Abstract
BACKGROUND Therapeutic agents for the treatment of hypertension may differ in their efficacy during the early morning period, a time when both morbid and mortal cardiovascular events are increased compared to other times of the day. METHODS We studied the effects of a graded-release delivery system of diltiazem (diltiazem HCL extended release tablets) versus ramipril, both dosed at bedtime, on blood pressure (BP), heart rate, and the heart rate-systolic BP product during the first 4 hours after awakening in a double-blind, titration-to-effect trial. There were 261 men and women enrolled in the trial with an untreated sitting diastolic BP of 90 to 109 mm Hg and ambulatory daytime diastolic BP of 85 to 109 mm Hg. Patients were randomized to either diltiazem extended release (ER) tablets each evening (240 mg titrated to 360 mg and to 540 mg) or ramipril each evening (5 mg titrated to 10 mg and to 20 mg). Early morning assessments of BP, heart rate, and the heart rate-systolic BP product were performed using 24-hour ambulatory recordings after 10 weeks of therapy. RESULTS In each therapeutic group, 76% of patients were titrated to the highest possible dose. After 10 weeks of treatment, reductions in early morning BP by diltiazem ER tablets were significantly greater (-18/-15 mm Hg) than reductions by ramipril (-13/-8 mmHg, P <.005 for systolic BP and P <.001 for diastolic BP). Diltiazem ER tablets also led to greater reductions in morning heart rate and the heart rate-pressure product compared to ramipril. Reductions in mean 24-hour diastolic BP, heart rate, and the rate-pressure product were greater in patients treated with diltiazem ER tablets compared to ramipril, while reductions in 24-hour systolic BP were similar in each group. The observed adverse effects were not serious and incidences were similar for the 2 treatment groups. CONCLUSIONS These data demonstrate that bedtime administration of diltiazem ER, an agent designed to parallel the circadian rhythm of BP and heart rate, led to significantly greater early morning hemodynamic effects compared to the angiotensin-converting enzyme inhibitor ramipril, also dosed in the evening.

Abstract
Microalbuminuria and hypertension are risk factors for diabetic nephropathy in Type 2 diabetic patients. Recent data suggest that blockade of the renin-angiotensin system slows the progression of diabetic nephropathy; in contrast, the results on the renoprotective effect of calcium channel antagonists are conflicting. We evaluated the effectiveness of lercanidipine, in comparison with ramipril, on the reduction in albumin excretion rate (AER) and blood pressure in mild-to-moderate hypertensive patients with Type 2 diabetes and persistent microalbuminuria. A total of 277 patients were enrolled in a multicentric, randomized, double-blind, active-controlled, parallel-group trial; 180 were randomized to receive 10-20 mg/day of lercanidipine or 5-10 mg/day of ramipril and followed up for 9-12 months. The primary outcome was the change in AER from baseline. After 9-12 months of follow-up, a reduction in AER of -17.4+/-65 microg/min (p<0.05) and -19.7+/-52.5 (p<0.05) in the lercanidipine and ramipril group, respectively, was observed, without differences between the groups. A significant reduction in systolic and diastolic blood pressure was observed in both the lercanidipine and ramipril-based treatment groups (p<0.0001 for both). This study demonstrated that treatment with lercanidipine 10-20 mg/day does not worsen albuminuria in microalbuminuric Type 2 diabetic patients with hypertension. Indeed, both lercanidipine and ramipril treatments resulted in a significant reduction in AER without a statistically significant difference between the two groups.

