TY - JOUR. T1 - Direct effects of hydralazine on cardiac contractile function, haemodynamics, and myocardial energetics in isolated myocardium. AU - Rendig, Stephen V.. AU - Segel, Leigh D.. AU - Amsterdam, Ezra A. PY - 1988/1/1. Y1 - 1988/1/1. N2 - The direct cardiac effects of hydralazine were studied in isolated working rat heart, isolated cat right ventricular papillary muscle, and isolated rabbit right atrium. The haemodynamics, myocardial energetics, and contractility of isolated hearts were measured at hydralazine concentrations of 0.01, 0.1, 0.5, 1.0, 10 and 100 μmol·litre-1. Coronary flow was significantly increased (≥21%, p,0.01) in paced (325 beats·min-1) rat hearts at ≥0.5 μmol·litre-1 hydralazine and in spontaneously beating hearts (≥37%; p,0.05) at ≥1.0 μmol·litre-1 hydralazine. The increases in coronary flow occurred without significant increases in heart rate, contractility (dP/dtmax), or coronary perfusion pressure. Myocardial oxygen consumption was not ...

Angiotensin I converting enzyme inhibitors are typically classified as peripheral vasodilators. We studied the effect of captopril and a known vasodilator, hydralazine, on arterial pressure-urinary output relationships in adult spontaneously hypertensive rats to determine whether these drugs produced similar changes in this relationship. Tail-cuff pressure and 24-hour urine output and sodium excretion were measured under steady state conditions during ingestion of tap water or saline (1% NaCl) ad libitum. Sodium intake increased seven to nine times when rats drank saline, but in the absence of drug treatment, tail-cuff pressure was not altered significantly (water, 213 +/- 3 vs saline, 220 +/- 5 mm Hg). Daily administration of captopril (100 mg/kg p.o.) or hydralazine (15 mg/kg p.o.) for 2 weeks lowered tail-cuff pressure significantly (175 +/- 3 and 166 +/- 3 mm Hg, respectively; p less than 0.01) while rats drank tap water. Continued administration of hydralazine plus 2 weeks of drinking ...

We studied the effect of hydralazine, an antihypertensive drug with lupus-inducing side effects, on the conformation of poly(dG-m5dC).poly(dG-m5dC) and a plasmid with a 23 bp insert of (dG-dC)n.(dG-dC)n sequences. Using an e.l.i.s.a. with a monoclonal anti-(Z-DNA) antibody Z22, we found that hydralazine provoked the Z-DNA conformation in poly(dG-m5dC).poly(dG-m5dC) at 250-500 microM concentration. The supercoiled form of hydralazine-treated plasmid bound to Z22 in a gel-retardation assay. To examine further whether Z-DNA could act as an inciting agent in anti-nuclear antibody production in patients, we analysed 65 sera from 25 hypertensive patients taking hydralazine and found anti-(Z-DNA) antibodies in 82% of these sera. Sera from age-matched normal controls showed no binding to Z-DNA. Data on sera drawn sequentially from four hypertensive patients showed that antibodies were present after the drug treatment. These data demonstrate the presence of a high incidence of anti-(Z-DNA) antibodies in ...

Methods We studied 20 patients with sHF who were undergoing elective coronary artery bypass surgery. All recruited patients were receiving optimal sHF therapy. Internal mammary artery (IMA) was available in 10 cases. Distal segments of left IMA and saphenous vein (SV), which were harvested at the time of surgery, were collected for use in vascular studies. Vasodilatation was examined using standard organ bath techniques; cumulative concentration response curves to hydralazine (1 nmol/l to 10 μmol/l) were constructed in vessels preconstricted with phenylephrine (3 μmol/l) and mantained in physiological conditions. Basal superoxide production was measured using lucigenin chemiluminescence in SV (n = 10) and IMA (n = 10) pre-incubated with hydralazine (1 μmol/l). A xanthine/xanthine oxidase system was used to quantify the data. Plasma concentrations of hydralazine are 0.1-1 μmol/l in patients taking therapeutic doses. ...

Hydrallazine (Apresoline - Ciba) first achieved popularity as an antihypertensive drug because of the belief that it would reduce diastolic blood pressure while increasing renal blood flow. In doses that can be tolerated, it has little antihypertensive effect in most patients; it increases peripheral blood flow by direct stimulation of the heart, which is often accompanied by myocardial ischaemia, and anginal attacks. It does not appear to improve impaired renal blood flow.. ...

