INTRODUCTION: Previous studies of antihypertensive treatment of older patients have focused on blood pressure control, cardiovascular risk or adherence, whereas data on inappropriate antihypertensive prescriptions to older patients are scarce. OBJECTIVES: The aim of the study was to assess inappropriate antihypertensive prescriptions to older patients. METHODS: An observational, prospective multicentric study was conducted to assess potentially inappropriate prescription of antihypertensive drugs, in patients aged 75 years and older with arterial hypertension (HTN), in the month prior to hospital admission, using four instruments: Beers, Screening Tool of Older Person's Prescriptions (STOPP), Screening Tool to Alert Doctors to the Right Treatment (START) and Assessing Care of Vulnerable Elders 3 (ACOVE-3)...

Olmesartan is an angiotensin receptor blockers with actions similar to those of losartan; it is used for the treatment of high blood pressure by relaxing blood vessels for this reason blood can flow more easily. It could be used alone or in combination with other antihypertensive drugs. This chapter gives a comprehensive profile of olmesartan, containing detailed nomenclature, formulae, elemental analysis, and appearance of the drug. In addition this chapter also describes several methods of synthesis and usage of the olmesartan...

Hypertension is considered as the most common risk factor for cardiovascular diseases, also is regarded as a leading cause of the mortality and morbidity worldwide. The mechanisms underlying the pathological process of hypertension are not completely explained. However, there is growing evidence that increased oxidative stress plays an important role in the pathophysiology of hypertension. Several preclinical studies and clinical trials have indicated that antioxidant therapy is important for management of hypertension, using antioxidants compounds such as alpha tocopherol (Vit E) and ascorbic acid (Vit C), polyphenols with others and some antihypertensive drugs that are now in clinical use (e...

Fixed-dose triple drug combinations represent one of the latest innovations of pharmacotherapy for hypertension (HT). They combine a traditional renin-angiotensin system blocker, a diuretic and a calcium channel blocker. The main benefit is the simplification of treatment regimen because 3 different agents are combined at different doses in a single pill. Improving adherence to treatment partly explains why this kind of combination may effectively reduce blood pressure (BP). BP lowering by a single-pill triple-drug combination can be approximately predicted, by using appropriate formulas described in previous meta-analysis of randomized trials...

Heart failure (HF) with preserved ejection fraction (EF) (HFpEF) accounts for approximately 50% of HF cases and its prevalence relative to HF with reduced EF is rising. Hypertension (HT) is the most common co-morbidity in HFpEF patients and it is implicated in both the pathogenesis and the prognosis of the disease. Therefore, HT is a modifiable risk factor of high yield in HFpEF. We reviewed the literature for epidemiologic data supporting the co-aggregation of the two entities as well as patho-physiologic mechanisms linking HT to HFpEF...

Angiogenesis is fundamental for tumour development and progression. Thus, anti-angiogenic agents have been developed and are mainly vascular endothelial growth factor (VEGF) pathway inhibitors. However, these agents commonly exhibit cardiac and renal toxicity, proteinuria and hypertension (HT). In fact, with the use of anti-angiogenic agents a rapiddose-dependent increaseof blood pressure (BP) is observed. Thepossible mechanisms of VEGF inhibitors-induced HTinclude systemic endothelial dysfunction, renal impairment as well as vascular micro- and macroangiopathy...

Hypertension (HT) is present in >80% of patients undergoing haemodialysis (HD). Elevated blood pressure (BP) in hemodialysis patients is associated with cardiovascular events and mortality only when BP is recorded with home or ambulatory monitoring, since pre- and post-dialysis measurements are not valid estimates of BP levels during the inter-interval. Sodium and water overload is the most important of several mechanisms involved in HT development in HD. In this context, non-pharmacologic measures to ensure water and sodium balance by achieving patient dry weight and decreasing daily sodium intake, through modification of sodium level in the diet or in dialysis dialysate, are fundamental for HT control...

BACKGROUND: The effects of antihypertensive drug combination therapy on central blood pressure (BP) and augmentation index (AI) have not been fully elucidated. We investigated the effects of the direct renin inhibitor, aliskiren, or a diuretic added to an angiotensin II receptor blocker on AI in patients with essential hypertension. METHODS: A 24-week, prospective, multicentre, randomised, open-label study enrolled 103 patients already treated with valsartan. Participants were randomly allocated to receive either valsartan with aliskiren (V+A), or valsartan with trichlormethiazide (V+T)...

Dihydropyridine calcium-channel blockers are a known substrate for the cytochrome P450 isoform 3A4. Rifampicin, an antitubercular agent, is one of the most potent inducers of hepatic and intestinal CYP3A4 thus increasing dihydropyridine metabolism. We report a case of a 67-year-old hypertensive female treated with a 4-drug antihypertensive regimen including a dihydropyridine (nicardipine 50mg bid), who was admitted for septic arthritis of the knee requiring antibiotic treatment with teicoplanin 400mg od and rifampicin 600mg bid...

While the exploitation of the Sharpless asymmetric dihydroxylation as the source of chirality in the synthesis of acyclic molecules and saturated heterocycles has been tremendous, its synthetic utility toward chiral benzo-annulated heterocycles is relatively limited. Thus, in the search for wider applications of Sharpless asymmetric dihydroxylation-derived diols for the synthesis of benzo-annulated heterocycles, we report herein our studies in the asymmetric synthesis of (R)-1-((R)-6-fluorochroman-2-yl)ethane-1,2-diol, (R)-1-((S)-6-fluorochroman-2-yl)ethane-1,2-diol and (S)-6-fluoro-2-((R)-oxiran-2-yl)chroman, which have been used as late-stage intermediates for the asymmetric synthesis of the antihypertensive drug (S,R,R,R)-nebivolol...

PURPOSE OF REVIEW: Intradialytic hypertension occurs regularly in 10--15% of hemodialysis patients. A large observational study recently showed that intradialytic hypertension of any magnitude increased mortality risk comparable to the most severe degrees of intradialytic hypotension. The present review review discusses the most recent evidence underlying the pathophysiology of intradialytic hypertension and implications for its management. RECENT FINDINGS: Patients with intradialytic hypertension typically have small interdialytic weight gains, but bioimpedance spectroscopy shows these patients have significant chronic extracellular volume excess...
