New dihydropyridine calcium channel antagonist, pranidipine, attenuates hypertensive renal injury in Dahl salt-sensitive rats
1994
Interest in the cardiovascular protective effects of calcium channel antagonists has increased in the past decade. We investigated prevention of vascular wall remodeling by the long-acting calcium channel antagonist pranidipine in 12-week-old Dahl salt-sensitive (SS) rats with high-salt-induced (4% NaCl) hypertension. Six-week pranidipine treatment (60 mg/kg chow) decreased systolic blood pressure (SBP) by 22% in SS rats. This BP reduction was associated with decreases in cardiac mass and weight of the aortic wall. Glomerular filtration rate (GFR) was increased by 33%, but this did not lead to a decrease in urinary protein or NAG excretion
