  • Title: Update on the clinical pharmacology of candesartan cilexetil.
    Author: Gavras H.
    Journal: Am J Hypertens; 2000 Jan; 13(1 Pt 2):25S-30S. PubMed ID: 10678285.
    Abstract:
    The renin-angiotensin system plays a central role in the regulation of blood pressure through its primary effector hormone angiotensin II. Studies conducted nearly 30 years ago with peptidic angiotensin II receptor blockers (ARB) suggested that disruption of the renin-angiotensin system offered considerable promise for the treatment of hypertension as well as heart failure. This promise was initially realized with the advent of angiotensin converting enzyme inhibitors, and more recently with nonpeptidic ARB that selectively antagonize the AT1-angiotensin receptor subtype. The potent and long-acting agent candesartan cilexetil illustrates how these new ARB fulfill the promises suggested by the early studies. Candesartan cilexetil provides a clinically relevant, dose-dependent reduction in diastolic and systolic blood pressure at doses of 4 to 16 mg once daily in patients with mild to moderate hypertension. Recent studies suggest that further blood pressure lowering is obtained with a 32-mg once daily dose. In comparative clinical trials, 8 mg of candesartan cilexetil and 10 to 20 mg of enalapril provided comparable antihypertensive effects. The safety and tolerability profile of candesartan cilexetil is comparable to placebo. Notably, this agent does not produce the dry, nonproductive cough that often limits use of angiotensin converting enzyme inhibitors, nor does it cause side effects that limit other antihypertensive drug classes. On the basis of the results of initial clinical studies, ARB also possess cardioprotective and renoprotective properties that promise to expand the role that these new agents will play in treating cardiovascular disorders.
