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...

Individualized prediction of the effect of angiotensin receptor inhibition on renal and cardiovascular outcomes in patients with diabetic nephropathy
Conclusions The combined effects of ARBs on ESRD and CVD and mortality in patients with diabetic nephropathy varies considerably between patients. A substantial proportion of patients remain at high risk for both outcomes despite ARB treatment.

Pattern of antihypertensive therapy among diabetic hyperten- sive patients in zewditu memorial hospital, addis ababa.
CONCLUSION: The pattern of antihypertensive drug therapy in our patients was consistent with the current treatment guidelines. However, the majority of diabetic-hypertensive patients did not reach target blood pressure. PMID: 27476227 [PubMed - in process]

Safety and Efficacy of Losartan/Hydrochlorothiazide Combination in Elderly Patients with Morning Hypertension: Mappy Study
Background: Cardiovascular events, such as stroke and myocardial infarction, occur most frequently in the morning. Morning hypertension is characteristic feature of hypertension in the elderly, and is attributed to hypertensive organ damage and cardiovascular events. However, treatment of morning hypertension has not been established, especially in the elderly patients. The aim of this study was to compare the safety and effectiveness between an an angiotensin II receptor blocker (ARB) / hydrochlorothiazide (HCTZ) combination therapy and high-dose ARB therapy in the elderly (75 years or more) and younger (less than 75 years) patients.

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 ...

Moderate salt restriction with or without paricalcitol in type 2 diabetes and losartan-resistant macroalbuminuria (PROCEED): a randomised, double-blind, placebo-controlled, crossover trial
This study is registered with ClinicalTrials.gov, number NCT01393808, and the European Union Clinical Trials Register, number 2011-001713-14. Findings Between Dec 13, 2011, and Feb 17, 2015, we randomly allocated 57 (50%) patients to a low-sodium diet (28 [49%] to paricalcitol then placebo and 29 [51%] to placebo then paricalcitol) and 58 (50%) to a high-sodium diet (29 [50%] to paricalcitol then placebo and 29 [50%] to placebo then paricalcitol). In the low-sodium group (30 mEq of daily sodium intake reduction, equivalent to approximately 1·7–1·8 g per day), 24 h albuminuria was reduced by 36·6% (95% CI 28·5–44·9...

Vasomodulatory effects of the angiotensin II type 1 receptor antagonist losartan on experimentally induced cerebral vasospasm after subarachnoid haemorrhage
ConclusionIn a physiological and pathophysiological setup, losartan reduces a PGF2-induced vasoconstriction and reverses a PGF2a-precontraction completely. This fact can be integrated in pushing forward further concepts trying to antagonise/prevent cerebral vasospasm after SAH.

Commonalities in epileptogenic processes from different acute brain insults: Do they translate?
Summary The most common forms of acquired epilepsies arise following acute brain insults such as traumatic brain injury, stroke, or central nervous system infections. Treatment is effective for only 60%‐70% of patients and remains symptomatic despite decades of effort to develop epilepsy prevention therapies. Recent preclinical efforts are focused on likely primary drivers of epileptogenesis, namely inflammation, neuron loss, plasticity, and circuit reorganization. This review suggests a path to identify neuronal and molecular targets for clinical testing of specific hypotheses about epileptogenesis and its prevention or...

Number and brightness analysis to study spatio-temporal distribution of the angiotensin II AT1 and the endothelin-1 ETA receptors: Influence of ligand binding
Publication date: Available online 6 March 2019Source: Biochimica et Biophysica Acta (BBA) - General SubjectsAuthor(s): Nadir Planes, Michelle A. Digman, Patrick P.M.L. Vanderheyden, Enrico Gratton, Catherina Caballero-GeorgeAbstractThe angiotensin II AT1 and the endothelin 1 ETA receptors play a crucial role in the pathogenesis of cardiovascular diseases like hypertension, heart failure, stroke, pulmonary hypertension, and cardiac hypertrophy. Both receptors are members of the rhodopsion-like superfamily of G protein-coupled receptors which can exist as monomers, dimers, and higher order aggregates.Recently, oligomerizati...

The holy grail of epilepsy prevention: preclinical approaches to antiepileptogenic treatments.
Abstract A variety of acute brain insults can induce epileptogenesis, a complex process that results in acquired epilepsy. Despite advances in understanding mechanisms of epileptogenesis, there is currently no approved treatment that prevents the development or progression of epilepsy in patients at risk. The current concept of epileptogenesis assumes a window of opportunity following acute brain insults that allows intervention with preventive treatment. Recent results suggest that injury-induced epileptogenesis can be a much more rapid process than previously thought, suggesting that the 'therapeutic window' may...
