We examined the effects of angiotensin II (Ang II) and Ang-(1-7) on the release of [3H]norepinephrine elicited by nerve stimulation (2 Hz, 0.5 millisecond, for 2 minutes) in rat atria isolated with their cardioaccelerans nerves. The stimulation-induced release of [3H]norepinephrine was increased 50% by 3 x 10(-8) mol/L of either peptide. No further increase in [3H]norepinephrine release was obs...

      Losartan potassium is a well known orally active non-peptide angiotensin II receptor antagonist. Losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin II by selectively blocking the binding of angiotensin II to AT1 receptors. The drug is reported to promote the decrease in ventricular hypertrophy, salt ...

Fetal angiotensin II receptor antagonist exposure is associated with major complications and even death when administered during pregnancy. Neonates frequently require intensive care treatment, and mortality is high. Despite this well-known risk potential, a considerable number of women still receive angiotensin II receptor antagonists during pregnancy to treat arterial hypertension. Although c...

losartan potassium is a well known orally active non-peptide angiotensin ii receptor antagonist. losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin ii by selectively blocking the binding of angiotensin ii to at1 receptors. the drug is reported to promote the decrease in ventricular hypertrophy, salt and water excreti...

It is suggested that vasoconstriction mediated by angiotensin II cleaved from angiotensin I by angiotensin converting enzyme (ACE) is counterbalanced by concomitant formation of vasodilator angiotensin (1-7) by neutral endopeptidase (NEP). Here, we tested this hypothesis using as a bioassay the isolated rat lung perfused with Krebs-Henseleit (KH) solution and ventilated with negative pressures....

Blockade of the renin-angiotensin system with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers has become a crucial element in cardiovascular and renal medicine. This review evaluates the potential of renin inhibition as an adjunct to therapies that depend on renin system interruption.

materials and methods: 32 new zealand rabbits were randomly divided into three groups: control group, high-cholesterol group and losartan group. the level of weights, serum lipid levels and inflammatory factors, such as il-6 and hs c-reactive protein were detected before the losartan intervention and two months after the losartan intervention respectively. the content of angii was detected on l...

DESCRIPTION TEVETEN HCT 600/12.5 mg and TEVETEN HCT 600/25 mg (eprosartan mesylate­ hydrochlorothiazide) combine an angiotensin II receptor (AT1 subtype) antagonist and a diuretic, hydrochlorothiazide. TEVETEN (eprosartan mesylate) is a non-biphenyl non-tetrazole angiotensin II receptor (AT1) antagonist. A selective non-peptide molecule, TEVETEN is chemically described as the monomethanesulfona...

Coronaviruses (CoVs) are a group of viruses that induce infection in the respiratory and other systems in the human body. There are two coronaviruses that transmitted from animals to humans including severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS) (1). The novel coronavirus that appeared at first in Wuhan, China, in December 2019 was named as severe acut...

The aim of this study was to determine whether angiotensin receptor subtypes play a role in angiotensin clearance from plasma. Angiotensin metabolic clearance rate was measured in rats by the constant infusion method. Increasing doses of angiotensin II were infused for 15 minutes, and blood was sampled for angiotensin II. The type 1 angiotensin II receptor antagonist losartan decreased the appa...
