Preserving Target-organ Function with Candesartan Cilexetil in Patients with Hypertension

Epidemiological evidence suggests that reducing blood pressure alone in hypertensive patients delays the onset of cardiovascular events without necessarily preventing the progression of chronic target-organ disease, such as end-stage renal failure and heart failure. Successful clinical management of hypertensive patients will therefore not be possible unless therapies are aimed both at the effective control of blood pressure and at the preservation of target-organ function. The new angiotensin II type 1 (AT 1 ) receptor blocker candesartan cilexetil has been shown to be effective in reducing target-organ damage in animal models of hypertension, even at doses that do not produce significant reductions in blood pressure. Protective effects of candesartan cilexetil towards the heart and kidney have also been demonstrated in the clinical studies that have been conducted to date. Thus, candesartan cilexetil has been shown to induce regression of left ventricular hypertrophy within 8-12 weeks of treatment and to improve renal haemodynamics, both acutely and after 6 weeks of treatment in hypertensive patients. Furthermore, in hypertensive patients with co-existent non-insulin-dependent diabetes mellitus and microalbuminuria, 12 weeks of treatment with candesartan cilexetil, 8-16 mg, significantly reduced urinary albumin excretion. Clinical evidence is therefore accumulating that the antihypertensive efficacy and tolerability profile already established for candesartan cilexetil is combined with the renal and cardioprotective effects necessary for optimal management of hypertension.
