Cilazapril is a new once-daily angiotensin-converting (ACE) enzyme inhibitor which has been administered to 4,500 patients with mainly mild to moderate essential hypertension in a multinational clinical research program. Sitting diastolic blood pressure was reduced by about 9 mm Hg from baseline (p less than 0.01) after 4 weeks of treatment with cilazapril 1.25-10 mg/day in double-blind placebo-controlled studies. Total responder rates to cilazapril were usually 50-60% compared with 30% to placebo. Adding hydrochlorothiazide 12.5 mg/day to cilazapril 5.0 mg/day increased the total responder rate from 52 to 71%. Double-blind dose titration studies for 8 weeks showed that cilazapril 2.5-5 mg/day possessed equivalent efficacy to usual therapeutic regimens of sustained release propranolol, captopril, hydrochlorothiazide, atenolol and enalapril, Cilazapril did not affect heart rate. During long-term open administration for 52 weeks, or longer, cilazapril, either alone or in combination with hydrochlorothiazide, effectively maintained control of blood pressure. Treatment of patients with severe hypertension with cilazapril plus hydrochlorothiazide achieved a total responder rate of 73%. Adverse events were mostly observed within the first 8-16 weeks of treatment, with headache, dizziness, fatigue, nausea, cough and chest pain being the most frequent. Non-life-threatening angioedema, facial edema and mild hypotension occurred in less than or equal to 0.2% of patients, and orthostatic hypotension was reported in 2%. Abnormal laboratory test values were rarely found with cilazapril treatment. Of the 2.3% of patients with elevated serum creatinine, at any time point during the study and irrespective of outcome on continuation with cilazapril therapy, about two thirds had prior renal impairment.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of cilazapril, a new inhibitor of angiotensin-converting enzyme, in a dosage of 2.5 or 5 mg once daily, was compared with that of hydrochlorothiazide 25 or 50 mg in 169 patients with mild to moderate hypertension. Blood pressure at entry was 158/103 mm Hg (cilazapril) and 160/103 mm Hg (hydrochlorothiazide). Cilazapril 2.5 mg caused a decrease in blood pressure of 14.7 +/- 2.3/12.6 +/- 1.2 mm Hg compared with a decrease of 12.6 +/- 2.2/10.2 +/- 1.2 mm Hg with hydrochlorothiazide 25 mg. Those patients who required an increase of dosage to the higher level then showed decreases of 15.0 +/- 2.1/14.3 +/- 1.2 (cilazapril) and 19.7 +/- 1.9/13.3 +/- 1.2 hydrochlorothiazide. All decreases in blood pressure were statistically significant but were not statistically different from each other. Fifty-one percent of patients reached a sitting diastolic blood pressure of 90 mm Hg or less receiving 2.5 mg of cilazapril and an additional 28 percent of patients reached this goal receiving 5 mg. The figures for patients receiving hydrochlorothiazide were comparable: 36 and 35 percent. Twenty-one adverse events remotely, possibly, or probably related to therapy were reported with cilazapril and 32 with hydrochlorothiazide. Three patients withdrew from cilazapril because of mild angioedema, headaches, and chest pain, respectively, and three patients withdrew from hydrochlorothiazide treatment because of fatigue, dizziness, and gastric hemorrhage. Hydrochlorothiazide caused a decrease in potassium levels and an increase in levels of cholesterol, uric acid, urea and - gamma cilazapril had no adverse biochemical effects. Cilazapril lowered blood pressure to the same extent as hydrochlorothiazide. Young patients had better responses to cilazapril than to hydrochlorothiazide. It is concluded that cilazapril is an effective and safe drug for patients with mild to moderate hypertension.

Cilazapril is a structurally new angiotensin-converting enzyme inhibitor that lacks a sulfhydryl moiety. Its duration of action is consistent with a once-daily regimen. Cilazapril was studied in multiple-dose trials that included more than 4,500 hypertensive patients worldwide. Approximately 450 patients received cilazapril as monotherapy for more than one year, and another 430 patients were treated with cilazapril in combination with hydrochlorothiazide for more than six months. Cilazapril at doses of 2.5 to 5 mg once daily is clinically and statistically significantly more effective than placebo and as effective after eight weeks of therapy as hydrochlorothiazide, atenolol, propranolol sustained release, captopril, and enalapril at the doses recommended by the manufacturers. The overall incidence of adverse events observed during cilazapril therapy is comparable with that seen with placebo in double-blind studies. Cilazapril 2.5 to 5 mg once daily seems to be better tolerated than hydrochlorothiazide and atenolol. Only five adverse events were reported at an incidence of 1 percent or more in controlled trials; these were headache, dizziness, fatigue, nausea, and chest pain, which all occurred at a frequency similar to that with placebo. Overall, cilazapril is effective and well-tolerated in the treatment of patients with hypertension.

The efficacy and safety of cilazapril in chronic heart failure have been extensively investigated in an international clinical program in patients with underlying chronic heart failure with ischemic heart disease or dilated cardiomyopathy. Cilazapril in single doses of 1.25-5 mg produced a significant dose-dependent reduction in pulmonary capillary wedge pressure and systemic vascular resistance and a significant increase in cardiac index. In placebo-controlled studies, 1-5 mg of cilazapril once daily for 12 weeks prolonged predose exercise test duration and improved New York Heart Association classification status and signs and symptoms of chronic heart failure, including paroxysmal nocturnal dyspnea. Up to 86% of patients receiving these dosages had improvement, with only 12% of patients requiring the higher dose, 5 mg. These data indicate that cilazapril is effective when administered once daily to patients with chronic heart failure receiving concomitant therapy with digitalis and/or a diuretic. The safety of cilazapril in patients with chronic heart failure has been evaluated in 1,163 patients administered from 0.5 to 15 mg once daily for treatment periods ranging from 1 day to 57 months. Cilazapril was administered to 500 patients for at least 6 months, 264 patients for at least 1 year, and 101 patients for at least 2 years. The most frequently occurring adverse events were dizziness, coughing, dyspnea, fatigue, angina pectoris, and headache. Cilazapril was equally well tolerated by young and elderly patients. Treatment was discontinued due to adverse events in 12.9% of patients, mainly as a result of coughing (1.7%) and dizziness (1%). Forty-four patients (3.8%) died during cilazapril therapy or during a period without treatment. Of these deaths, 93% were due to cardiac causes, especially rhythm disturbances.(ABSTRACT TRUNCATED AT 250 WORDS)
