BACKGROUND Angiotensin II subtype-1 receptor antagonists represent a valuable new class of drugs in the treatment of diabetic nephropathy. The aim of our study was to evaluate the optimal dose of losartan for renoprotection and blood pressure reduction in diabetic nephropathy. METHODS Fifty consecutive hypertensive type 1 diabetic patients with diabetic nephropathy received increasing doses o...

The losartan metabolite EXP3174 exhibits angiotensin II receptor 1 (AT1R)-blocking properties, whereas the metabolite EXP3179 potently induces the activity of the insulin-sensitizing peroxisome proliferator-activated receptor gamma (PPARgamma) as a partial agonist in vitro. We investigated whether chronic treatment with losartan leads to sufficient serum levels of EXP3179 to activate PPARgamma ...

OBJECTIVE To compare the regression of left ventricular hypertrophy in patients with moderate hypertension treated with enalapril, losartan or a combination of the two drugs at lower doses. METHODS Patients of both sexes with moderate hypertension confirmed by ambulatory monitoring of arterial blood pressure and with left ventricular hypertrophy on echocardiogram were assigned to three groups...

Inhibition of angiotensin II type 1 receptor (AT1R) is an important therapy in the management of hypertension, particularly in the immediate post-myocardial infarction period. Yet, the role of AT1R in the acute onset of myocardial ischemia and reperfusion injury still remains controversial. Thus, the present study determined the effects of chronic losartan treatment on heart ischemia and reperf...

PURPOSE OF STUDY To evaluate the effect of the angiotensin II type 1 receptor antagonist, losartan, on post-transplant erythrocytosis. METHODS We retrospectively analyzed the influence of losartan therapy on haemoglobin levels of renal transplant recipients. Twenty-eight patients who received losartan therapy to control hypertension were divided into two groups. In 10 patients, losartan thera...

We investigate whether combined treatment with losartan, an angiotensin II receptor blocker, and exercise training (ET) in spontaneously hypertensive rats (SHR) would have an additive effect in reducing hypertension and improving baroreflex sensitivity when compared with losartan alone. Male SHR (8 weeks old) were assigned to 3 groups: sedentary placebo (SP, N = 16), sedentary under losartan tr...

Elevated aldosterone levels induce a spironolactone-inhibitable decrease in cardiac sarcolemmal Na+-K+ pump function. Because pump inhibition has been shown to contribute to myocyte hypertrophy, restoration of Na+-K+ pump function may represent a possible mechanism for the cardioprotective action of mineralocorticoid receptor (MR) blockade. The present study examines whether treatment with the ...

Losartan, an AT1 angiotensin II (ANG II) receptor non-peptide antagonist, induces an increase in mean arterial pressure (MAP) when injected intracerebroventricularly (icv) into rats. The present study investigated possible effector mechanisms of the increase in MAP induced by icv losartan in unanesthetized rats. Male Holtzman rats (280-300 g, N = 6/group) with a cannula implanted into the anter...

BACKGROUND There are on-going initiatives in Scotland to improve the quality and efficiency of prescribing in primary care. Activities to enhance prescribing of angiotensin-converting enzyme inhibitors (ACEIs) versus angiotensin receptor blockers (ARBs) include prescribing guidance, guidelines, benchmarking, prescribing targets and financial incentives. These measures stabilised reimbursed expe...

objective(s) four novel losartan analogues 5a-d were synthesized by connecting a dihydropyridine nucleus to imidazole ring. the effects of 5a and 5b on angiotensin receptors (at') and l-type calcium channels were investigated on isolated rat aorta. materials and methods aortic rings were pre-contracted with 1 pm angiotensin ii or 80 mm kcl and relaxant effects of losartan, nifedipine, 5a a...
