Rationale for and design of the CREATIVE-AF trial: randomized, double-blind, placebo-controlled, crossover study of the effect of irbesartan on oxida…

2008

Background and objective: Atrial fibrillation (AF) is the most common cardiac arrhythmia. Recent studies suggest there is an angiotensin II-dependent increase in adhesion molecules and oxidative stress parameters during AF. These alterations appear to contribute to inflammatory and prothrombotic changes in the atrial endocardium (‘endocardial remodelling’), suggesting that patients with increased levels of these factors might be at risk of thromboembolic events. The purpose of the CREATIVE-AF (Impact of Irbesartan on Oxidative Stress and C-Reactive Protein Levels in Patients with Persistent Atrial Fibrillation) trial is to prove the principle concept that blockade of angiotensin II type 1 r…

Angiotensin II antagonists - an assessment of their acute toxicity.

2013

In Germany, increasing prescription rates of angiotensin II antagonists resulted in rising enquiries to Poisons Information Centres (PICs) during the last decade. Therefore, we aimed to assess their acute toxicity for deriving triage recommendations.An observational case series with data collected retrospectively from eight PICs in Austria, Germany and Switzerland. Inclusion criteria were monoexposure, defined dose, and documented follow-up.In total, 206 cases of exposures to angiotensin II antagonists were included (candesartan, 94; eprosartan, 3; irbesartan, 20; losartan, 26; olmesartan, 16; telmisartan, 18; and valsartan, 29). The median dose expressed as a multiple of their maximum dail…

The KARTAN study: a postmarketing assessment of Irbesartan in patients with hypertension.

2004

An important purpose of postmarketing surveillance of drugs is to better characterize the safety profile of drug therapy in the clinical setting. Another goal is to confirm the effectiveness of these drugs in patients who are candidates for antihypertensive therapy and who may have been excluded from Phase III studies. Irbesartan is a long-acting angiotensin II-receptor blocker specific for the angiotensin 1-receptor subtype that, in clinical trials in patients with hypertension, reduces blood pressure.The KARTAN (this word was derived from the first and last syllables of Karvea [trademark of Bristol-Myers Squibb Group, Madrid, Spain] and irbesartan) study was designed to confirm and extend…

Novo, S. et al. Aliskiren: Just a New Drug for Few Selected Patients or an Innovative Molecule Predestinated to Replace Arbs and Ace-Inhibitors? Phar…

2011

The renin-angiotensin-aldosterone system (RAAS) plays a dominant role in the pathophysiology of hypertension, diabetes mellitus, chronic kidney disease and chronic heart failure. Therefore, drugs that block key components of the RAAS such as ACE inhibitors (ACEI) and angiotensin receptor blockers (ARBs) have gained wide clinical use for these indications. Despite progress, the morbidity and mortality of patients treated with ACEI or ARBs remain high. Aliskiren (Tekturna, Rasilez) is the first orally active inhibitor of renin approved for clinical use as an antihypertensive agent. The development program has established that at the licensed doses of 150 mg and 300 mg. Aliskiren is effective …

AT1-receptor blockade with irbesartan improves peripheral but not coronary endothelial dysfunction in patients with stable coronary artery disease

2007

Activation of the renin-angiotensin-aldosterone system plays an important role in the pathogenesis of endothelial dysfunction and atherosclerosis. Studies evaluating the effect of AT1-receptor blockers on endothelial dysfunction in patients with coronary artery disease (CAD) revealed mixed results. Studies addressing the effects of AT1-receptor blockers on the coronary and peripheral function in the same study population, are still lacking. We therefore aimed to test the effects of long-term therapy with the AT1-receptor blocker irbesartan (IRB) on both, the coronary and peripheral endothelial function in patients with CAD. Seventy-two patients with CAD were randomly assigned to double-blin…

The effect of RAAS blockade on markers of renal tubular damage in diabetic nephropathy: u-NGAL, u-KIM1 and u-LFABP.

2012

Blockade of the renin-angiotensin-aldosterone system (RAAS) affects both the glomerulus and tubules. We aimed to investigate the effect of irbesartan on the tubular markers: urinary (u) neutrophil gelatinase associated protein (NGAL), Kidney injury molecule 1 (KIM1) and liver-fatty acid-binding protein (LFABP).A substudy of a double-masked, randomized, cross-over study including 52 patients with type 2 diabetes, hypertension and microalbuminuria. After 2 months washout of all antihypertensive medication except bendroflumethiazid, patients were treated in random order with irbesartan 300, 600 and 900 mg for 2 months.Urinary tubular markers at baseline and after each treatment period (ELISA),…
