Valsartan is a highly selective angiotensin II AT1-receptor antagonist for the treatment of hypertension. Valsartan is mainly excreted into the bile in unchanged form. Because valsartan has an anionic carboxyl group, we hypothesized that a series of organic anion transporters could be involved in its hepatic clearance. In this study, to identify transporters that mediate the hepatic uptake and ...

OBJECTIVES The overall objective of this study was to estimate the costs and outcomes associated with treatment with valsartan for post-myocardial infarction (post-MI) patients with left ventricular systolic dysfunction, heart failure, or both, who are not suitable for treatment with angiotensin-converting enzyme (ACE) inhibitors, compared to placebo. METHODS A Markov model, using data drawn ...

Angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and diuretics may exert synergistic antiproteinuric effects. Eighteen patients with a proteinuria >1 g/24 h after 6 mo of treatment with ramipril at 5 mg/d were assigned to receive in random order ramipril at 10 mg/d, valsartan at 160 mg/d, or combined ramipril at 5 mg/d and valsartan at 80 mg/d in addition to their antihy...

The protective effect of aliskiren, a direct renin inhibitor, against hypertensive cardiovascular and renal injury remains to be defined. This study was undertaken to examine the protective effects of the combination of aliskiren and valsartan, an angiotensin receptor blocker, against cardiovascular and renal injury. Endothelial NO synthase-deficient mice, subjected to cuff injury of femoral ar...

BACKGROUND Low systolic blood pressure (SBP) is a risk factor for adverse outcomes in patients with heart failure (HF). Valsartan improved morbidity rates in the Valsartan Heart Failure Trial (Val-HeFT) despite a reduction in SBP. The aim of the present study was to investigate the relationship between the SBP-lowering effects of valsartan and its cardiovascular protective effects in this popul...

: To treat hypertension, combining two or more antihypertensive drugs from different classes is often necessary. β-Blockers and renin-angiotensin-aldosterone system inhibitors, when combined, have been deemed 'less effective' based on partially overlapping mechanisms of action and limited evidence. Recently, the single-pill combination (SPC) of nebivolol (Neb) 5 mg - a vasodilatory β1-selective...

We hypothesized that aliskiren provides renoprotection in diabetic animals that did not receive sufficient renoprotection by AT1-receptor antagonist treatment. Type 2 diabetic KKAy mice were treated with group 1: vehicle or group 2: valsartan (15 mg/kg per day) from 12 to 16 weeks of age. The mice were subsequently divided into 4 groups and treated with the following combinations of drugs for a...

BACKGROUND Angiotensin II is elevated in malignant hypertension. We tested the hypothesis that angiotensin II type 1 receptor blockade can prevent the development of malignant hypertension even in the absence of a blood pressure-lowering effect. METHODS AND RESULTS Two-kidney, 1-clip rats were followed up for 28 days; blood pressure was measured by tail-cuff plethysmography and intra-arterial...

INTRODUCTION Blockade of the renin-angiotensin system (RAS) is a critical approach to the management of hypertension, especially in proteinuric patients. It is well proven that the direct renin inhibitor aliskiren shows comparable clinical efficacy to the angiotensin II receptor blocker valsartan on blood pressure control and albuminuria. However, there is only limited data on the hand-to-hand ...

We reviewed the Chinese and English literature for the efficacy and safety data of valsartan monotherapy or combination therapy in Chinese hypertensive patients. According to the data of ten randomized controlled trials, valsartan monotherapy was as efficacious as another angiotensin receptor blocker or other classes of antihypertensive drugs, excepting the slightly inferior diastolic blood pre...
