[Cilazapril, a new ACE inhibitor, in severe arterial hypertension]

We assessed the efficacy and safety of cilazapril, alone or in combination with hydrochlorothiazide. It was an open trial, that included 14 patients with or more 114 mmHg of diastolic arterial tension. On the first stage of 25 days, the arterial tension was normalized in 5 patients with 10 mg of cilazapril and 7 patients when hydrochlorothiazide was added, 2 patients did not respond. On the second stage of 52 weeks, of the 12 patients whose diastolic arterial tension was normalized, 2 patients remained with normal arterial tension with cilazapril, 5 when hydrochlorothiazide was added and the rest 5 patients did not respond. No undesirable side effects were detected, nor abnormalities in the laboratory tests. The long-term benefit obtained on 50% of patients make evident the usefulness of cilazapril in severe arterial hypertension. Its administration once a day and the absence of side effects increase the interest of its use.