Abstract
BACKGROUND Angioedema, particularly of the head and neck, is a well-recognized adverse effect of angiotensin-converting enzyme (ACE) inhibitors. Most cases respond to conventional therapy, including antihistamines and corticosteroids. Severe episodes may require epinephrine and intubation. OBJECTIVE To report the case of a patient with ACE inhibitor-induced angioedema treated with fresh frozen plasma (FFP). METHODS The patient is a 43-year-old, white woman who first received the ACE inhibitor ramipril in March 2002. After 3 weeks, she developed angioedema of her lips and fingers, which resolved with antihistamines, corticosteroids, and one dose of epinephrine. A low dose of ramipril was restarted 4 days later, which was increased throughout 4 days. In late August 2002, she developed severe upper lip and tongue edema recalcitrant to conventional therapy. Her C1 esterase inhibitor level was normal. RESULTS After 4 days of treatment with antihistamines, corticosteroids, epinephrine, antileukotrienes, cyclosporine, and intravenous immunoglobulins, the patient's tongue swelling continued to recur and became more severe. Two units of intravenous FFP was given, with rapid improvement and no further recurrence of tongue swelling. CONCLUSIONS In our patient, FFP was highly successful in the treatment of resistant, life-threatening angioedema due to an ACE inhibitor. The benefit of FFP in this setting might be due to the effect of kininase II in breaking down accumulated bradykinin.

Abstract
AIM The study was conducted to evaluate efficacy and tolerability of fixed dose combination (FDC) of Losartan and Ramipril in the management of mild to moderate hypertensive Native Asian Indian patients with associated diabetes mellitus. The secondary objective was to evaluate the efficacy of the combination in reducing microalbuminuria. MATERIAL AND METHODS The study was an open, non-comparative, multicentric clinical trial conducted in seven Indian centres in 315 eligible patients. All the patients were treated with Losartan 50 mg + Ramipril 2.5 mg or Losartan 50 mg + Ramipril 5 mg once a day in 12 weeks and consisted of a total of eight visits. RESULTS The mean age of patients was 52.93 years (range 45 - 60 years). Of the total patients, 62.86% were males and 37.14% were females. The mean prestudy systolic blood pressure was 160.56 +/- 14.44 which was significantly reduced to 126.85 +/- 9.78 at the end of 12 weeks (P < 0.001). Similarly the mean diastolic blood pressure was 98.91 +/- 8.33 at baseline (stage I) which was significantly reduced to 79.82 +/- 5.42 at the end of 12 weeks (P < 0.001). A mean fall of 33.72 mmHg in systolic blood pressure and the mean fall of 19.10 mmHg was observed in systolic and diastolic blood pressure respectively at the end of the treatment which was statistically highly significant (P < 0.001). The JNC-VII goal of blood pressure < 130/80 was achieved in 79.05% patients after the treatment which losartan and ramipril combination only. Microalbuminuria (urinary albumin excretion > 30 but < 300 mg/day) was seen in 83/250 (33.2%) patients and 135 (54%) patients had clinical proteinuria (albuminuria) at baseline. At the end of the therapy 20.8% patients achieved normoalbuminuria. Good to excellent efficacy response was reported in 98.09% patients and 98.41% patients reported good to excellent tolerability to the treatment. CONCLUSION The fixed dose combination of Losartan and Ramipril showed good to excellent efficacy response in 98.10% patients and achieved a target blood pressure of 130/80 mmHg in 79.05% patients in 12 weeks. The combination reduced the urinary albumin excretion in majority of the patients with microalbuminuria and proteinuria (the major marker of nephropathy).

