Evidence-Based Answer Adding an ACE inhibitor to standard therapy reduces total mortality and cardiovascular events. Adding an ARB also reduces cardiovascular events. Overall effects are modest. Current evidence does not support the use of ACE inhibitor and ARB combinations over ACE inhibitors alone, because the risk of adverse events increases without additional benefit. Evidence suggests that...

Because dopamine influences arginine vasopressin (AVP) release, the present studies were designed to ascertain the dopamine receptor subtype that potentiates angiotensin II-induced AVP secretion in cultured hypothalamo-neurohypophysial explants. Dopamine (a nonselective D1/D2 agonist), apomorphine (a D2 ≫ D1 agonist), and SKF-38393 (a selective D1 agonist) dose dependently increased AVP secreti...

Gagal jantung masih menjadi salah satu penyakit dengan angka mortalitas yang tinggi di seluruh dunia. Keterlibatan komorbiditas dan variasi etiologi dari ini merupakan tantangan bagi klinisi untuk melakukan pendekatan diagnosis serta penatalaksanaan pada gagal jantung. Klasifikasi itu sendiri terbagi tiga yaitu, Heart Failure with Preserved Ejection Fraction (HFpEF), Mildly Reduced (HFmrEF) (HF...

The renin-angiotensin system (RAS) has been traditionally linked to blood pressure and volume regulation mediated through the angiotensin II (ANG II) type 1 (AT1) receptor. Here we report that ANG II via its ANG II type 2 (AT2) receptor promotes the axonal elongation of postnatal rat retinal explants (postnatal day 11) and dorsal root ganglia neurons in vitro, and, moreover, axonal regeneration...

Fimasartan (Kanarb®), an angiotensin II receptor antagonist with selectivity for the AT1 receptor subtype, is a pyrimidinone-related heterocyclic compound that was developed by Boryung Pharm. Co., Ltd. Among numerous synthetic derivatives, fimasartan was chosen as a new drug candidate through in vitro and in vivo screening studies. Pharmadynamic-pharmacokinetic properties and safety profiles we...

The Gi pathway augments renal vasoconstriction induced by angiotensin II in spontaneously hypertensive but not normotensive Wistar-Kyoto rats. Because the Gi-coupled pancreatic polypeptide (PP)-fold peptide receptors Y1 and Y2 are expressed in kidneys and are activated by endogenous PP-fold peptides, we tested the hypothesis that these receptors regulate angiotensin II-induced renal vasoconstri...

The title compound, eprosartan mesylate {systematic name: 2-butyl-1-(4-carb-oxy-benz-yl)-5-[(E)-2-carb-oxy-3-(thio-phen-2-yl)prop-1-en-yl]-1H-imidazol-3-ium methane-sulfonate}, C(23)H(25)N(2)O(4)S(+)·CH(3)O(3)S(-), one of the angiotensin II-receptor antagonists, is effective in regulating hypertension, induced or exacerbated by angiotensin II, and in the treatment of congestive heart failure, r...

Angiotensin type 1 (AT1) receptor blocker (ARB) ameliorates progression of chronic kidney disease. Whether this protection is due solely to blockade of AT1, or whether diversion of angiotensin II from the AT1 to the available AT2 receptor, thus potentially enhancing AT2 receptor effects, is not known. We therefore investigated the role of AT2 receptor in ARB-induced treatment effects in chronic...

The release of arginine vasopressin (AVP) from the magnocellular neurosecretory cells (MNCs) in the supraoptic nucleus (SON) is crucial for body fluid homeostasis. The MNC activity is modulated by synaptic inputs and humoral factors. A recent study demonstrated that an N-terminal splice variant of the transient receptor potential vanilloid type 1 (TRPV1) is essential for osmosensory transductio...

Obesity is characterized by increased circulating levels of the adipocyte-derived hormone leptin, which can increase sympathetic nerve activity and raise blood pressure. A previous study revealed that rats fed a high-fat diet (HFD) have an enhanced hypertensive response to subsequent angiotensin II administration that is mediated at least, in part, by increased activity of brain renin-angiotens...
