Published Studies Related to Hydralazine

Hydralazine for essential hypertension. [2011.11.09]
CONCLUSIONS: Hydralazine may reduce blood pressure when compared to placebo in patients with primary hypertension, however this data is based on before and after studies, not RCTs. Furthermore, its effect on clinical outcomes remains uncertain.

Comparison of the efficacy of nifedipine and hydralazine in hypertensive crisis in pregnancy. [2011.11]
Intravenous hydralazine is a commonly administered arteriolar vasodilator that is effective for hypertensive emergencies associated with pregnancy...

Changes in fetal and maternal Doppler parameters observed during acute severe hypertension treatment with hydralazine or labetalol: a randomized controlled trial. [2011.01]
We evaluated 16 pregnant women with gestational age between 20 and 32 weeks in acute severe hypertension which were randomly allocated to receive either hydralazine or labetalol. Blood pressure and Doppler ultrasound parameters from maternal uterine and fetal middle cerebral and umbilical arteries were assessed during acute severe hypertension and after treatment...

A double-blind, placebo-controlled, randomized phase III trial of chemotherapy plus epigenetic therapy with hydralazine valproate for advanced cervical cancer. Preliminary results. [2010.10.08]
The reversing of epigenetic aberrations using the inhibitors of DNA methylation and histone deacetylases may have therapeutic value in cervical cancer... Molecular correlates with response and survival from this trial are pending to analyze.

Hydralazine for essential hypertension. [2010.08.04]
CONCLUSIONS: Hydralazine may reduce blood pressure when compared to placebo in patients with primary hypertension, however this data is based on before and after studies, not RCTs. Furthermore, its effect on clinical outcomes remains uncertain.

Clinical Trials Related to Hydralazine

Safety and Cardiovascular Efficacy of Hydralazine and Isosorbide Dinitrate in Dialysis-Dependent ESRD [Not yet recruiting]
This study is a pilot study designed to compare the safety and cardiovascular effects of 26 weeks of combination hydralazine/isorsorbide dinitrate therapy with amlodipine therapy in patients receiving chronic hemodialysis. The investigators hypothesize that treatment of chronic hemodialysis (ESRD) patients with a combination of hydralazine/isosorbide dinitrate compared with amlopdipine is safe and that it will improve heart function as well blood flow/blood vessel supply.

Bi Treatment With Hydralazine/Nitrates Versus Placebo in Africans Admitted With Acute Heart Failure [Active, not recruiting]
To investigate the effect of hydralazine isosorbide dinitrate on clinical outcomes, symptoms, cardiac parameters and functional status of African patients hospitalized with AHF and left ventricular dysfunction during 24 weeks of therapy. Administration of hydralazine/nitrates will be superior to placebo administration in reducing HF readmission or death, improving dyspnoea, reducing blood pressure and brain natriuretic peptide (BNP) in African patients admitted with AHF and left ventricular dysfunction.

Hydralazine Valproate for Ovarian Cancer [Recruiting]
The current standard for recurrent, persistent or metastatic cisplatin-resistant ovarian cancer is palliative chemotherapy with either topotecan, liposomal doxorubicin or gemcitabine, 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 topotecan over placebo plus topotecan upon progression-free survival. Hypothesis. Hydralazine and magnesium valproate associated to topotecan will increase progression-free survival from 6 to 9 months as compared with the same regimen of chemotherapy plus placebo.

Hydralazine as Demethylating Agent in Breast Cancer [Withdrawn]
This study will be conducted as a phase I/II clinical trial. In addition to determining the maximum tolerated dose (MTD) of hydralazine, the phase I trial will be performed to identify unexpected toxicities that may occur when hydralazine is used in conjunction with neoadjuvant chemotherapy in normotensive women with breast cancer. Once the phase I trial is successfully completed, the phase II trial to evaluate the efficacy of hydralazine in producing a demethylation effect will begin.

Hydralazine Versus Labetalol for the Management of Hypertensive Disorders of Pregnancy [Completed]
Hypertensive crisis (defined as a systolic pressure > 160mmHg or a diastolic pressure > 110mmHg) in patients with a hypertensive disorder of pregnancy is a serious complication with severe and even deadly consequences. The management in this population had been studied, but no consensus has been reached with regards to which treatment is better. Our study will compare two drugs: Hydralazine and Labetalol for the management of hypertensive crisis.
