The renin-angiotensin-aldosterone system (RAAS) plays a pivotal role in the pathogenesis of hypertension (HTN). Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are first line anti-HTN drug classes that are potent, effective and largely safe. Direct renin inhibitors (DRIs) have shown similar blood pressure (BP) reduction but more side effects. The efficacy of ACEIs and ARBs (for cardiovascular, cerebrovascular and renal protection) has been promoted to extend beyond what could be explained by BP reduction alone...

OBJECTIVE: Left ventricular hypertrophy (LVH) is prevalent in chronic kidney disease (CKD) and a major cause of cardiovascular morbidity and mortality. Treatment of LVH in CKD is based on blood pressure control. The Kruppel like factor 15 (KLF15) is expressed in the heart and acts as a repressor of cardiac hypertrophy and fibrosis. The role of cardiac KLF15 in the development of LVH in rats with CKD secondary to subtotal nephrectomy (STNx) or the effects of ACE inhibition on KLF15 levels has not been addressed previously...

Rheumatoid arthritis (RA) is a chronic inflammatory disease with a potential cardiovascular (CV) risk. Flow-mediated vasodilation (FMD) is an ultrasonic method to evaluate endothelial function. RA is a contributor to endothelial dysfunction, a CV risk. Relevant insights on the improvement of the CV outcomes in RA patients may be obtained by a systematic review of trials that investigated the effects of RA treatment on FMD in RA patients. This review found that treatments with antirheumatic drugs and some non-antirheumatic drugs could improve the FMD in RA patients...

BACKGROUND: A multidrug treatment strategy that targets urinary proteins with an angiotensin-converting enzyme (ACE) inhibitor and angiotensin receptor blocker (ARB) up-titrated to the respective maximum tolerated dose combined with intensified blood pressure (BP) control has been found to prevent renal function loss in adults with proteinuric nephropathies. Herein, we investigated the effects of this treatment protocol in the pediatric patient population. METHODS: From May 2002 to September 2014 we included in this observational, longitudinal, cohort study 20 consecutive children with chronic nephropathies and 24-h proteinuria of >200 mg who had received ramipril and losartan up-titrated to the respective maximum approved and tolerated doses [mean (standard deviation) dose:2...

Acute kidney injury (AKI) and progressive chronic kidney disease (CKD) are intrinsically tied syndromes. In this regard, the acutely injured kidney often does not achieve its full regenerative capacity and AKI directly transitions into progressive CKD associated with tubulointerstitial fibrosis. Underlying mechanisms of such AKI-to-CKD progression are still incompletely understood and specific therapeutic interventions are still elusive. Because epigenetic modifications play a role in maintaining tissue fibrosis, we used a murine model of ischemia-reperfusion injury to determine whether aberrant promoter methylation of RASAL1 contributes causally to the switch between physiological regeneration and tubulointerstitial fibrogenesis, a hallmark of AKI-to-CKD progression...

The binding interaction between a typical angiotensin-converting enzyme inhibitor (ACEI), ramipril, and a transport protein, bovine serum albumin (BSA), was studied in vitro using UV-vis absorption spectroscopy, steady-state fluorescence spectroscopic titration, synchronous fluorescence spectroscopy, three dimensional fluorescence spectroscopy, circular dichroism and molecular docking under the imitated physiological conditions (pH=7.4). The experimental results suggested that the intrinsic fluorescence of BSA was quenched by ramipril thought a static quenching mechanism, indicating that the stable ramipril-BSA complex was formed by the intermolecular interaction...

Prior studies have shown that overexpression of ACT A can lead to ventricular remodeling in rat models of heart failure. Furthermore, recently work studying demonstrated that stimulation of activin An expression in rat aortic smooth muscle (RASM) cells by angiotensin II (Ang II). Ramipril is a recently developed angiotensin converting enzyme (ACE) inhibitor. To investigate the effects of Ramipril on expression of ACT A-FS, we established the rat model of heart failure after myocardial infarction (MI), and divided into either a sham operation (SO), MI, or MI-Ramipril group...

We present a dendrimer-based hybrid formulation strategy to explore the potential of poly (amidoamine) PAMAM dendrimers to be used as drug carriers for combination therapy of an anti-hypertensive drug ramipril (RAPL) and a diuretic hydrochlorothiazide (HCTZ). The drug-dendrimer complexes were prepared by phase-equilibration method. The results showed that the solubility of RAPL and HCTZ was dependent on dendrimer concentration and pH of dendrimer solution. The solubility profile of both RAPL and HCTZ dendrimer complexes illustrated a non-linear relationship with dendrimer concentration...

Recently, the Action to Control Cardiovascular Risk in Diabetes (ACCORD) blood pressure (BP) trial enrolled 4733 participants with type 2 diabetes and randomized them to a target systolic blood pressure (SBP) of less than 120 mm Hg or 140 mm Hg. Despite the significant difference in the achieved SBP, there was no significant difference in the incidence of primary outcomes. Based on this evidence, the target SBP for diabetics has been revised in the majority of major guidelines. However, there is a steeper association between SBP and stroke in Asians than other ethnicities, with stroke being the leading cause of cardiovascular mortality...

We hypothesized that peroxisome proliferator-activated receptors (PPARs) might be involved in a complex protective action of ACE inhibitors (ACEi) in anthracyclines-induced cardiomyopathy. For purpose of study, we compared effects of ramipril on cardiac dysfunction, cardiac failure markers and PPAR isoforms in moderate and severe chronic daunorubicin-induced cardiomyopathy. Male Wistar rats were administered with a single intravenous injection of daunorubicin: 5mg/kg (moderate cardiomyopathy), or 15mg/kg (severe cardiomyopathy) or co-administered with daunorubicin and ramipril (1mg/kg/d, orally) or vehicle for 8 weeks...

Statins, such as simvastatin, and ACE inhibitors (ACEis), such as ramipril, are standard therapies for the prevention and treatment of cardiovascular diseases. These types of drugs are commonly administered together. More recently, angiotensin II type 1 receptor (AT1R) antagonists, such as candesartan cilexetil (candesartan), have been used in the place of, or in combination with, ACEis. Here, we investigated the effects of simvastatin and ramipril single and combination therapy, and candesartan treatment on the lifespan of isocalorically fed, long-lived, B6C3F1 mice...

BACKGROUND: The DENERHTN trial (Renal Denervation for Hypertension) confirmed the blood pressure-lowering efficacy of renal denervation added to a standardized stepped-care antihypertensive treatment for resistant hypertension at 6 months. We report the influence of adherence to antihypertensive treatment on blood pressure control. METHODS: One hundred six patients with hypertension resistant to 4 weeks of treatment with indapamide 1.5 mg/d, ramipril 10 mg/d (or irbesartan 300 mg/d), and amlodipine 10 mg/d were randomly assigned to renal denervation plus standardized stepped-care antihypertensive treatment, or the same antihypertensive treatment alone...