The current standard for recurrent, persistent or metastatic cervical cancer is palliative chemotherapy with cisplatin topotecan, however, the results need to be improved. Epigenetic aberrations play an important role in cancer progression by silencing growth regulatory genes and there is now evidence that inhibitors of DNA methylation and HDAC inhibition synergize the cytotoxicity of chemotherapy.. Objective. To determine the superiority of epigenetic therapy with hydralazine and valproate plus standard cisplatin topotecan against placebo plus cisplatin topotecan upon progression-free survival.. Hypothesis. Hydralazine and magnesium valproate associated to cisplatin topotecan will increase progression-free survival from 4.6 to 7.6 months as compared with the same regimen of chemotherapy plus placebo. ...

Left ventricular (LV) hypertrophy is the structural adaptation of the heart in response to chronic LV pressure load. Studies in spontaneously hypertensive rats (SHR), which represent a model of genetically determined arterial hypertension, reveal that cardiac hypertrophy can be controlled by long-term blood pressure normalization with the use of various antihypertensive agents, such as arterial vasodilatators (hydralazine), converting enzyme inhibitors (captopril), beta-receptor blockers (metoprolol), antiadrenergic substances (alpha-methyldopa, guanethidine), and calcium antagonists (nifedipine, felodipine). Additional drug-specific effects modulate the mechanical effect of LV systolic unloading on cardiac hypertrophy: after a combined treatment with metoprolol and hydralazine, LV hypertrophy was quantitatively lower than after single hydralazine therapy, although blood pressure had been lowered to the same extent. LV collagen concentration remained unchanged when medical treatment prevented ...

BiDil or a combination of isosorbide dinitrate and hydralazine hydrochloride was studied in two placebo-controlled clinical trials in 1,692 patients with mild to severe heart failure (mostly NYHA class II and III) and one active control trial (vs. enalapril) in 804 patients. In the multicenter trial V-HeFT I, the combination of hydralazine and isosorbide dinitrate 75 mg/40 mg qid (n=186) was compared to placebo (n=273) in men with impaired cardiac function and reduced exercise tolerance (primarily NYHA class II and III), and on therapy with digitalis glycosides and diuretics. There was no overall significant difference in mortality between the two treatment groups. There was, however, a trend favoring hydralazine and isosorbide dinitrate, which on retrospective analysis, was attributable to an effect in blacks (n=128). Survival in white patients (n=324) was similar on placebo and the combination treatment. In a second study of mortality, V-HeFT II, the combination of hydralazine and isosorbide ...

Objective: To compare the efficacy and safety of intravenous dihydralazine with ketanserin in the management of severe hypertension in the third trimester. Study design: A double blind randomised controlled trial, comparing 5 mg dihydralazine with 10 mg ketanserin after an intravenous infusion of 500 ml of a crystalloid solution. Medication was repeated every 20 min till the therapeutic goal of 90 mm Hg was reached, to a maximum of 4 dosages. Main outcome measures were treatment failures and emergency deliveries for fetal distress. Results: The therapeutic goal was met more often in patients receiving dihydralazine (36/38 compared to 27/42; P,0.01). The need for delivery for fetal distress did not differ (3 after dihydralazine, 1 after ketanserin, P=0.29). No therapy related perinatal loss occurred, but one mother with an undiagnosed phaechromocytoma died 24 h after receiving dihydralazine. Conclusion: Ketanserin in this dosage is less effective to lower diastolic blood pressure. The place of a ...

Public Health: On Race-Based Therapeutics http://scienceweek.com/2004/sc041210-5.htm The following points are made by M. Gregg Bloche (New Engl. J. Med. 2004 351:2035): 1) Are we moving into a new era of race-based therapeutics? The recent publication of the African-American Heart Failure Trial (A-HeFT), a clinical trial of a medication intended for a single racial group, poses this awkward question. The studys most striking finding -- that the addition of isosorbide dinitrate and hydralazine to conventional therapy for heart failure reduced relative one-year mortality by 43 percent among blacks -- has provoked wide discussion. The trials sponsor, NitroMed, which holds a patent on the fixed-dose combination of isosorbide dinitrate and hydralazine that was used, posits that heart failure has a different pathophysiology in blacks than in whites, necessitating different treatment strategies.(1) 2) The reported 43 percent relative decrease in the rate of death due to heart failure among blacks is ...

Data suggest that the addition of hydralazine and isosorbide dinitrate to the therapeutic regimen of digoxin and diuretics in patients with chronic congestive heart failure can have a favorable effect on left ventricular function and mortality. (From Abstract). ...

