AT1 antagonists is the most recent drug class of molecules against hypertension and they mediate their actions through blocking detrimental effects of angiotensin II (A-II) when acts on type I (AT1) A-II receptor. The effects of AT1 antagonists are not limited to cardiovascular diseases. AT1 receptor blockers may be used as potential anti-cancer agents - due to the inhibition of cell proliferation stimulated by A-II. Therefore, AT1 receptors and the A-II biosynthesis mechanisms are targets for the development of new synthetic drugs and therapeutic treatment of various cardiovascular and other diseases...

OBJECTIVES: To assess the incremental effects of adding extra antihypertensive drugs from a new class to a patient's regimen. DESIGN: Instrumental variable analysis of data from SPRINT (Systolic Blood Pressure Intervention Trial). To account for confounding by indication-when treatments seem less effective if they are administered to sicker patients-randomization status was used as the instrumental variable. Patients' randomization status was either intensive (systolic blood pressure target <120 mm Hg) or standard (systolic blood pressure target <140 mm Hg) treatment...

Jamshed Haneef, Renu Chadha
The present research work highlights the development of multicomponent solid form of the antihypertensive drug irbesartan (IRB) to improve its biopharmaceutical attributes. Mechanochemical synthesis of a new solid form of IRB with coformers having antioxidant properties (syringic acid, nicotinic acid, and ascorbic acid) resulted into three eutectic mixtures (EMs). Formation of eutectic was ascertained by differential scanning calorimetry whereas exact stoichiometry (50/50% w/w) was established by phase diagram and Tamman's triangle...

Catheter-based renal denervation is a new approach to treat hypertension via modulation of the renal sympathetic nerves. Although nonrandomized and small, open-label randomized studies resulted in significant reductions in office blood pressure 6months after renal denervation with monopolar radiofrequency catheters, the first prospective, randomized, sham-controlled study (Symplicity HTN-3) failed to meet its blood pressure efficacy end point. New clinical trials with new catheters have since been designed to address the limitations of earlier studies...

Hypertension is a major risk factor for ischemic cardiovascular disease and cerebrovascular disease, which are respectively the primary and secondary most common causes of morbidity and mortality across the globe. To alleviate the risks of hypertension, there are a number of effective antihypertensive drugs available. However, the optimal treatment blood pressure goal for antihypertensive therapy remains an area of controversy. The results of the recent Systolic Blood Pressure Intervention Trial (SPRINT) trial, which found benefits for intensive lowering of systolic blood pressure, have been debated for several reasons...

BACKGROUND: Erectile dysfunction (ED) can be a sentinel marker for future cardiovascular disease and has been described as providing a "window of curability" for men to receive targeted cardiovascular risk assessment. AIM: To determine whether the prescription of phosphodiesterase type 5 inhibitors (PDE5is) for ED leads to the detection and treatment of previously undiagnosed cardiometabolic risk factors. METHODS: We performed a retrospective population-based cohort study of residents of British Columbia, Canada using linked health care databases from 2004 to 2011...

The value of snake venom polypeptides in clinical application has drawn extensive attention, and the development of snake polypeptides into new drugs with anti-tumor, anti-inflammatory, antithrombotic, analgesic or antihypertensive properties has become the recent research hotspot. With the rapid development of molecular biology and biotechnology, the mechanisms of snake venom polypeptides are also gradually clarified. Numerous studies have demonstrated that snake venom polypeptides exert their pharmacological effects by regulating ion channels, cell proliferation, apoptosis, intracellular signaling pathway, and expression of cytokine as well as binding to relevant active sites or receptors...

BACKGROUND: Metformin use reduces the incidence and severity of stroke in patients with type 2 diabetes mellitus (DM). The benefits of metformin for stroke have not been examined in hemodialysis patients with DM. METHODS AND RESULTS: Using the National Health Insurance Research Database, we identified 17 760 patients with DM and new-onset hemodialysis between 2001 and 2013. Of these, 1898 patients hospitalized for either ischemic or hemorrhagic stroke were matched to 7592 control patients according to sex, age, and year of initial hemodialysis therapy by using incidence sampling...

BACKGROUND: Metformin presents better survival rates than other oral antidiabetics in the treatment of type 2 diabetes. However, these benefits may be dampened by inadequate treatment adherence. OBJECTIVE: We aimed to investigate the relationship between adherence level to metformin therapy and all-cause mortality over 10 years in incident metformin users. METHODS: A nested case-control study was conducted using a large cohort of beneficiaries of the Quebec public drug insurance plan, aged 45 to 85 years, who initiated metformin between 2000 and 2009...

In many individuals, blood pressure varies between clinic visits conducted days, weeks, or months apart. This visit-to-visit variability (VVV) of blood pressure has been recently related with an increased risk of coronary heart disease, stroke, and mortality, independently of mean blood pressure. As for other chronical diseases, patients' adherence to hypertensive therapies remains low and partial adherence to antihypertensive treatment may constitute a source of VVV, as suggested by recent studies. This data should lead to a new clinical approach for hypertension care, based on patients' real adherence to treatment...

The results of pivotal trials, which provide a rationale for marketing approval decisions for new drugs, are considered for various comparative purposes in post-marketing analyses. Using meta-regression analysis of 91 randomized controlled trials of 61 approved antihypertensive drugs in Japan, we show that mean baseline blood pressure (BP) of each arm was associated with pre-determined entry criteria (EC), age, and trial start year (TSY). BP changes following treatment were associated with EC, subject characteristics (e...

New-onset diabetes mellitus (NOD) refers to forms of diabetes mellitus that develop during the therapeutic processes of other diseases such as hypertension. This study has been conducted in a network meta-analysis to compare antihypertensive drugs by identifying both the advantages and disadvantages on NOD by focusing on their respective effect rates. Odd ratios and corresponding 95% confidence intervals or credible intervals were calculated within pairwise and network meta-analysis. A total of 38 articles with 224 140 patients were included to evaluate the preventive effect of hypertension drugs on NOD...

BACKGROUND: Little is known about physicians' approaches to adopting new cardiovascular drugs and how adoption varies between drugs of differing novelty. METHODS: Using data on dispensed prescriptions from IMS Health's Xponent™ database, we created a cohort of all primary care physicians (PCPs) and cardiologists in Pennsylvania who regularly prescribed anticoagulants, antihypertensives and statins from 2007 to 2011. We examined prescribing of three new cardiovascular drugs of differing novelty: dabigatran, aliskiren and pitavastatin...

BACKGROUND: Research suggests antihypertensive medications are associated with fractures in older adults, however results are inconsistent and few have examined how the association varies over time. We sought to examine the association between antihypertensive class and incident non-vertebral fractures among older adults initiating monotherapy according to time since initiation. METHODS: We used a new-user cohort design to identify Medicare beneficiaries (≥ 65 years of age) initiating antihypertensive monotherapy during 2008-2011 using a 20% random sample of Fee-For-Service Medicare beneficiaries enrolled in parts A (inpatient services), B (outpatient services), and D (prescription medication) coverage...

The prevalence of type 2 diabetes mellitus (T2DM) increases worldwide, forcing for more research in the area of the optimal diabetes management. Cardiovascular disease (CVD) remains the commonest cause of death in individuals with T2DM. Besides hyperglycemia, an explanation for the increased mortality in this population is the increased prevalence of comorbidities, such as hypertension and dyslipidemia. Recent population-based studies described a prevalence of hypertension greater than 80% in patients with T2DM...
