Achieving blood pressure (BP) targets in stage 2 hypertension usually requires two or more drugs, which should be selected from different classes. This study compared the efficacy and tolerability of amlodipine/valsartan with amlodipine in patients with stage 2 hypertension. In this multicenter, randomized, double-blind, 8-week study, 646 patients with stage ...

Renin-angiotensin system blockade reduces proteinuria and prevents nephropathy progression in patients with type 2 diabetes mellitus (T2D). Experimental evidence demonstrates that angiotensin receptor blockers (ARBs) possess anti-inflammatory potential, which might contribute to reducing proteinuria and providing renoprotection. We conducted a multicentre, double-blind, prospective, parallel-group non-inferiority study of 885 hypertensive [systolic ...
Karalliedde Janaka - - 2008
Increased arterial stiffness, as estimated from aortic pulse wave velocity (Ao-PWV), and albuminuria are independent predictors for cardiovascular disease in type 2 diabetes mellitus (T2DM). Whether angiotensin receptor blockers (ARBs), drugs with cardio-renal protective effects, improve Ao-PWV to a greater extent than other equipotent antihypertensive medications remains unclear. After a ...

BACKGROUND: Hypertension markedly increases the already high risk for cardiovascular complications in patients with diabetes mellitus. Less than one in eight patients with hypertension and type 2 diabetes have adequately controlled blood pressure. As a result, antihypertensive combinations are now widely used in management of hypertension associated with diabetes. METHODS: ...
Tissot Alain C - - 2008
BACKGROUND: Hypertension can be controlled adequately with existing drugs such as angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers. Nevertheless, treatment success is often restricted by patients not adhering to treatment. Immunisation against angiotensin II could solve this problem. We investigated the safety and efficacy of CYT006-AngQb-a vaccine based on ...

OBJECTIVES: This double-blind study compared long-term efficacy, safety and tolerability of the oral direct renin inhibitor aliskiren and the angiotensin-converting enzyme inhibitor ramipril alone and combined with hydrochlorothiazide in patients with hypertension. METHODS: After a 2-4-week placebo run-in, 842 patients [mean sitting diastolic blood pressure (msDBP) 95-109 mmHg] were randomized ...
Conen D - - 2008
BACKGROUND: The Val-MARC trial showed that the angiotensin receptor blocker valsartan reduces high-sensitivity C reactive protein (hsCRP) levels, an effect that is independent of blood pressure, and seems to be neutralised by the addition of hydrochlorothiazide. OBJECTIVE: To evaluate whether valsartan influences soluble intercellular adhesion molecule 1 (sICAM-1) or vascular ...

Some beta-blockers are less effective in reducing central blood pressure than other antihypertensive drugs, which may explain the higher rate of events in subjects randomized to atenolol in recent trials. We hypothesized that nebivolol, a mixed beta-blocker/nitro-vasodilator, would be more effective than atenolol in reducing central blood pressure and augmentation ...

Angiotensin II type-1 receptor blockers (ARBs) are regarded as first-line treatments for type-2 diabetes with hypertension. Despite the availability of various types of ARBs, there are no comparative studies of their effects on patients with diabetes. In this open-label prospective crossover study, we compared the effects of olmesartan (20 mg/day) ...

By pre-synaptic stimulation of DA(2)-dopaminergic and alpha(2)-adrenergic receptors, nolomirole inhibits norepinephrine secretion from sympathetic nerve endings. We performed a clinical study with nolomirole in patients with heart failure (HF). The study was designed as a multicentre, double blind, parallel group trial of 5 mg b.i.d. of nolomirole (n=501) versus placebo ...

Guidelines stress the importance of the simultaneous management of multiple cardiovascular risk factors. This can in part be achieved by coadministration of lipid-lowering and antihypertensive treatments. Potential pharmacodynamic interaction between drugs should be investigated as part of developing single-pill combinations. The Respond trial assessed whether combining amlodipine to treat hypertension ...

BACKGROUND: Angiotensin II-mediated increases in sympathetic activity may contribute to smaller blood-pressure decreases in response to dihydropyridines in young versus older hypertensive patients. We evaluated whether quinapril unmasks angiotensin II-dependent sympathetic activity on amlodipine. METHODS: In this double-blind, randomized, clinical trial, young mild hypertensives were randomized to quinapril for 1 ...

Both strict blood pressure control and efferent artery dilatation are critical in reducing proteinuria, which in turn helps to regulate blood pressure. Benidipine, an L- and T-type calcium channel blocker, has the potential for increased effectiveness compared with L-type-dominant calcium channel blockers such as amlodipine. Therefore, we evaluated blood pressure ...

Valsartan administration at bedtime as opposed to on wakening improves the sleep time-relative blood pressure decline toward a more dipper pattern without loss in 24-hour efficacy. Yet to be determined is whether this administration time-dependent efficacy is a class-related feature, characteristic of all angiotensin receptor blockers or specific only to ...

The antihypertensive efficacy and safety of the direct renin inhibitor aliskiren were assessed in a pooled analysis of data from seven randomized, multicenter studies. Data were available for 7,045 patients (mean age 52.5 to 59.8 years, 50.2 to 72.5% men) with mild-to-moderate hypertension (mean sitting diastolic blood pressure [msDBP] 95 ...

The period of early morning blood pressure surge is associated with a higher incidence of cardiovascular events than at other times of the day. Antihypertensive medication given once daily in the morning may not protect against this surge if its duration of action is too short. We compared telmisartan, an ...
