Suppressive effects of benidipine on the development of hypertension and renal lesions in salt-loaded stroke-prone spontaneously hypertensive rats.

1. The effects of benidipine hydrochloride (benidipine), a long-acting dihydropyridine calcium antagonist, on the development of hypertension and renal lesions were examined in stroke-prone spontaneously hypertensive rats (SHRSP). 2. SHRSP were fed with 8% NaCl diet for 3 weeks from 13 weeks of age, and benidipine (1 or 3 mg/kg per day) was orally administered during the same period. 3. The high salt diet accelerated an increase in urinary excretions of total protein and albumin, and caused marked arteriole, glomerular and tubular lesions in the kidney. 4. Benidipine significantly inhibited these changes, and also suppressed the elevation of blood pressure in salt-loaded SHRSP. 5. These results reveal that benidipine has protective effects against the development of hypertension and the progression of renal lesions induced by the high salt diet in SHRSP.
