[Angiotensin receptor blockers--significance for the therapy of hypertension].

Angiotensin receptor antagonists (ARB) are equally effective but better tolerated than all the other blood pressure lowering agents. The reason, why they are not subscribed as first line drugs for uncomplicated hypertension, is the higher price for these products. What the real difference in costs is, remains unclear because calculations are missing to what extent lesser controls of therapy would shift the balance in favour of the ARBs. For other indications than hypertension, but often associated with that condition, be it per se or as a consequence of it, the effects of the ARBs are studied in large trials these days. For some of them the benefit, which has been proven for ACE inhibitors, is not yet established for the ARBs, but evidence emerges that they are also useful in the treatment of cardiac failure, left ventricular hypertrophy and diabetic and other kinds of nephropathy. A large percentage of hypertensive patients can be treated effectively with ARBs without considerable side effects, thus increasing adherence and minimizing the necessity of safety controls.
