Sudden withdrawal of oral therapy with hydralazine for reduction of afterload in a patient precipitated severe congestive heart failure. Signs of metabolic encephalopathy evolved due to low cardiac output. Reinstitution of therapy with hydralazine resulted in prompt improvement in cardiac and neurologic status. This case underscores the need for careful follow-up of such patients and argues aga...

or apparent renal hypertension were studied following combined Rauwolfia-hydrialazine therapy. Adequate persistent lowering occurred in most instances of mild or moderate, and frequently even severe, hypertension. Prior and concomitant administration of Rauwolfia largely prevented unpleasant effects of hydralazine, permitted smaller dosage and ease of administration and follow-up often impossib...

The purpose of this study was to test the hypothesis that endogenous adenosine functions to restrain the renin release response to pharmacological and pathophysiological stimuli. To achieve this objective, we examined the effects of an adenosine receptor antagonist, 1,3-dipropyl-8-(p-sulfophenyl)xanthine (DPSPX), on the renin release response induced by acute administration of hydralazine or by...

The case is reported of a man developing drug-induced systemic lupus erythematosus while taking hydralazine. The illness was characterized by arthritis and a purpuric rash particularly in the light-sensitive areas as well as orogenital and cutaneous ulceration. Anti-nuclear antibody and DNA binding were positive. All clinical manifestations disappeared on withdrawal of hydralazine.

Neonatal sympathectomy reduces arterial pressure in spontaneously hypertensive rats (SHR). In SHR transplanted with a kidney from sympathectomized SHR, arterial pressure was lower and less Na+ sensitive than in SHR transplanted with a kidney from hydralazine-treated SHR. This study was performed to identify underlying renal mechanisms. Tests for differential renal mRNA expression of nine a prio...

OBJECTIVE To review outcomes in randomised controlled trials comparing hydralazine against other antihypertensives for severe hypertension in pregnancy. STUDY DESIGN Meta-analysis of randomised controlled trials (published between 1966 and September 2002) of short acting antihypertensives for severe hypertension in pregnancy. Independent data abstraction by two reviewers. Data were entered in...

Toxic carbonyls such as acrolein participate in many degenerative diseases. Although the nucleophilic vasodilatory drug hydralazine readily traps such species under "test-tube" conditions, whether these reactions adequately explain its efficacy in animal models of carbonyl-mediated disease is uncertain. We have previously shown that hydralazine attacks carbonyl-adducted proteins in an "adduct-t...

BACKGROUND AND PURPOSE The precise mechanism of salt-induced brain injury is unclear. We examined the detailed causative role of angiotensin II and NADPH oxidase in salt-accelerated brain injury of stroke-prone spontaneously hypertensive rats (SHRSP). METHODS We examined the effect of salt loading on brain reactive oxygen species (ROS), inflammation, and apoptosis in SHRSP. Salt-loaded SHRSP ...

Tsukuba hypertensive mice (THMs) are transgenic mice carrying human renin and angiotensinogen genes. The aim of this study was to evaluate the role of the renin-angiotensin system (RAS) in cardiac hypertrophy and renal disorders in THMs. After a 2-wk control period, 10-wk-old THMs were treated with lisinopril (ACEI group) or hydralazine (hydralazine group) or left untreated (control group) for ...
