Carvedilol is a beta1-, beta2-, and alpha1-adrenergic blocker that is approved for the treatment of hypertension. A new once-daily, controlled-release (CR) formulation of carvedilol has been shown to be effective in a double-blind, randomized, multicenter, placebo-controlled, parallel-group study. In this article, we summarize the primary results of, and present additional ...

Many patients with hypertension, especially those at increased risk because of additional cardiovascular risk factors, require treatment with more than one antihypertensive agent to achieve target blood pressure (BP) goals. Many different classes of antihypertensive agents are available: a renin-angiotensin-aldosterone system (RAAS) blocker and a diuretic are widely used in ...

Olmesartan medoxomil is an angiotensin II receptor blocker with similar antihypertensive efficacy as the calcium channel blocker amlodipine besylate in patients with mild-to-moderate hypertension. In addition to a drug's ability to lower blood pressure, the effectiveness of the agent in enabling patients to achieve specific blood pressure targets is an ...

Increased levels of high-sensitivity C-reactive protein (hsCRP) are associated with incident hypertension as well as cardiovascular events, and angiotensin II is a potent proinflammatory mediator. However, whether angiotensin receptor blockade lowers hsCRP is uncertain. We performed a randomized trial in which 1668 patients with stage 2 hypertension were treated with ...

Combining an NSAID and paracetamol (acetaminophen) has in some studies given superior analgesia compared with the single drugs. In other trials no additive effect has been found. We have investigated the effect of this drug combination on the pressure pain tolerance threshold (PPTT), a reproducible correlate to clinical pain. The ...

Although magnesium provides cerebral protection in animal stroke models, magnesium therapy has significant side effects in humans. Therefore, we sought to examine the incidence of alpha-agonist treated hypotension in our ongoing, prospective, randomized, double-blind, placebo-controlled Phase I/IIa dose escalation study of magnesium therapy in patients undergoing carotid endarterectomy. Eighty patients ...

OBJECTIVE: Angiotensin-converting enzyme inhibitors plus dihydropyridine calcium channel blockers or low-dose thiazide diuretics are considered first-line therapies in hypertensive diabetic patients as glucose metabolism is not relevantly affected. Most diabetic patients require at least two different drug classes to achieve the recommended target blood pressure of 130/85 mmHg. This controlled ...

A low-dose sustained-release (SR) formulation of the thiazide-type diuretic indapamide, indapamide SR (Natrilix SR), retains the antihypertensive activity of the immediate-release (IR) formulation, with a smoother pharmacokinetic profile. In well controlled 12- to 52-week clinical trials, indapamide SR 1.5 mg/day was well tolerated and reduced blood pressure as effectively as ...

This 8-week, multicenter study evaluated the efficacy and safety of candesartan cilexetil (CC, 8-16 mg) in elderly (>65 years) hypertensive patients. Patients (n=3013) received CC 8 mg during 8 weeks which eventually doubled to CC 16 mg at week 4 if blood pressure remained uncontrolled (> or = 140/90 mmHg). ...

Measurement of blood pressure in the clinic may provide a false impression of blood pressure control. Ambulatory blood pressure monitoring (ABPM) allows the automatic recording of the circadian variation in blood pressure and evaluation of the efficacy of antihypertensive medication throughout the dosing interval. Ambulatory blood pressure provides more effective ...

BACKGROUND: The objective of this study was to evaluate the safety and efficacy of once-daily OROS methylphenidate (MPH) in the treatment of adults with DSM-IV attention-deficit/hyperactivity disorder (ADHD). METHODS: We conducted a randomized, 6-week, placebo-controlled, parallel-design study of OROS MPH in 141 adult subjects with DSM-IV ADHD, using standardized instruments ...
Davies Justine - - 2005
INTRODUCTION: It has been suggested that angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin II receptor blockers (ARBs) have a differential effect on brachial and aortic haemodynamics. This is why they seem to have beneficial effects that are beyond brachial blood pressure (BP) lowering. We aimed to investigate if this was the ...

OBJECTIVE: To test whether adding hydrochlorothiazide (HCTZ) (12.5 or 25 mg) to olmesartan 20 mg improves 24-h blood pressure in patients whose conventional diastolic blood pressure is inadequately controlled by olmesartan monotherapy. PATIENTS: Male and female patients > or = 18 years with mean sitting diastolic blood pressure (DBP) of ...
Neutel Joel M - - 2005
Systolic hypertension is predominant among patients over 50 years of age, is a more important cardiovascular risk factor than diastolic blood pressure, and is more difficult to control than diastolic blood pressure. Consequently, the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood ...

OBJECTIVE: Few data are available comparing the effects of monotherapy and combination therapy on target organ damage. The PICXEL study compared the efficacy of a strategy based on first-line combination with perindopril/indapamide versus monotherapy with enalapril in reducing left ventricular hypertrophy (LVH) in hypertensive patients. METHODS: In this 1-year multicentre ...

The objective of the study was to demonstrate that reduction in mean 24-hour diastolic blood pressure with 160 mg valsartan and 12.5 mg hydrochlorothiazide was not inferior to 10 mg amlodipine in hypertensive blacks. A total of 482 blacks with stage 1 and stage 2 hypertension (mean seated blood pressure ...

An early observational study suggested that ginseng could elevate blood pressure. This caused concern because 4.5% of American adults use ginseng, with a popular choice being North American ginseng. To date, North American ginseng lacks hemodynamic evaluation; therefore, we conducted a randomized, double-blinded, controlled trial to investigate its effect on ...