Abstract
OBJECTIVE To investigate whether a low dose of the angiotensin converting enzyme (ACE) inhibitor ramipril lowers cardiovascular and renal events in patients with type 2 diabetes who have microalbuminuria or proteinuria. DESIGN Randomised, double blind, parallel group trial comparing ramipril (1.25 mg/day) with placebo (on top of usual treatment) for cardiovascular and renal outcomes for at least three years. SETTING Multicentre, primary care study conducted mostly by general practitioners in 16 European and north African countries. PARTICIPANTS 4912 patients with type 2 diabetes aged >50 years who use oral antidiabetic drugs and have persistent microalbuminuria or proteinuria (urinary albumin excretion > or = 20 mg/l in two consecutive samples), and serum creatinine < or = 150 micromol/l. MAIN OUTCOME MEASURES The primary outcome measure was the combined incidence of cardiovascular death, non-fatal myocardial infarction, stroke, heart failure leading to hospital admission, and end stage renal failure. RESULTS Participants were followed for 3 to 6 (median 4) years. There were 362 primary events among the 2443 participants taking ramipril (37.8 per 1000 patient years) and 377 events among the 2469 participants taking placebo (38.8 per 1000 patient years; hazard ratio 1.03 (95% confidence interval 0.89 to 1.20, P = 0.65)). None of the components of the primary outcome was reduced. Ramipril lowered systolic and diastolic blood pressures (by 2.43 and 1.06 mm Hg respectively after two years) and favoured regression from microalbuminuria (20-200 mg/l) or proteinuria (> 200mg/l) to normal level (< 20 mg/l) or microalbuminuria (P < 0.07) in 1868 participants who completed the study. CONCLUSIONS Low dose (1.25 mg) ramipril once daily has no effect on cardiovascular and renal outcomes of patients with type 2 diabetes and albuminuria, despite a slight decrease in blood pressure and urinary albumin. The cardiovascular benefits of a daily higher dose (10 mg) ramipril observed elsewhere are not found with an eightfold lower daily dose.

Abstract
UNLABELLED Ramipril (Altace)Use of tradenames is for product identification purposes only and does not imply endorsement.), an angiotensin-converting enzyme (ACE) inhibitor, is a prodrug which is rapidly hydrolyzed after absorption to the active metabolite ramiprilat. Earlier trials have shown that ACE inhibitors, when given to patients with low ejection fractions, have reduced the relative risk of myocardial infarction (MI) and other ischemic events by 14-23%. Subsequently, the double-blind, randomized, placebo-controlled, multicenter Heart Outcomes Prevention Evaluation (HOPE) study has shown that, in patients who are not known to have low ejection fraction or heart failure but are at increased risk for developing cardiovascular events, ramipril reduced the incidence of stroke, MI and death due to cardiovascular disease. Results from the HOPE study, in which 9297 patients were randomized to receive either ramipril 10 mg/day or placebo for a mean of 4.5 years, indicate that ramipril reduced the relative risk of the composite outcome of MI, stroke and cardiovascular death by 22%. The incidence of the composite outcome was significantly lower in the ramipril group than in the placebo group (14.0% vs 17.8%). Patients who received ramipril, compared with placebo recipients, had a significantly decreased incidence of stroke, MI or death due to cardiovascular disease (3.4% vs 4.9%, 9.9% vs 12.3% and 6.1% vs 8.1%, respectively). The relative risk of death from any cause was reduced among patients who received ramipril. In addition, treatment with ramipril reduced as the incidence of revascularization procedures, and, among patients with diabetes mellitus, ramipril reduced the incidence of complications related to diabetes mellitus, including the development of overt nephropathy. Moreover, in patients without a previous diagnosis of diabetes mellitus, ramipril, compared with placebo, significantly reduced the development of diabetes mellitus. Furthermore, compared with patients receiving placebo, patients receiving ramipril had a reduced rate of progression of carotid artery wall thickness. CONCLUSION Ramipril 10 mg/day can significantly reduce the incidence of MI, stroke or death from cardiovascular causes in patients aged > or =55 years who are at increased risk for the development of ischemic cardiovascular events due to a history of stroke, coronary artery disease (with controlled blood pressure), diabetes mellitus plus at least one other risk factor or peripheral vascular disease but no heart failure or low ejection fraction. Therefore, in addition to dietary and lifestyle modifications, ramipril should be an integral part of secondary prevention therapy in patients at increased risk for the development of cardiovascular events.

Abstract
A 61-year-old patient who had been treated with lisinopril in the past without any problems was commenced on ramipril for left ventricular dysfunction. He developed a painful symmetrical purpuric eruption over both feet after three days. A full vasculitis screen was negative. Ramipril was stopped and he required a course of steroids after which the rash improved slowly. The ACE inhibitors can cause various skin side effects; however, it rarely causes cutaneous vasculitis. Ramipril-induced cutaneous vasculitis is particularly rare and our case was atypical because the patient had tolerated lisinopril before. Previous successful treatment with one ACE inhibitor does not rule out the vasculitis caused by the drug from the same group. Here we report ramipril-induced cutaneous vasculitis in a patient who required steroid therapy to control it.

