Valsartan with amlodipine

The burden of cardiovascular disease (CVD) is rising in Kenya and non-adherence to cardiovascular pharmacotherapy is a growing global public health issue that leads to treatment failure, an increased risk of cardiac events and poor clinical outcomes. This study assessed adherence to selected cardiovascular therapy medications among CVD patients attending outpatient clinics at Kenyatta National Hospital, Kenya by determining drug concentration(s) in patient dried blood spot (DBS) samples. Patients who had been taking one or more of the five commonly prescribed CVD medications (amlodipine, atenolol, atorvastatin, losartan, and valsartan) for at least six months were enrolled...

Backround: The effect of antihypertensive drugs on glucose homeostasis and insulin resistance remains an issue under investigation. There is evidence that renin-angiotensin system (RAS) blockers may favorably affect glucose metabolism, while treatment with calcium channel blockers (CCBs) is considered to have an overall neutral metabolic effect. However, the effects on glycemic indices may differ among agents within the same class of antihypertensive drugs. Objective: To evaluate the effects of different fixed-dose single pill combinations of RAS blockers with CCBs on homeostatic model assessment for insulin resistance (HOMA-IR)...

High fructose intake has been implicated in obesity and metabolic syndrome, which are related to increased cardiovascular mortality. However, few studies have experimentally examined the role of renin-angiotensin system blockers and calcium channel blockers (CCB) in obesity. We investigated the effects of valsartan (an angiotensin II receptor blocker) and amlodipine (a CCB) on lipolysis through the potential mechanism of PU.1 inhibition. We observed that high fructose concentrations significantly increased adipose size and triglyceride, monoacylglycerol lipase, adipose triglyceride lipase, and stearoyl-CoA desaturase-1 (SCD1), activating transcription factor 3 and PU...

OBJECTIVE: Aim of this study was to evaluate dynamics of arterial stiffness using cardio-vascular index (CAVI), of the fixed triple combination of valsartan / amlodipine / hydrochlorothiazide and a double fixed combination of valsartan / amlodipine in the treatment of patients with arterial hypertension II-III degree depends on added statin therapy. DESIGN AND METHOD: The study included patients with moderate and severe arterial hypertension without diabetes. Patients were divided into 2 groups...

OBJECTIVE: Chemical Adherence Testing (CAT) is now the preferred method for assessing adherence with prescribed medication. Further research is needed to understand the impact of pharmacokinetics(PK) on medication detection and adherence status, but there is no readily available collated literature. This study aims to collate PK data for 20 of the most prescribed antihypertensive medications. DESIGN AND METHOD: Prescription rates were determined by reviewing CAT data of 3796 unselected hypertension patients whose samples were tested by the Department of Chemical Pathology & Metabolic Diseases, University Hospitals of Leicester NHS Trust...

OBJECTIVE: Hypertension and hyper-cholesterolaemia is a dangerous combination frequently found in clinical practice.

Methods: A total of 82 elderly patients with type H hypertension who were admitted to our hospital from March to August 2017 were selected as the research subjects. The study included a 4-week continuous irrigation period followed by a 24-week randomized treatment period...

We developed three ultra-high pressure liquid chromatography coupled to mass spectrometry detection (UHPLC-MS/MS) methods to quantify 25 antihypertensive drugs in serum samples. Patient-reported drug lists were collected, and drug concentrations were analysed in samples from 547 patients, half with uncontrolled hypertension, and all treated with ≥ 2 antihypertensive drugs. For sample preparation, serum was mixed with deuterated internal standards and acetonitrile and precipitated. Aliquots of the supernatant were injected on UHPLC-MSMS with a C18 reversed phase column...

Recent studies have reported that using certain antihypertensive therapies such as angiotensin II receptor blockers (ARBs) and calcium channel blocker (CCBs) is associated with reduction of fatal outcomes and improving clinical characteristics of patients suffering from hypertension during coronavirus pandemic. Thus, in the current work an effective, innovative and eco-friendly spectrophotometric manner namely, parent spectrum extraction (PSE)was established for evaluation of recommended triple antihypertensive combination therapies incorporate valsartan (VAL) as ARBs, amlodipine besylate as CCBs (AML) and hydrochlorothiazide (HCT)as diuretic into single-pill in challengeable ratio...

BACKGROUND: DPP4 (dipeptidyl peptidase-4) inhibitors comprise a class of oral diabetes medication that have the potential for off-target cardiovascular effects. We previously showed that DPP4 inhibition attenuates the hypotensive effect of acute ACE (angiotensin-converting enzyme) inhibition and increases norepinephrine. Here, we investigated the effects of DPP4 during sustained ACE inhibition compared with during therapy with an ARB (angiotensin receptor blocker) or calcium channel blocker (neutral comparator) in a randomized, double-blinded crossover study...

Nitrosamine contamination of generic valsartan was found in 2018. This study aimed to investigate whether long-term use of valsartan increases cancer risk. Patients prescribed valsartan or amlodipine (control group) from 1 January 1, 2003, to June 30, 2010, were identified using the Clinical Data Analysis and Reporting System of the Hong Kong Hospital Authority, a territory-wide database in Hong Kong. Patients previously diagnosed with cancer, prescribed both medications, taking the medication, or followed up for <1 year were excluded...

This study evaluates the therapeutic potentials of selected antihypertensive drugs [valsartan, amlodipine, lisinopril and their fixed-dose combinations (amlodipine + lisinopril) and (valsartan + lisinopril)] in ameliorating trastuzumab (TZM)‑induced cardiac dysfunctions in experimental rats. After an ethical clearance for the study was obtained, in-bred young adult female Wistar rats were randomly allotted into 10 groups of 6 rats per group. Group I rats were treated with 10 ml/kg/day sterile water p.o. and 1 ml/kg/day sterile water i...

Volumetric absorptive microsampling (VAMS), an emerging microsampling technique, is expected to overcome some disadvantages of dried blood spots.
