Enalapril in hypertension and congestive heart failure. Overall review of efficacy and safety.
|
| Abstract |
Multiclinic controlled studies have shown that enalapril alone 10 to 40 mg/day orally is effective in lowering blood pressure in patients with essential hypertension. Enalapril has been compared with thiazides and beta-blockers (propranolol, metoprolol and atenolol). The effect on systolic blood pressure has been greater with enalapril than with beta-blockers. The proportion of patients who respond to enalapril alone with a decrease in diastolic blood pressure (greater than or equal to 10mm Hg) is around 70%. When a thiazide is added to the treatment, the proportion is above 90%. Enalapril improves the signs and symptoms associated with congestive heart failure. Patients increased their exercise tolerance by an average of 148 sec and improved in their NYHA cardiac status and prognosis classification. The overall incidence of side effects is similar to that seen in the placebo control groups. Side effects such as agranulocytosis, taste loss, rash, proteinuria were not characteristic of enalapril. This supports the hypothesis that the improved safety profile of enalapril is the result of being a nonsulphydryl angiotensin-converting enzyme (ACE) inhibitor. The most common side effects reported were dizziness, headache and asthenia. Abnormalities in electrolytes, uric acid, glucose or in lipids have generally not been associated with enalapril.