Abstract
BACKGROUND Patients on chronic hemodialysis often suffer from severe anemia, the outcome of iron deficiency and inadequate response to erythropoietin. Antihypertensive treatment with captopril worsens anemia, erythropoietin production and iron balance in hemodialysis patients. We investigated the possibility that iron chelation by captopril in the blood may result in elimination of iron-captopril complexes during hemodialysis, thus minimizing the effect of both medications. METHODS Twelve hypertensive hemodialysis patients (group 1) were treated with 12.5 mg/day captopril, while their 12 counterparts received 1.25 mg/day ramipril. Following two weeks of treatment and two weeks of "washout", captopril in group 1 was substituted with ramipril and ramipril in group 2 was replaced by captopril for an additional two week period. Blood and dialysate samples were procured at the beginning and the end of the dialysis, for iron, aluminum, transferin, ferritin, hemoglobin (Hb) and hematocrit (Htc) determination. RESULTS Iron, ferritin, transferin, Hb and Htc were decreased in the captopril-treated group 1. They similarly decreased in group 2 following replacement of ramipril by captopril for an additional period of two weeks. Significant amounts of iron were detected in dialysates of captopril, but not ramipril-treated patients. At the end of the dialysis, iron content was further increased in dialysates of the captopril-treated groups. CONCLUSIONS 1) Captopril-chelated iron is eliminated in dialysis fluid during the dialysis session, apparently contributing to captopril-related anemia in patients on chronic hemodialysis. 2) Antihypertensive treatment with angiotensin converting enzyme (ACE) inhibitors other than captopril might prove advantageous for this patient category.

Abstract
CONTEXT Angiotensin-converting enzyme inhibitors are prescribed for many cardiovascular and renal diseases. Adverse hepatic events, especially cholestasis, have rarely been reported with captopril, enalapril, lisinopril, and fosinopril. To date, hepatic injury associated with ramipril has not been reported. OBJECTIVE To describe 3 patients who developed hepatitis, with or without jaundice, after receiving ramipril. DESIGN Medical records and liver biopsies of the 3 patients were reviewed. Clinical, laboratory, and histologic findings were compared with findings in other cases of angiotensin-converting enzyme inhibitor-induced liver injury reported in the literature. RESULTS The 3 patients were middle-aged men. In 2 patients, jaundice appeared 4 and 8 weeks after starting ramipril. Bilirubin levels peaked at 15.5 and 5 mg/dL, and alkaline phosphatase values peaked at 957 and 507 U/L. Aminotransferase levels were mildly elevated. Endoscopic retrograde cholangiopancreatography and ultrasonography showed no bile duct obstruction. Liver biopsies from the jaundiced patients were similar, with cholestasis, duct necrosis, and extravasation of bile, ductular proliferation, and portal inflammation. Cholestasis improved in 1 patient 6 weeks after stopping ramipril and was prolonged for 14 months in the other, in whom biliary cirrhosis was present on biopsy. The third patient developed hepatitis without jaundice 3 weeks after starting ramipril; symptoms resolved after stopping the drug. Ramipril-associated liver injury is similar to that seen with other angiotensin-converting enzyme inhibitors, but liver biopsy findings of duct necrosis and extravasation of bile have not been reported previously. CONCLUSION Prolonged cholestatic hepatitis and biliary cirrhosis may result from the use of ramipril. Monitoring of liver enzymes is advisable for patients starting on ramipril.

