The aim of this 16-week trial was to determine the safety and efficacy of a step-care regimen of ramipril, an angiotensin converting enzyme inhibitor, from the minimal active dose (2.5 mg) in patients treated for mild to moderate hypertension. The trial was conducted by 102 general practitioners in 770 patients with mild to moderate hypertension. After a response rate to a 4-week placebo therapy of 9.1%, 57.0% of patients given active treatment with ramipril responded to daily doses of 2.5 mg. Ramipril 5 mg daily was effective in 55.6% of the remaining patients. There was no apparent statistically significant difference between the treatments with ramipril 10 mg or a combination of ramipril 5 mg + Lasix 20 mg daily (44.7% and 47.4% response respectively) in a 6-week double-blind arm of the study. In total, more than 90% of patients responded to treatment with ramipril by the end of the study. The incidence of adverse events was generally low, such as headache, cough, dizziness, asthenia, cramps and nausea. The incidence of cough appeared to be related both to the dosage of ramipril given and to outbreaks of influenza syndrome. Thirty-eight patients discontinued active treatment as a result of minor events such as cough, dizziness or diarrhoea, and one case each of myalgia and papular rash. There were no significant variations in laboratory parameters during the study, especially fasting blood glucose and apolipoprotein A1 and B. The results of this study provide evidence of the safety and efficacy.(ABSTRACT TRUNCATED AT 250 WORDS)

A total of 555 hypertensive patients took part in a 2-year multicenter, open-label study to determine the efficacy, tolerance, and safety of long-term therapy with ramipril. In the beginning, all patients were to receive 5 mg of ramipril/day. The dosage was then adjusted in accordance with response to treatment and ranged from 1.25-20 mg of ramipril daily. Of these patients, 129 also received 25 mg of hydrochlorothiazide daily at some point during the trial. To evaluate whether tolerance to ramipril developed during long-term treatment, a subgroup of 202 patients was analyzed for efficacy maintenance. Prior to enrolling in the 2-year study, these patients had received ramipril monotherapy in a short-term, double-blind study and had been classified as responders, i.e., their diastolic blood pressure had been maintained at less than or equal to 90 mm Hg. At the end of 104 weeks of treatment, 45.9% of patients were on 2.5 mg of ramipril alone and 43.6% were on 5 mg of ramipril alone. Only four patients required the addition of 25 mg of hydrochlorothiazide. No clinically important changes occurred, and kidney function was well maintained. The most frequently reported adverse events excluding intercurrent illnesses were dizziness/vertigo (6%), asthenia (4%), nausea (3%), headache (2%), and abdominal pain, gastrointestinal disorder, rash, and increased cough (1% each). Ramipril was safe, effective, and well tolerated in the long-term treatment of patients with mild-to-moderate essential hypertension.

Coadministration of captopril has been shown to increase serum digoxin concentration. The effects of ramipril, a new angiotensin converting enzyme inhibitor, on serum digoxin concentration after multiple dosing were studied in 12 healthy volunteers. All subjects were receiving steady-state digoxin medication (0.5 mg daily), and ramipril (5 mg daily) was coadministered for 14 days. Serum digoxin concentration was measured repeatedly before, during and up to 1 week after ramipril coadministration at 8 a.m. (trough values) and on selected trial days at 11 a.m., 3 hours after the morning medication. Simultaneously, blood levels of ramipril and its active metabolite diacid were determined. Volunteers were followed closely for side effects and for changes in blood pressure, heart rate and electrocardiogram. Safety pharmacology included serial determination of sodium, potassium, serum glutamic oxaloacetic transaminase, creatinine and a full blood count. Mean serum digoxin concentration was not significantly influenced by ramipril coadministration with trough levels of 0.90 +/- 0.24 before, 0.93 +/- 0.38 during and 0.82 +/- 0.33 ng/ml after ramipril medication. The increase in serum digoxin concentration 3 hours after the morning dose was also not significantly affected by ramipril. Serum levels of ramipril and its diacid showed a wide range of variation. Mean serum potassium increased by 0.3 mmol/liter during ramipril coadministration with development of symptomless hyperkalemia (6.0 mmol/liter) in 1 subject. The only other side effect possibly related to ramipril was a dry cough in 1 subject. Both drugs were well tolerated. Ramipril showed no significant influence on serum digoxin levels in healthy volunteers.

