Palliative care cancer patients are treated with many drugs especially at the end of life. Limiting of polypharmacy a decreases the risk of associated adverse effects, medical errors and harmful drug interactions The time lag to benefit of many medications used for cardiovascular diseases or risk factors like hypertension, hypercholesterolemia is frequently longer than palliative care cancer patient's life expectancy. It is ethically appropriate to modify, even to discontinue cardiovascular pharmacotherapy when there is no prospect of benefit...

The appropriate use of medications during Emergency Neurological Life Support (ENLS) is essential to optimize patient care. Important considerations when choosing the appropriate agent include the patient's organ function and medication allergies, potential adverse drug effects, drug interactions and critical illness and aging pathophysiologic changes. Critical medications used during ENLS include hyperosmolar therapy, anticonvulsants, antithrombotics, anticoagulant reversal and hemostatic agents, anti-shivering agents, neuromuscular blockers, antihypertensive agents, sedatives, vasopressors and inotropes, and antimicrobials...

Folic acid is generally used to lower homocysteine concentrations and prevent stroke and cardiovascular disease (CVD) at present. However, the efficacy of therapies that lower homocysteine concentrations in reducing the risk of CVD and stroke remains controversial. Our objective was to do a meta-analysis of relevant randomized controlled trials (RCTs) to evaluate the efficacy of folic acid supplementation among patients with hypertension and Hyperhomocysteinemia (HT/HHcy). We included RCTs examining the effects of folic acid plus antihypertensive therapy compared to antihypertensive alone...

PURPOSE: In recent years, the predictive value of 2 pulsatile parameters has been extensively studied in hypertension: aortic stiffness and pulse pressure (PP) amplification. Aortic stiffness is an index of aortic rigidity and PP-amplification is the ratio between central and brachial PP, an indirect evaluation of wave reflections. Both are safe, independent, noninvasive predictors of overall and cardiovascular risk. Our purpose is to determine the validity of these parameters in 2 different circumstances: gender and therapeutic implications...

Considering the high prevalence of hypertension among general population, the general practitioner is frequently challenged to start an antihypertensive therapy, which aims to lower blood pressure and to reduce the cardiovascular risk. At the initial stage, several critical questions must be asked : « Is a pharmacological treatment necessary ? », « Which are the target blood pressures ? » and « Which antihypertensive drug should be chosen to start therapy ? »The aim of this article is to give general practicioners some practical tools to guide them in the initial management of hypertensive patients...

INTRODUCTION: Several antihypertensive drugs are photosensitizing and may promote the development of malignant melanoma (MM), but evidence remains inconsistent. We sought to quantify the association between use of antihypertensive drugs and MM risk. METHODS: We systematically searched PubMed, Embase, and CENTRAL from inception to August 17, 2017 to identify observational studies that reported the MM risk associated with the use of antihypertensive drugs. A random-effects meta-analysis was used to estimate the odds ratio (OR) with 95% confidence interval (CI)...

BACKGROUND AND PURPOSE: Increased sympathetic tone causes hypertension after intracerebral hemorrhage, and blood pressure reduction has been studied as a way to decrease hemorrhage growth and improve outcomes. It is unknown if the antihypertensive used to achieve blood pressure goals influences either. Because sympatholytic drugs reduce death and infection in animal models, we hypothesized that labetalol would improve outcomes compared with nicardipine. METHODS: Prospective data from a single center were retrospectively reviewed...

The currently available antihypertensive agents have undesirable adverse effects due to systemically altering target activity including receptors, channels, and enzymes. These effects, such as loss of potassium ions induced by diuretics, bronchospasm by beta-blockers, constipation by Ca(2+) channel blockers, and dry cough by ACEI, lead to non-compliance with therapies (Moser, 1990). Here, based on new hypertension mechanisms, we explored a new antihypertensive approach. We report that transient receptor potential vanilloid 4 (TRPV4) interacts with Ca(2+)-activated potassium channel 3 (KCa2...

