When captopril was first introduced, it was used in high doses for severe hypertension, often in the presence of renal insufficiency, and side effects such as proteinuria, rash, neutropenia, and altered taste sensation were noted. Upon analysis, these effects were most commonly seen in patients with renal disease, autoimmune disease, or collagen vascular disease. These complications usually reversed rapidly upon discontinuation of treatment. In contrast, the growing use of the angiotensin converting enzyme inhibitors, captopril and enalapril, for treating mild to moderate hypertension and the trend toward the use of lower doses has shown these agents to be well tolerated with a low frequency of troublesome adverse effects. In fact, the original spectrum of adverse effects has virtually disappeared with the use of lower doses in patients with uncomplicated hypertension. In low doses, the converting enzyme inhibitors produce remarkably few incidences of symptomatic discomfort; the most common is skin rash, which often responds to dosage reduction. Cough and rare occurrences of angioedema have also been reported. Moreover, evidence is evolving that indicates that the converting enzyme inhibitors may sometimes decrease proteinuria and improve renal function; these effects may be especially important in diabetic hypertensive patients. Of note, these drugs can also attenuate the unwanted metabolic side effects of concurrent diuretic treatment.

A total of 4676 patients and 1759 patients were treated with lisinopril and nifedipine respectively in a post-marketing surveillance study conducted in general practice in the UK. Patients were followed up for 12 months. Most of the lisinopril patients had hypertension, but a small number (180) had heart failure. Most of the nifedipine patients had uncomplicated hypertension, but some (22.57%) had other cardiovascular disease with or without hypertension. Lisinopril and nifedipine were equally effective in reducing blood pressure. During the study, 1.5% of hypertensive patients assigned to lisinopril died compared with 1.8% of patients assigned to nifedipine, and 15.1% of lisinopril patients compared with 19.7% of patients in the nifedipine group withdrew because of adverse events. Cough, malaise and fatigue, nausea and vomiting were more frequent causes of withdrawal from lisinopril than nifedipine. Conversely, headaches, pallor and flushing, oedema and palpitations caused more frequent withdrawals from nifedipine. Anaemia was more often encountered on nifedipine treatment than on lisinopril. In hypertensive patients, the frequency of first-dose hypotension was similar on both treatments. Serious events occurred in 0.8% and 0.5% of patients given lisinopril and nifedipine respectively. Lisinopril was well tolerated by heart failure patients: 16 patients (8.88%) died and an incidence of 4.44% of serious adverse events was reported, a pattern to be anticipated in such patients; dizziness, giddiness, dyspnoea, cough, nausea and vomiting were the most frequent causes of withdrawal; the incidence of first-dose hypotension was low (2.22%).(ABSTRACT TRUNCATED AT 250 WORDS)

The sixth report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-VI) includes recommendations for the assessment of overall cardiovascular risk and the need for active antihypertensive drug therapy. Once the decision to initiate antihypertensive drug therapy has been made, JNC-VI recommends one of three paths for the choice of initial therapy: one path for patients with uncomplicated hypertension, another for those with well-defined indications for certain drugs and a third path for patients with various concomitant conditions in which one or another drug has favorable effects. At this time, the place for the newest class of antihypertensive drugs, the angiotensin II receptor antagonists, remains uncertain. Currently, they are considered reasonable alternatives for patients who have a compelling need for an angiotensin-converting enzyme (ACE) inhibitor but develop a cough while taking this medication. When data from ongoing trials become available, angiotensin II receptor antagonists may prove to be a good choice for initial therapy in many patients because of the favorable side effect profile of this class of drugs.
