title: Calcium channel blockers in the prevention of end stage renal disease: a review.
abstract: Hypertension and high levels of proteinuria are independent risk factors for accelerated progression of renal failure. There is increasing evidence that strict control of both blood pressure (BP) and proteinuria are beneficial in slowing the rate of progression of chronic renal disease in diabetic as well as non-diabetic nephropathy. The angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin 2 receptor blockers (ARB) have clearly demonstrated their beneficial effect on both reduction of BP and proteinuria. The calcium channel blockers (CCB) have individual pharmacological and therapeutic properties that may vary, but as a group they are effective antihypertensive agents in patients with renal disease. Their effects on the kidney may extend beyond BP reduction alone. Current studies suggest that CCB do not worsen the progression of renal disease but may rather provide benefit when systemic BP has been tightly normalised. The non-dihydropyridine calcium channel blockers (NDHP), diltiazem and verapamil, slow the progression of type 2 diabetic nephropathy with overt proteinuria almost to a similar extent as observed with ACE-I. The dihydropyridine calcium channel blockers (DHP) have a variable effect on proteinuria. Pharmaceutical compounds, which inhibit the renin-angiotensin system (RAAS), remain the drugs of first choice in the treatment of hypertension and/or proteinuria in chronic nephropathy. However, a combination of two or more drugs is almost always required to attain sufficient BP reduction. CCB may have an advantage in combination with ACE-I and/or ARB.
