Two possible sites of renal metabolism exist: intracellular, by enzymes within the peritubular cells, and intraluminal, by ecto-enzymes embedded on the brush border membrane. The esterolysis of enalapril to its dicarboxylate metabolite, enalaprilat, was studied in the isolated perfused, nonfiltering rat kidney preparation (NFK) and compared with that observed for the isolated perfused rat kidne...

BACKGROUND The aim of the present study was to analyze the changes in left ventricular diastolic function that occur in patients with chronic severe left ventricular systolic dysfunction in the absence or presence of prolonged therapy with an angiotensin converting enzyme inhibitor. METHODS AND RESULTS Left ventricular function data (cineangiography plus Millar, frame-by-frame analysis) and r...

Background. The aim of the present study was to analyze the changes in left ventricular diastolic function that occur in patients with chronic severe left ventricular systolic dysfunction in the absence or presence of prolonged therapy with an angiotensin converting enzyme inhibitor. Methods and Results. Left ventricular function data (cineangiography plus Millar, frame-by-frame analysis) and r...

Pullulan, a water soluble, bioadhesive and biocompatible biopolymer is used as an efficient matrix for enalapril maleate film preparation. The obtained film contains as much as 67% of enalapril maleate, relative to the initial amount used for experiments. The drug content was evaluated by using 1 H-NMR and UV-vis spectroscopy. The pullulanenalaprilmaleate blends exhibit good physicochemical pro...

CONTEXT The effect of antihypertensive drugs on cardiovascular events in patients with coronary artery disease (CAD) and normal blood pressure remains uncertain. OBJECTIVE To compare the effects of amlodipine or enalapril vs placebo on cardiovascular events in patients with CAD. DESIGN, SETTING, AND PARTICIPANTS Double-blind, randomized, multicenter, 24-month trial (enrollment April 1999-Ap...

Oxidative stress is involved in both the pathogenesis and complications of diabetes. ACE inhibitors can slow the progression of cardiac and renal impairments related to diabetes. The effect of enalapril treatment on oxidative stress and tissue injury was studied in hearts, kidneys, and livers from streptozotocin-induced diabetic rats. Twenty-four rats were divided into the following groups: str...

Background: Central renin angiotensin system has an important role on the cerebral microcirculation and metabolism. Our previous work showed that inhibition of angiotensin converting enzyme (ACE) activity prior to induction of ischemia protected the brain from severe ischemia/reperfusion (I/R) injuries. This study evaluated the impacts of post-ischemic inhibition of ACE, enalapril, on brain inf...

Previous studies have shown that angiotensin II (Ang II), by mediating rapid recruitment of collateral circulation, has a protective effect in the setting of acute ischaemia. In an experimental model of acute cerebral ischaemia in the gerbil, Fernandez et al. have reported that the mechanism of the protective effect of Ang 11 is blood pressure (BP)-independent, and that the AT1-receptor antagon...

OBJECTIVES We investigated the effects of enalapril therapy on plasma tissue factor (TF), tissue factor pathway inhibitor (TFPI) and monocyte chemoattractant protein-1 (MCP-1) levels in patients with acute myocardial infarction. BACKGROUND Macrophages express TF in human coronary atherosclerotic plaques. Both TF and TFPI are major regulators of coagulation and thrombosis. Monocyte chemoattrac...

Maternal low protein diet programs offspring to develop hypertension as adults. Transient exposure to angiotensin converting enzyme inhibitors or angiotensin II receptor blockers can result in improvement in hypertension. Male rats whose mothers received a low protein diet during the last half of pregnancy were given either vehicle, continuous enalapril (CE) in their drinking water or were give...
