Volume overload is an important clinical target in heart failure management, typically addressed using loop diuretics. An important and challenging subset of heart failure patients exhibit fluid overload despite significant doses of loop diuretics. One approach to overcome loop diuretic resistance is the addition of a thiazide-type diuretic to produce diuretic synergy via "sequential nephron bl...

BACKGROUND In chronic heart failure (CHF) patients there is a wide variability in the minimal effective diuretic dose. The aim of this study is to evaluate whether renal resistance index (RRI) is associated to baseline diuretic dose and the changes at one year. METHODS AND RESULTS 250 outpatients in a stable condition and in conventional therapy were enrolled. Baseline RRI was calculated by r...

Purpose: To evaluate the diuretic activity and acute toxicity profile of the crude aqueous extract of Achyranthes aspera using animal models. Methods: Albino rats of either sex were divided into five groups (six animals in each group). The control group received normal saline (10 ml/kg), the reference group received furosemide (10 mg/kg) and the test groups were administered different doses of ...

luid removal is an important component of heart failure treatment to relieve signs and symptoms of edema and to improve oxygenation. In this regard, diuretic therapy should be initiated without delay, and indeed early intervention has been associated with better outcomes for patients hospitalized with acute decompensated heart failure (ADHF).1,2 Loop diuretics have a high natriuretic potency by...

BACKGROUND Diuretic agents are widely used on the treatment of water retention related diseases, among which acetazolamide (AZA) acts originally as a carbonic anhydrase (CA) inhibitor. Aquaporin-1 (AQP1) being located in renal proximal tubules is required for urine concentration. Previously our lab has reported AZA putatively modulated AQP1. Aim of this study is to testify our hypothesis that r...

BACKGROUND The effectiveness of the clinical strategy of empiric potassium supplementation in reducing the frequency of adverse clinical outcomes in patients receiving loop diuretics is unknown. We sought to examine the association between empiric potassium supplementation and 1) all-cause death and 2) outpatient-originating sudden cardiac death (SD) and ventricular arrhythmia (VA) among new st...

The reaction indices of π-electronic structures of the diuretics, xanthine, thiazide and triazine derivatives were calculated. An attempt was made to explain the potency of the diuretic action in the light of quantum chemistry. The reaction indices of xanthine derivatives, the first frontier superdelocalizability at the substi tuent occupying the 7-position of the highest occupied orbital an...

Purpose: Trigonella foenum-Graceum Linn commonly known as fenugreek has a long history of traditional use in ayurveda and Chinese medicine and has been used for numerous indications, including labor induction, aiding digestion and to improve metabolism and diuresis. The present study was to evaluate the diuretic activity as traditionally claimed, from successive petroleum ether, benzene, ethano...

OBJECTIVES We sought to determine if ultrafiltration before intravenous (IV) diuretics in patients with decompensated heart failure and diuretic resistance results in euvolemia and early discharge without hypotension or worsening renal function. BACKGROUND Heart failure patients with renal insufficiency and diuretic resistance have increased hospital mortality and length of stay. Peripheral v...

1. Plasma renin activity, body weight and blood pressure were measured before and after 7 days' treatment with bendrofluazide in ten hypertensive subjects. They were then treated with bendrofluazide alone (5 mg daily) for a minimum of 3 years. The diuretic was then discontinued and the measurements were repeated before and again after 7 days with bendrofluazide. The results were compared with t...