In a double-blind, randomized crossover study, the daily administration of 30 to 90 mg of nifedipine lowered blood pressure in a dose-related fashion in 14 patients already taking a beta receptor blocker and diuretic. The duration of the hypotensive response to 20 mg of nifedipine in capsule form, giving as a step-three drug to five of these patients, was six to eight hours. A survey of 122 patients with resistant hypertension treated long-term with nifedipine and a control group of 102 similar patients treated with hydralazine revealed that nifedipine at an average dose of 40 mg daily caused a fall in blood pressure similar to that achieved with hydralazine in a dose of 86 mg daily. The side effect profile of both drugs was also similar. Nifedipine may be a useful alternative to existing step-three antihypertensive drugs.

Background Controversial effects of L-arginine-NO pathway have been shown on renal disease. The present study analyzes the main downstream of L-arginine-NO pathway, the NO-cGMP signaling in and the effect of the specific sGC stimulator Bay 41-2272 on the injury, matrix expansion and progression phases in the rat model of anti-thy1-induced renal disease. Methods The injection of anti-thy1 antibody into rats with two kidneys or nephrectomized rats caused a sequence of the injury, matrix expansion and progression phases. The effects of Bay 41-2272 (10 mg/kg body weight/d) treatment on systolic blood pressure, proteinuria, kidney function, glomerular and tubulointerstitial matrix protein accumulation, expression of TGF- beta1, fibronectin and PAI-1, macrophage infiltration, alpha1sGC and beta1sGC mRNA expression and basal and NO-stimulated renal cGMP production were determined. In the chronic anti-thy1 model, the effect of Bay 41-2272 was compared side-by-side to the sole vasodilator hydralazine (15 ...

Severe hypertension during pregnancy is a relevant health problem, particularly in developing countries. The review by Duley and Henderson-Smart compared different antihypertensive drugs with the aim of identifying those with the greatest comparative benefit and least risk for adverse outcomes. Strengths of the review include a clear statement of the objective and a comprehensive literature search without language restrictions. A limitation is data heterogeneity. Contributing factors to the data heterogeneity include different criteria for severe hypertension, doses, diagnoses, and outcome definitions. Hydralazine has been the first-line drug for decades and based on this systematic review, it will continue to be. Diazoxide causes a rapid decrease in blood pressure, and as expected, this systematic review shows some probable consequences, such as an increased number of maternal hypotension episodes and the need for cesarean section due to fetal distress. Although the initial use of hydralazine ...

Hydralazine, or 1-hydrazinylphthalazine, is a direct-acting smooth muscle relaxant used to treat hypertension by acting as a vasodilator, primarily in arteries and arterioles. Upon condensing with carbonyl compounds hydralazine will form hydrazones, namely 1-phthalazinyl hydrazones, which find use as vasodilating antihypertensive drugs and also application in optoelectronics (Caruso et al., 2005).. The title compound is one such 1-phthalazinyl hydrazone. It crystallizes in the triclinic, P1, space group. The molecule exists in its E configuration with respect to the C7=N1 bond which is confirmed by the torsion angle of 177.11 (12)° of the C6-C7-N1-N2 moiety (Fig. 1). The torsion angle of -5.33 (17)° of the N1-N2-C8-N3 moiety shows that the N1 and N3 atoms are cis to each other. The C7=N1 [1.2859 (16) Å] and C8=N2 [1.3010 (16) Å] bond distances are very close to the formal C=N bond length of reported similar compounds [C=N; 1.282 (4) and 1.288 (3) Å, respectively] (e.g., Shafiq et al., ...

BiDil, a combination of isosorbide dinitrate and hydralazine, was approved by the FDA in 2005 to treat heart failure in African Americans- the first race-based indication in the U.S. Though some groups lauded this move as a win for the underserved Black community, controversy soon emerged- and rightly so. Why did the researchers come to the conclusion that this combination of drugs worked better for one racial group than another? Why did the FDA take the action to approve it this way? The answers were not reassuring.. Did you know that there is no genetic basis for discrete racial categories? If not, this is likely because of what you were taught in training. Its time to unlearn some falsehoods! The concept of race is not, in fact, biological, but social. It is not race, but racism that creates and perpetuates inequities.. Race-based medicine is bad medicine. Period. Dorothy Roberts gave a seminal TED talk in 2015 explaining this concept. The persistent myths that characteristics like pain ...
