The effect of pravastatin on renal function and lipid metabolism in patients with renal dysfunction with hypertension and hyperlipidemia. Pravastatin and Renal Function Research Group.

The effect of pravastatin on renal function in hypertensive patients with mild renal dysfunction and hyperlipidemia was examined. A total of 57 subjects given dihydropyridine calcium blockers were randomly assigned to placebo (n = 25) and pravastatin groups (n = 32). The period of study was 6 months. In the placebo group, lipid metabolism did not change throughout the study period, but the serum creatinine concentration (Scr) increased from a baseline of 1.6+/-0.07 mg/dl to 2.1+/-0.2 mg/dl in the 6th month of study and blood urea nitrogen (BUN) increased from 26.2+/-1.1 mg/dl to 32.4+/-30.1 mg/dl. In the pravastatin group, the serum total cholesterol decreased from a baseline of 251.4+/-7.3 mg/dl to 218.2+/-6.5 mg/dl in the 6th month of study, while Scr (1.3+/-0.07 mg/dl vs. 1.3 +/-0.09 mg/dl) and BNU (20.5+/-1.2 mg/dl vs. 21.0+/-1.4 mg/dl) did not change. The change in Scr in the placebo group was significantly different from that in the pravastatin group (F = 3.75, p = 0.05). The slope of the change in 1/Scr was 0.02+/-0.07 dl x mg(-1) x month(-1) in placebo group and -0.01+/-0.03 dl x mg(-1) month(-1) in pravastatin group (P<0.05). The results indicate that pravastatin attenuates the deterioration of renal function in patients with mild renal dysfunction, together with an improvement of lipid metabolism.