Abstract
BACKGROUND Residual renal function is an important determinant of mortality and morbidity in patients receiving peritoneal dialysis. However, few studies have evaluated therapeutic approaches for preserving residual renal function after the initiation of dialysis. OBJECTIVE To test the hypothesis that the angiotensin-converting enzyme (ACE) inhibitor ramipril slows the decline in residual renal function in patients with end-stage renal failure treated with peritoneal dialysis. DESIGN Randomized, open-label, controlled trial. SETTING Single-center study in the dialysis unit of a university teaching hospital. PATIENTS 60 patients receiving peritoneal dialysis. MEASUREMENTS Patients were randomly assigned to ramipril (5 mg daily) or no treatment. The target blood pressure was 135/85 mm Hg or less. Rate of decline in residual glomerular filtration rate (GFR) and development of complete anuria were compared among groups. RESULTS Over 12 months, average residual GFR declined by 2.07 mL/min per 1.73 m2 in the ramipril group versus 3.00 mL/min per 1.73 m2 in the control group (P = 0.03). The difference between the average changes in residual GFR in the ramipril and control groups from baseline to 12 months was 0.93 mL/min per 1.73 m2 (95% CI, 0.09 to 1.78 mL/min per 1.73 m2). At 12 months, 14 patients in the ramipril group and 22 in the control group developed anuria. With intention-to-treat multivariable analysis using the Cox model, it was estimated that at 3, 6, and 9 months, patients assigned to ramipril had a higher adjusted hazard of complete anuria than did patients assigned to no treatment. Of the 25 patients who still did not have complete anuria at 12 months, those assigned to ramipril had a better prognosis than did those assigned to no treatment (adjusted hazard ratio, 0.58 [CI, 0.36 to 0.94]). The rates of death from any cause, duration of hospitalization, and cardiovascular events did not differ significantly between groups. CONCLUSIONS Although the trial was small and had a limited ability to exclude effects of potential confounding factors, the angiotensin-converting enzyme inhibitor ramipril may reduce the rate of decline of residual renal function in patients with end-stage renal failure treated with peritoneal dialysis.

Abstract
BACKGROUND By inhibiting prostaglandin synthesis, aspirin can interfere with both arterial functional and angiotensin-converting enzyme inhibitor (ACEI) properties and be deleterious in chronic heart failure (CHF). AIM Our aim was to prospectively evaluate the effect of aspirin on arterial functional properties in CHF patients treated with ACEIs. METHODS AND RESULTS Over three consecutive treatment periods of 7 days, 18 patients received placebo, followed by aspirin 100 mg/day, and then aspirin 325 mg/day. Single blind prospective assessment of reflected wave and time reflection by radial applanation tonometry; pulse wave velocity; blood pressure; thromboxane B2 (TxB2) and prostaglandins in plasma and urine was performed. Aspirin 325 mg/day induced a significant increase in augmentation index of reflected wave (P<0.0001 and P=0.0013 vs. placebo and aspirin 100 mg, respectively) and a significant decrease in reflected wave traveling times (P=0.0007 vs. placebo). Aspirin 100 mg/day produced a similar, though non-significant, trend in these parameters compared with placebo. Both aspirin treatments produced a statistically significant decrease in serum TxB2 (P<0.0001) but did not have an effect on the metabolite of prostaglandin I2 (P=0.136). CONCLUSION This study demonstrates the existence of a dose-mediated deleterious effect of aspirin upon arterial functional properties in CHF patients treated with ACEI.

Abstract
The final results of the African American Study of Kidney Disease and Hypertension (AASK) have shown that the angiotensin-converting enzyme inhibitor ramipril was better than the beta blocker metoprolol or the dihydropyridine calcium channel blocker amlodipine in slowing the rate of glomerular filtration rate decline in African American patients with mild to moderate renal insufficiency. Of note, there was no difference between the 92 mm Hg or less (lower group) and the 102-107 mm Hg (usual) mean arterial pressure groups as regards the secondary clinical composite end point. The secondary clinical composite end point in this study comprised a threshold drop of at least 50% or 25 mL/min in glomerular filtration rate, death, or reaching end-stage renal disease. The final results from this study would suggest that reduction in blood pressure to levels below those currently advocated for cardiovascular risk reduction, although a clearly attainable goal in this population, does not provide readily identifiable benefits to African Americans with hypertensive nephrosclerosis. Importantly, this study provides the basis for the primary use of angiotensin-converting enzyme inhibitors in an African American population with the characteristics of those studied in AASK. It remains to be determined if this represents a class effect for all angiotensin-converting enzyme inhibitors.

