactically and therapeutically) at nonsustained antihypertensive doses to salt-sensitive Dahl-S rats: useful animal models for studying the vasoprotective effect of calcium antagonists. In our previous work using voltammetry with selective biosensors, we observed that lacidipine implements endothelial nitrogen monoxide (NO) in normal rats. These experiments, performed in aortic rings obtained from Dahl-S rats analyzed with voltammetry and specific biosensors, further demonstrate that lacidipine, given at doses that do not control the development of hypertension (1 mg/kg), enhance endothelial NO activity. Taken together with the observation that 1 mg/kg lacidipine, and not its vehicle, is able to prevent vascular damage and concomitant increases in mortality (accelerated by a salt diet), this voltametric data suggest that NO acts as a component of positive influence of this DHP on vascular structure and function.
