Analysis of adverse effects among patients with essential hypertension receiving an ACE inhibitor or a beta-blocker

Abstract

Evaluation of safety and efficacy of new drugs is based largely on data from clinical trials involving a limited number of patients. This approach does not necessarily detect the rare adverse events that may only be observed when very large numbers of patients are studied. Consequently, we designed a double-blind 12-week trial comparing the new angiotensin-converting enzyme (ACE) inhibitor, quinapril (n = 5,053), with a well-established beta-adrenergic receptor blocker, metoprolol (n = 506). Essentially hypertensive patients (diastolic blood pressure 95-114 mm Hg) received either 10 mg quinapril or 50 mg metoprolol once daily, and the doses were doubled at 4-week intervals to a maximum of 40 and 200 mg, respectively, in nonresponders. Responder rates were similar under both regimens. Adverse events were assessed by interview as well as by a standard questionnaire. The overall prevalence of adverse events reported by standard questionnaire was higher than that reported spontaneously during interviews. With respect to typical ACE inhibitor adverse reactions (e.g. cough and taste disturbances), there was no difference between quinapril and metoprolol independent of the mode of reporting. In summary, both drugs showed comparable ov...Continue Reading

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