A postmarketing surveillance study was undertaken to confirm the efficacy and safety of the angiotensin-converting enzyme inhibitor ramipril and to extend the findings of controlled clinical trials into real-world conditions. A total of 11,100 patients with mild-to-moderate hypertension treated by primary care physicians were enrolled in this 8-week, open-label study. Ramipril was usually initiated at a dosage of 2.5 mg once daily and titrated to achieve target blood pressure. Efficacy was assessed in 8261 patients for whom blood pressure data were recorded after the start of treatment: safety was assessed in all patients. Of patients with combined systolic and diastolic hypertension, 86.0% achieved a final diastolic blood pressure of < or = 90 mm Hg or a > or = 10 mm Hg decrease from baseline; the highest response was seen in elderly patients (87.2%), and the lowest response was seen in black patients (81.2%). Of patients with isolated systolic hypertension, 70.4% achieved a final systolic blood pressure of < or = 140 mm Hg or a > or = 20 mm Hg decrease from baseline, including 70.6% of women, 70.3% of men, and 69.1% of elderly patients; the highest response was seen in white patients (71.8%), and the lowest response was seen in black patients (64.4%). Adverse events were generally mild; cough (3.0%) was the most frequent. Once-daily ramipril was effective and well tolerated during an 8-week period in a large, diverse population of patients who had mild-to-moderate hypertension and who were treated by primary care physicians.

Cough is an important side effect of Angiotensin Converting Enzyme Inhibitor (ACEI) therapy. The incidence of cough was investigated in a prospective 8 week study in 250 hypertensive patients receiving ACEI alone or in combination with other agents. Enalapril (5-20 mg/day), Lisinopril (5-20 mg/day), Captopril (25-75 mg/day) or Ramipril (5-15 mg/day) was prescribed to patients, who were followed up at weekly visits. Cough developed in 73 of the 250 patients i.e. an incidence of 29.2%. Females had a higher incidence of cough as compared to males--37.9% versus 15.5% (p < 0.001) and there was no significant difference in the cough incidence in the various age groups. A dry, non-productive cough developed in all patients within 4 weeks of ACEI initiation. Increased nocturnal intensity of cough was reported by 79.4% patients. Cough incidence was 34.4%, 24.3% and 18.1% in patients on Enalapril, Ramipril and Lisinopril, respectively. Cough was not dose related and was not related to smoking. There was no statistically significant difference among patients on ACEI alone or in combination with beta blockers, calcium channel blockers or diuretics. Of the 18 patients with ACEI induced cough who received Indomethacin, 50 mg bid, 8 reported complete cure and cough was reduced in intensity in the remaining ten.

The Heart Outcomes Prevention Evaluation (HOPE) study demonstrated that the angiotensin-converting enzyme inhibitor, ramipril, significantly reduces mortality, myocardial infarction and stroke in high-risk cardiovascular patients, beyond the benefits from blood pressure lowering. The tolerability of ramipril 10 mg/day has been an important concern when applying these results. Following the same criteria as the HOPE study, we investigated the adverse effects profile and tolerability of 10 mg ramipril in high-risk patients at our institution. In total, 92 patients with high cardiovascular risk were eligible for this study. Initially, ramipril was prescribed 2.5 mg orally once daily, and then titrated up to 5.0, 7.5, and 10.0 mg/day at 1-month intervals. The target maintenance dose was 10 mg/day. All adverse events were recorded during at least 3 months of follow-up. After 4-6 months of the titration protocol, only 18 patients (25.3%) reached and remained on ramipril 10 mg/day; 11 (15.5%), 22 (30.9%), and 20 patients (28.2%) remained on 2.5, 5.0, and 7.5 mg/day, respectively. Twenty-one patients (22.6%) had at least one adverse event. Twelve patients (13.0%) stopped treatment because of adverse effects. A total of 23 episodes of adverse events were reported, including cough (15.1%), dizziness (6.0%), and hypotension (2.4%). Ramipril was relatively well tolerated in our study population. However, only one-quarter of our patients reached the target maintenance dose of 10 mg/day. Dry cough, dizziness, and hypotension were the major side effects. About 15% of our patients discontinued ramipril treatment, which is comparable with previous reports.

ONTARGET ("ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial") compared the angiotensin converting enzyme inhibitor ramipril (10 mg/day), the angiotensin-receptor blocker telmisartan 80 mg/day, and the combination of the two drugs in 25,620 patients with vascular disease or high-risk diabetes. After a median follow up of 56 months, no significant differences were observed between the three groups neither in the primary composite outcome (death from cardiovascular causes, myocardial infarction, stroke, or hospitalization for heart failure), nor in each of its components, total mortality and other secondary outcomes. Telmisartan was equivalent to ramipril (non inferiority criterion), but was better tolerated (less cough and angioedema). The combination of the two drugs in this population (without congestive heart failure and proteinuric nephropathy) did not bring increased benefit (no superiority), but was associated with more adverse events (hypotension, syncope and renal dysfunction). In this population, the choice of the molecule in monotherapy remains optional and the use of a dual blockade is not justified in order to have a better cardiovascular protection.