TEVAR is a less invasive option for managing traumatic injuries of the descending aorta in polytraumatized patients. Concerns arise when treating young patients with TEVAR. A 22-year old male was admitted to the Emergency Department following a high-impact road traffic collision. Whole body CT scan documented multiple injuries, including rupture of descending thoracic aorta just below the isthmus. There was no evidence of paraplegia or stroke. We decided to treat him in an endovascular fashion with a Zenith Cook (Cook Incorporated, Bloomington, IN) endograft...

Cleviprex is a short-acting dihydropyridine calcium channel antagonist used as an antihypertensive drug. In this work, the binding characterization of cleviprex to human serum albumin (HSA) and the competitive binding to HSA between cleviprex and two flavonoids, baicalin and rutin, were studied using multi-spectroscopic techniques and molecular docking method. The fluorescence quenching of HSA by cleviprex was initiated by the formation of HSA-cleviprex complex, which was confirmed by UV-vis spectra measurements...

An accurate assessment of drug safety or effectiveness in pharmaco-epidemiology requires defining an etiologically correct time-varying exposure model, which specifies how previous drug use affects the hazard of the event of interest. An additional challenge is to account for the multitude of mutually exclusive events that may be associated with the use of a given drug. To simultaneously address both challenges, we develop, and validate in simulations, a new approach that combines flexible modeling of the cumulative effects of time-varying exposures with competing risks methodology to separate the effects of the same drug exposure on different outcomes...

Hypertension is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease, stroke, peripheral artery disease and chronic renal insufficiency. Hypertensive heart disease can manifest as many cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in hypertensive patients, especially in those with left ventricular hypertrophy (LVH) or HF. Also, some of the antihypertensive drugs commonly used to reduce blood pressure, such as thiazide diuretics, may result in electrolyte abnormalities (e...

Since the discovery of WNK mutations causing an inherited form of hypertension in humans, there has been an increasing interest in targeting WNK-signaling as a novel strategy for modulating blood pressure. This notion is now supported by numerous mouse models with impaired WNK-signaling that exhibit reduced blood pressure. Biochemical analyses of the different protein components making up this signaling pathway have identified a number of plausible molecular targets that are amenable to targeting by small molecules...

Despite the availability of anti-hypertensive medications with proven efficacy and good tolerability, many hypertensive patients have blood pressure levels(BP) not at the goals set by international societies. Some of these patients are either non-adherent to the prescribed drugs or not optimally treated. However, a proportion, despite adequate treatment, has resistant hypertension(RH) defined as office BP above goal despite the use of ≥3 antihypertensive medications at maximally tolerated doses (one ideally being a diuretic)...

BACKGROUND: Hypertension is a risk factor for coronary heart disease and stroke, and is one of the leading causes of death. Although over a billion people are affected worldwide, only half of them receive adequate treatment. Current guidelines on antihypertensive treatment recommend combination therapy for patients not responding to monotherapy, but as the number of pills increase, patient compliance tends to decrease. As a result, fixed-dose combination drugs with different antihypertensive agents have been developed and widely used in recent years...

OBJECTIVE: There is little evidence to support an increased risk of blood pressure (BP) elevation among elderly individuals receiving antihypertensive drug treatment. METHODS: To clarify the impact on BP level and residual cardiovascular risk in treated elderly individuals, we analysed individual participant data of 26 133 residents aged 60-89 years from seven Japanese general populations and cross-classified participants by age category, 60-74 (young-old) versus 75-89 years (old-old), and by usage of antihypertensive medication at baseline survey (1980-1995)...

Tom L Blundell
The development of structure-guided drug discovery is a story of knowledge exchange where new ideas originate from all parts of the research ecosystem. Dorothy Crowfoot Hodgkin obtained insulin from Boots Pure Drug Company in the 1930s and insulin crystallization was optimized in the company Novo in the 1950s, allowing the structure to be determined at Oxford University. The structure of renin was developed in academia, on this occasion in London, in response to a need to develop antihypertensives in pharma...
