The aim of the present study was to evaluate the effect of low-dose spironolactone initiated during the early stages of hypertension development and to assess the effects of chronic pressure overload on ventricular remodeling in rats. Male spontaneously hypertensive rats (SHRs) (4 weeks) were randomized to receive daily spironolactone (20 mg/kg) or vehicle (mineral oil) from 4 weeks to 8 months...
Reduced coronary flow reserve (CFR), an indicator of coronary microvascular dysfunction, is seen in type 2 diabetes mellitus (T2DM) and predicts cardiac mortality. Since aldosterone plays a key role in vascular injury, the aim of this study was to determine whether mineralocorticoid receptor (MR) blockade improves CFR in individuals with T2DM. Sixty-four men and women with well-controlled diabe...
In the spontaneous hypertensive rat, overexpression of the renal Na-independent L-amino acid transporter LAT2 is organ specific, precedes the onset of hypertension, correlates negatively with plasma aldosterone, and parallels the enhanced ability to take up L-DOPA and form renal dopamine. The present study evaluated the role of aldosterone on transcript and protein abundance of Na-independent a...
Administration of the mineralocorticoid receptor antagonist spironolactone prevents the development of chronic kidney disease (CKD) after a severe ischemic injury. However, whether brief periods of ischemia lead to CKD and whether spironolactone administration after ischemia may be a useful therapeutic strategy to prevent the gradual deterioration of structure and function remains unexplored. N...
The role of spironolactone in resistant hypertension management is unclear. The aim of this prospective trial was to evaluate the antihypertensive effect of spironolactone in patients with true resistant hypertension diagnosed by ambulatory blood pressure monitoring. A total of 175 patients had clinical and complementary exams obtained at baseline and received spironolactone in doses of 25 to 1...
AIMS Renal failure is a major challenge in treating heart failure (HF) patients. HF medication may deteriorate renal function, but the impact thereof on outcome is unknown. We investigated the effects of HF medication on worsening renal function (WRF) and the relationship to outcome. METHODS AND RESULTS This post-hoc analysis of TIME-CHF (NT-proBNP-guided vs. symptom-guided management in chro...
The renin-angiotensin-aldosterone system and electrolyte levels in 11 patients with heart failure controlled on digoxin and frusemide were investigated after separate periods of Slow K, spironolactone, and amiloride therapy. When spironolactone or amiloride replaced Slow K, distinct parallel increments in the levels of renin, angiotensin II, and aldosterone resulted. Though plasma potassium was...
We measured the cross reactivity of two medications--digitoxin and spironolactone--in two digoxin radioimmunoassay (liquid and solid-phase) kit procedures. Both tests showed similar average percentages of cross reactivity with digitoxin (7.2 and 8.9% for intravenous, and 11.9 and 10.9% for oral administration), but no cross reactivity with spironolactone or its metabolites after equal intraveno...
Background: Spironolactone is a conventional drug widely in use for the treatment of heart failure and hypertension patients. On other side recent studies have reported spironolactone can prevent growth resistance cancer stem cells (CSCs), by inhibiting DNA double-strand break (DSB) repair; suggesting its potential application therapy. Objectives: Our study aimed at assessing cytotoxicity human...
Hypertensive patients are said to be resistant to therapy when their pressures exceed goal despite treatment with 3 antihypertensive drugs. The tendency of most clinicians is to treat resistant patients with stronger and stronger agents in higher and higher doses. By contrast, a few reports in the literature suggest surprising usefulness of spironolactone, a relatively weak diuretic, in resista...
