Reports on the effectiveness of endothelin receptor blockers in angiotensin (Ang) II-induced end-organ damage are conflicting, and the mechanisms involved are uncertain. We tested the hypothesis that endothelin (ET)(A/B) receptor blockade with bosentan (100 mg/kg by gavage after age 4 weeks) ameliorates cardiac and renal damage by decreasing inflammation in rats harboring both human renin and a...
The oxidative metabolism of hydralazine, isoniazid, iproniazid, and phenylhydrazine has been studied using spin-trapping techniques. The oxidation of these hydrazine derivatives, catalyzed by horseradish peroxidase and prostaglandin synthetase, produces reactive free radical intermediates. Enzymatic activation of hydralazine produce the nitrogen-centered hydralazyl radical (RNHNH.); phenylhydra...
Hydralazine has been used since the 1950s for the management of hypertension. Evidence for hydralazine-associated vasculitis dates to pre-ANCA (antineutrophil cytoplasmic antibodies) era. This abstract describes two cases of ANCA-positive pauci-immune glomerulonephritis (GN) in challenging scenarios where diagnosis was misconstrued. A comprehensive literature review was done to understand the p...
The current study involves development of oral bioadhesive hydrophilic matrices of hydralazine hydrochloride, and optimization of their in vitro drug release profile and ex vivo bioadhesion against porcine gastric mucosa. A 32 central composite design was employed to systematically optimize the drug delivery formulations containing two polymers, viz., carbomer and hydroxypropyl methyl cellulose...
Antihypertensive agents have been associated with adverse reactions that, if unrecognized by health practitioners, may have devastating consequences. The pattern of hepatotoxicity observed during therapy with the vasodilator hydralazine is highly variable, often making its diagnosis difficult. Serious hepatic injury induced by the alpha- and beta-adrenergic receptor antagonist labetalol has onl...
The capacity of the vasodilating drugs, minoxidil and hydralazine, for inducing renin release was characterized in rats according to chronology and dose response. Propranolol inhibition of this renin release was also characterized and related to serum levels of propranolol. Minoxidil and hydralazine (1.0 mg/kg) induced sevenfold elevations of serum renin activity. Treatment with propranolol, re...
