The future of calcium channel blocker therapy in diabetes mellitus.
Diabetes mellitus is associated with significant morbidity and mortality caused by the micro- and macro-vascular complications that all too frequently develop during the lifetime of the diabetic patient. In attempts to treat the complications of diabetes, several different treatment strategies have been investigated. The role of tight blood glucose control in the treatment of diabetic vascular complications has recently been challenged, as the existing data in support of this mode of therapy are currently inconclusive. Perhaps more effective in preventing many of the vascular complications is the rigorous treatment of hypertension that frequently accompanies diabetes mellitus. Epidemiological studies have demonstrated that the presence of hypertension significantly contributes to the development and progression of diabetic nephropathy, retinopathy, cardiovascular disease, and possibly neuropathy. Preliminary clinical studies demonstrate that the progression of diabetic renal disease can be slowed by vigorous antihypertensive therapy. Among the various antihypertensive agents used to treat the hypertension associated with diabetes mellitus, calcium channel blockers are emerging as one of the agents of first choice. This is because of their very low side effect profile and their absence of detrimental effects on serum lipid levels and glucose tolerance. Calcium channel blockers may be of additional potential benefit to the diabetic patient by slowing the progression of atherosclerosis, reversing the intracellular calcium defects that may contribute to the pathogenesis of diabetic cardiomyopathy, and protecting against the progression of chronic renal disease.