Abstract
UNLABELLED Ramipril, an angiotensin-converting enzyme (ACE) inhibitor, is a prodrug which is rapidly hydrolysed after absorption to the active metabolite ramiprilat. Earlier trials have shown that ACE inhibitors, when given to patients with low ejection fractions, have reduced the relative risk of myocardial infarction (MI) and other ischaemic events by 14 to 23%. Subsequently, the double-blind, randomised, placebo-controlled, multicentre Heart Outcomes Prevention Evaluation (HOPE) study has shown that, in patients who are not known to have low ejection fraction or heart failure but are at increased risk for developing cardiovascular events, ramipril reduced the incidence of stroke, MI and death due to cardiovascular disease. Results from the HOPE study, in which 9297 patients were randomised to receive either ramipril 10 mg/day or placebo for a mean of 4.5 years, indicate that ramipril reduced the relative risk of the composite outcome of MI, stroke and cardiovascular death by 22%. The incidence of the composite outcome was significantly lower in the ramipril group than in the placebo group (14.0 vs 17.8%). Patients who received ramipril, compared with placebo recipients, had a significantly decreased incidence of stroke, MI or death due to cardiovascular disease (3.4 vs 4.9%, 9.9 vs 12.3% and 6.1 vs 8.1%, respectively). The relative risk of death from any cause was reduced among patients who received ramipril. In addition, treatment with ramipril reduced as the incidence of revascularisation procedures, and, among patients with diabetes mellitus, ramipril reduced the incidence of complications related to diabetes mellitus, including the development of overt nephropathy. Moreover, in patients without a previous diagnosis of diabetes mellitus, ramipril, compared with placebo, significantly reduced the development of diabetes mellitus. Furthermore, compared with patients receiving placebo, patients receiving ramipril had a reduced rate of progression of carotid artery wall thickness. CONCLUSION Ramipril 10 mg/day can significantly reduce the incidence of MI, stroke or death from cardiovascular causes in patients aged > or =55 years who are at increased risk for the development of ischaemic cardiovascular events due to a history of stroke, coronary artery disease (with controlled blood pressure), diabetes mellitus plus at least one other risk factor or peripheral vascular disease but no heart failure or low ejection fraction. Therefore, in addition to dietary and lifestyle modifications, ramipril should be an integral part of secondary prevention therapy in patients at increased risk for the development of cardiovascular events.

Abstract
AIMS To estimate the cost-effectiveness of adding ramipril to conventional treatment in patients with heart failure after myocardial infarction from the perspective of the Spanish National Health System. METHODS AND RESULTS A retrospective analysis of the AIRE study was made, using previously published data from the clinical trial combined with local Spanish resource and cost data. A typical rehospitalisation for a heart failure episode would last an average of 11.6 days with an average cost of 350.80 per day. The incremental cost of ramipril per life-year gained in the baseline case was 1550.10 after 3.8 years of follow-up. Sensitivity analysis showed that the basic conclusions were robust in spite of extreme variations in the values of the key parameters of the model. CONCLUSION The use of ramipril in addition to conventional treatment in heart failure patients after myocardial infarction is cost-effective both according to currently accepted international standards of what constitutes a cost-effective intervention and also indirectly by comparing the results with similar pharmaceutical products financed under the Spanish National Health System.

Abstract
Angiotensin converting enzyme inhibitors like captopril, enalapril, lisinopril, trandopril and ramipril may rarely induce a life threatening angioedema. We present two cases of severe angioedema induced by enalapril and ramipril along with possible precipitating factors observed in these patients. The importance of prompt recognition and early management of such cases is emphasized.