To assess the safety and tolerability of ramipril 10 mg in patients at high risk of cardiovascular (CV) events by observing the levels of blood pressure (BP) and by recording the incidence of cough in these patients, a study was conducted in a total of 1048 patients who participated in the registry. Eligible patients in this prospective, observational, longitudinal, multicentre registry included all normotensives--including treated hypertensives--with BP <140/90 mm Hg, a history of coronary aritery disease and a history of cerebrovascular disease, peripheral arterial disease or diabetes (with micro-albuminuria) or dyslipidaemia, in whom ramipril was indicated for CV risk reduction and had been prescribed by the treating physician. The primary outcome was the effect on BP at 8 weeks, and the secondary outcome was the incidence of cough at 8 weeks. Ramipril was initiated at 2.5 mg once daily (OD) for a week, followed by 5 mg OD for 3 weeks and was then increased to 10 mg OD. Data was analysed using ANOVA and Chi-square test. A total of 1,048 patients participated in this registry; 868 (82.82%) continued with the treatment till the end of the registry (ie, 8 weeks). At baseline, systolic BP was 130.10 +/- 5.38 mm Hg, while diastolic BP was 81.07 +/- 4.36 mm Hg. At 8 weeks, these values changed non-significantly to 123.41 +/- 6.33 mm Hg and 79.03 +/- 4.84 mm Hg, respectively. At week 1, 41 patients had cough, which increased non-significantly to 58 by week 8. Only 6 patients complained of severe cough at week 8, which did not lead to treatment discontinuation. Tolerability of the treatment was assessed to be 'excellent' or 'good' by 63.3% patients and 67% physicians. Treatment with ramipril 10 mg daily in patients with high risk of CV events and normal/ controlled BP produced neither a significant fall in BP nor significant adverse events in real-world clinical practice and was well tolerated.

Cardiovascular risk is subject to circadian variation, with peak morning incidence of myocardial infarction and stroke correlating with the early morning blood pressure (BP) surge (EMBPS). Ideally, antihypertensive therapy should maintain control of BP throughout the 24-h dosing cycle. In two sister studies, Prospective, Randomized Investigation of the Safety and efficacy of Micardis vs Ramipril Using ABPM (ambulatory BP monitoring) (PRISMA) I and II, BP control was compared in patients with essential hypertension (24-h mean baseline ambulatory BP approximately 148/93 mm Hg) randomized to the angiotensin receptor blocker, telmisartan (80 mg; n=802), or the angiotensin-converting enzyme inhibitor, ramipril (5 or 10 mg; n=811), both dosed in the morning. The primary end point was the change from baseline in mean ambulatory systolic BP (SBP) and diastolic BP (DBP) during the final 6 h of the 24-h dosing cycle. The adjusted mean treatment differences in the last 6-h mean ambulatory SBP/DBP were -5.8/-4.2 mm Hg after 8 weeks and -4.1/-3.0 mm Hg after 14 weeks, in favour of telmisartan (P<0.0001 for all four comparisons). Secondary end point results, including the mean 24-h ambulatory BP monitoring, day- and night-time BP and 24-h BP load, also significantly favoured telmisartan (P<0.0001). Both treatments were well tolerated; adverse events, including cough, were less common with telmisartan. These findings suggest that telmisartan is more effective than ramipril throughout the 24-h period and during the EMBPS; this may be attributable to telmisartan's long duration of effect, which is sustained throughout the 24-h dosing period.

The Heart Outcomes Prevention Evaluation study established the angiotensin-converting enzyme inhibitor ramipril, versus placebo, for prevention of cardiovascular events in high-risk patients. The ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) was later conducted in similar high-risk patients using multifactorial treatment to control hypertension, platelet aggregation, and dyslipidemia, while comparing ramipril, telmisartan, or their combination, without placebo. In ONTARGET, the first angiotensin II receptor blocker-based study to be performed in a broader population of patients without congestive heart failure and/or left ventricular hypertrophy/dysfunction, telmisartan provided cardiovascular protection that was noninferior to ramipril. However, greater blockade of the renin-angiotensin system, using their combination, was not superior to ramipril alone. Telmisartan was better tolerated than ramipril in this high-risk population: notably, the incidence of cough and angioedema was significantly lower with telmisartan alone. Thus, telmisartan provides comparable efficacy to ramipril with less adverse events, which may encourage patient compliance.
