Early treatment with losartan effectively ameliorates hypertension and improves vascular remodeling and function in a prehypertensive rat model
This study investigated 1) whether early treatment with either losartan or amlodipine at the onset of prehypertension can prevent hypertension and 2) whether losartan and amlodipine equally improve vascular remodeling and function in a rat model of hypertension. Materials and methods Stroke-prone spontaneously hypertensive (SHRSP) rats were administered losartan, amlodipine or saline for 6 or 16weeks at the onset of prehypertension. Wistar-Kyoto rats were used as a control. All groups were observed for 40weeks. Systolic blood pressure was measured using the tail-cuff method. Vascular structure and function were determined ...

Fimasartan: A New Angiotensin Receptor Blocker
Abstract Fimasartan is the ninth, and most recent, angiotensin II receptor antagonist approved as an antihypertensive agent. Fimasartan, a pyrimidin-4(3H)-one derivative of losartan with the imidazole ring replaced, which enables higher potency and longer duration than losartan. Fecal elimination and biliary excretion are the predominant elimination pathways of fimasartan and the urinary excretion was found to be less than 3 % 24 h after administration. Fimasartan is primarily catabolized by cytochrome P450 isoform 3A and no significant drug interaction was observed when used in combination with hydrochlorothia...

No evidence for a J-shaped curve in treated hypertensive patients with increased cardiovascular risk: The VALUE trial.
In conclusion, patients in BP strata ≥ 150/90 mmHg, but not patients in BP strata < 130/70 mmHg, were at increased risk for adverse outcomes in this hypertensive, high-risk population. Although benefit in preventing MI in relation to preventing stroke levels off for the lowest BPs, these data provide no support for a J-curve in the treatment of high-risk hypertensive patients . The increase in the ratio of MI to stroke with lower DBP indicates target organ heterogeneity in that the optimal on-treatment DBP for cerebroprotection is below that for cardioprotection.

Risks of Adverse Events Following Coprescription of Statins and Calcium Channel Blockers: A Nationwide Population-Based Study
In this study, 5857 patients received coprescription of CYP3A4-metabolized statins and CCBs that inhibit CYP3A4. There were no differences in comorbidity or use of antihypertensive drugs between patients who received CYP3A4-metabolized statins and those who received non-CYP3A4-metabolized statins. Patients who received CYP3A4-metabolized statins had significantly higher risk of acute kidney injury (adjusted odds ratio [OR] = 2.12; 95% CI = 1.35–3.35), hyperkalemia (adjusted OR = 2.94; 95% CI = 1.36–6.35), acute myocardial infarction (adjusted OR = 1.55; 95% CI = 1.16–2.07), and acute ischemic ...

Prehypertensive treatment with losartan, however not amlodipine, leads to long‑term effects on blood pressure and reduces the risk of stroke in spontaneously hypertensive stroke‑prone rats.
Authors: Zhang L, He D, Lin J Abstract The current study investigated the efficacy of losartan and amlodipine in protecting spontaneously hypertensive stroke‑prone (SHRSP) rats against the risk of stroke. SHRSP rats were administered losartan, amlodipine or the vehicle for 6 weeks. There were no significant differences in systolic blood pressure (SBP) in rats treated with losartan or amlodipine, however, following drug withdrawal, rats treated with losartan maintained reduced SBP for a longer time compared with rats treated with amlodipine. In addition, rats treated with losartan exhibited thinner vascular walls...

Therapy with the Combination of Amlodipine and Irbesartan Has Persistent Preventative Effects on Stroke Onset Associated with BDNF Preservation on Cerebral Vessels in Hypertensive Rats
In this study, we investigated the significant beneficial effects of the combination therapy using amlodipine and irbesartan against stroke onset in hypertensive rats. The animals were fed an 8 % sodium diet and assigned to (1) vehicle, (2) amlodipine (2 mg/kg/day), (3) irbesartan (20 mg/kg/day), and (4) amlodipine + irbesartan groups. The drugs were given orally until 35 days, and incidences of stroke-related signs and mortality and blood pressure (BP) were monitored. Cerebral blood flow (CBF), brain water content, weight of the brain and left ventricle, and histological evaluations were conducted for the treated grou...

Amlodipine+Benazepril is Superior to Hydrochlorothiazide+Benazepril Irrespective of Baseline Pulse Pressure: Subanalysis of the ACCOMPLISH Trial
Pulse pressure (PP) is an independent risk factor for cardiovascular (CV) disease and death but few studies have investigated the effect of antihypertensive treatments in relation to PP levels before treatment. The Avoiding Cardiovascular Events Through Combination Therapy in Patients Living With Systolic Hypertension (ACCOMPLISH) trial showed that the combination of benazepril+amlodipine (B+A) is superior to benazepril+hydrochlorothiazide (B+H) in reducing CV events. We aimed to investigate whether the treatment effects in the ACCOMPLISH trial were dependent on baseline PP. High‐risk hypertensive patients (n=11,499) wer...

A Cost Utility Analysis of Amlodipine Compared with Angiotensin II Receptor Blockers in Preventing Stroke and Myocardial Infarction Among Hypertension Patients in the Philippines
Hypertension represents a major health problem, affecting more than 21% of adults in the Philippines. Amlodipine, a calcium channel blocker, is considered to have better tolerance and effectiveness than other classes of antihypertensive treatments. Limited studies have examined the cost-effectiveness of Amlodipine in the Philippines. The purpose of this study was to compare the costs and effectiveness associated with Amlodipine and Angiotensin II Receptor Blockers (Valsartan) in preventing stroke and myocardial infarction (MI) among Filipino hypertension patients.

Pharmacogenetic effects of ‘candidate gene complexes’ on stroke in the GenHAT study
ObjectiveThe aim of this study was to investigate whether there is a genotype-by-treatment interaction in patients experiencing stroke and treated with one of three antihypertensive drugs, that is chlorthalidone, amlodipine, or lisinopril. Participants and methodsA population of 436 African Americans and 539 whites who had experienced stroke in the GenHAT study were genotyped for 768 single nucleotide polymorphisms (SNPs) in 280 candidate genes. To detect a genotype-by-treatment interaction, we used the Pearson’s χ2-test to assess whether the genotype frequencies differed at the single SNP level for the three drug treat...

The Value of N-Terminal Pro-B-Type Natriuretic Peptide in Determining Antihypertensive Benefit: Observations From the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT) Natriuretic Peptides
We investigated 3 hypotheses: (1) N-terminal pro–B-type natriuretic peptide (NT-proBNP) predicts cardiovascular disease events in patients with hypertension, (2) NT-proBNP is associated with blood pressure variability, and (3) NT-proBNP predicts benefit from antihypertensive regimens. The Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT) randomized a subset of 6549 patients at risk with no history of coronary heart disease to either atenolol-based or amlodipine-based blood pressure–lowering treatment. During 5.5 years of follow-up, 485 cardiovascular disease cases accrued and were matched with 1367 controls. Ba...

Long-term prehypertension treatment with losartan effectively prevents brain damage and stroke in stroke-prone spontaneously hypertensive rats.
Abstract Prehypertension has been associated with adverse cerebrovascular events and brain damage. The aims of this study were to investigate ⅰ) whether short‑ and long-term treatments with losartan or amlodipine for prehypertension were able to prevent blood pressure (BP)-linked brain damage, and ⅱ) whether there is a difference in the effectiveness of treatment with losartan and amlodipine in protecting BP-linked brain damage. In the present study, prehypertensive treatment with losartan and amlodipine (6 and 16 weeks treatment with each drug) was performed on 4-week‑old stroke-prone spontaneously hypert...
