Fatal hepatotoxicity induced by hydralazine or labetalol.
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...
متن کاملLabetalol-induced toxic myopathy.
Labetalol has been successful in treating hypertension, and few side effects have been reported, although there have been cases of muscle pain during treatment. A patient with essential hypertension treated with labetalol 600 mg daily complained of muscle pains, particularly in the legs. No neurological abnormality was found, but the activity of muscle enzymes in the blood was high. Findings on...
متن کاملDetermination of Total Urinary Catecholamines
SYNOPSIS Two patients with phaeochromocytoma having atypical biochemical features are described. Total catecholamine excretion was normal in one and only slightly raised in the other; both had a diagnostic rise in output of metadrenaline and 4-hydroxy-3-methoxymandelic acid whilst 4-hydroxy-3-methoxyphenylglycol excretion was increased in one of them. During hypertensive attacks adrenaline excr...
متن کاملLabetalol Prevents Intestinal Dysfunction Induced by Traumatic Brain Injury
BACKGROUND Beta-adrenergic blockade has been hypothesized to have a protective effect on intestinal dysfunction and increased intestinal permeability associated with the epinephrine surge after traumatic brain injury (TBI). METHODS Wister rats were subjected to either a weight drop TBI, and intraperitoneally injected or not with labetalol, or a sham procedure (18 rats per group). After 3, 6, ...
متن کاملSeparation of urinary catecholamines and catecholamine metabolites by high-pressure liquid chromatography.
A series of high-pressure liquid chromatographic (hplc) procedures are described for the separation of all major and most minor catecholamine metabolites present in human urine. The amines and metabolites are first concentrated and partially purified by traditional methods, ion-exchange and alumina chromatography. Final separations are then performed with hplc. Our system is specifically design...
