Norepinephrine

Norepinephrine Injectable Solution [levophed]


Presentation

  • Subjects with a C allele in the SLC6A2 rs2242446 SNP presented higher elevations of the heart rate after MDMA administration compared with the TT genotype.[ncbi.nlm.nih.gov]
  • At presentation, the 22 patients with TS were 11 to 82years of age (mean age 49.9 20years). Seventeen of 21 (81%) of the patients were women. The most common presenting symptom was chest pain, which occurred in 59% of cases.[ncbi.nlm.nih.gov]
  • Correspondingly, the norepinephrine-synthesizing enzymes were present in the tumor tissue and tyrosine hydroxylase was found in amounts substantially higher than the levels normally present in adrenal medullary cells.[ncbi.nlm.nih.gov]
  • We present a case study of a patient with pure autonomic failure who was successfully treated with ambulatory norepinephrine (NE) infusions over a 9-year-period of time before death occurred unexpectedly.[ncbi.nlm.nih.gov]
  • A case of retroperitoneal leiomyosarcoma (LMS) in a 38-year-old woman who had a tumor in the retroperitoneum with severe hypertension and hypokalemia is presented.[ncbi.nlm.nih.gov]
Pallor
  • These may be accompanied by violent headache, photophobia, retrosternal pain, pallor, intense sweating and vomiting. In the event of overdosage, treatment should be withdrawn and appropriate corrective treatment initiated.[medicines.org.uk]

Intravenous Administration
  • Circulating ANG II modulates peripheral sympathetic nerve activity by acting on the area postrema, since ablation of this brain area prevents hypertension caused by chronic intravenous administration of ANG II.[doi.org]
Wound Infection
  • The primary endpoint was a composite of mortality or severe complications (stroke, requirement for mechanical ventilation for longer than 48 h, deep sternal wound infection, reoperation, or acute renal failure) within 30 days.[ncbi.nlm.nih.gov]
Periodontitis
  • Biological effects of the stress hormones on the anaerobes may range from halitosis and a worsening of periodontal diseases to tissue damages and atherosclerotic plaque ruptures.[ncbi.nlm.nih.gov]
Halitosis
  • Biological effects of the stress hormones on the anaerobes may range from halitosis and a worsening of periodontal diseases to tissue damages and atherosclerotic plaque ruptures.[ncbi.nlm.nih.gov]
Hypertension
  • In both patients, improvement in vision began within minutes after moderate hypertension was produced.[ncbi.nlm.nih.gov]
  • The feasibility of differentiating patients with pheochromocytoma from other hypertensive patients by measuring urinary excretion rates of norepinephrine during sleep, a period of physiologic suppression of norepinephrine release, was investigated.[ncbi.nlm.nih.gov]
  • Only five of 60 "sick" patients (8%) without a history of hypertension had elevated platelet norepinephrine concentration.[ncbi.nlm.nih.gov]

  • Optokinetic nystagmus quick phases decreased in velocity by 15   17%. These differences were statistically significant (p[ncbi.nlm.nih.gov]

Workup

Clostridium Perfringens
  • ., Tanerella forsythia and Propionibacterium acnes and can increase virulence gene expression, iron acquisition and many virulence factors of some anaerobic species such as Clostridium perfringens, Porphyromonas gingivalis and Brachyspira pilosicoli.[ncbi.nlm.nih.gov]

Treatment

  • During the treatments, the norepinephrine-dosage could be significantly reduced while mean arterial pressure was stable.[ncbi.nlm.nih.gov]
  • The primary outcome was the duration of norepinephrine treatment.[ncbi.nlm.nih.gov]
  • Given this patient's response to the NE infusion treatment, we discuss the option of ambulatory NE infusions as a treatment for severe orthostatic hypotension that is refractory to common treatments.[ncbi.nlm.nih.gov]
  • The study was divided into three treatment arms. Each group consisted of eight subjects on active treatment and two or three subjects on placebo. The CSF was sampled for 32 h using an intrathecal catheter.[ncbi.nlm.nih.gov]
  • A continuous ambulatory treatment with catecholamines could be a possible treatment - at least temporarily - in amyloid cases in which all other attempts have failed to prevent chronic life-threatening hypotension.[ncbi.nlm.nih.gov]

Pathophysiology

  • Although, the precise pathophysiology of Takotsubo cardiomyopathy is still unknown, it seems that it is associated with excessive sympathetic stimulation, microvascular dysfunction, coronary artery vasospasm, and abnormal myocardial tissue metabolism.[ncbi.nlm.nih.gov]
  • We provide a short overview of the current understanding of the immunologic pathophysiology of sepsis, followed by a detailed description of the immunomodulatory effects of norepinephrine and alternative vasopressors.[ncbi.nlm.nih.gov]
  • We tested the hypothesis that impaired functioning of the norepinephrine transporter contributes to the pathophysiologic mechanism of orthostatic intolerance.[ncbi.nlm.nih.gov]
  • The pathophysiology of POTS is complicated and poorly understood. Plasma norepinephrine (NE) is often elevated in patients with POTS, resulting in consideration of dysfunction of the norepinephrine transporter (NET) encoded by SLC6A2 gene.[ncbi.nlm.nih.gov]
  • Aerobic glycolysis is a widespread phenomenon that underlies energetics of diverse brain activities, such as alerting, sensory processing, cognition, memory, and pathophysiological conditions, but specific cellular functions fulfilled by aerobic glycolysis[ncbi.nlm.nih.gov]

Prevention

  • The use of norepinephrine to prevent and treat hypotension during CD is new, and its use as a bolus has not been fully determined in this context.[ncbi.nlm.nih.gov]
  • Importantly, both dopamine reuptake inhibition and norepinephrine reuptake inhibition prevented fatigue-related decrements in the peak velocity of prosaccades.[ncbi.nlm.nih.gov]
  • A continuous ambulatory treatment with catecholamines could be a possible treatment - at least temporarily - in amyloid cases in which all other attempts have failed to prevent chronic life-threatening hypotension.[ncbi.nlm.nih.gov]
  • DHPG metabolism is inhibited by the monoamine oxidase inhibitor, pargyline which prevents the deamination of norepinephrine, and by the aldose reductase inhibitor AL 1576, which inhibits DHPG formation without affecting the deamination of norepinephrine[ncbi.nlm.nih.gov]
  • Interestingly, the detrimental impact of fatigue on oculomotor control can be prevented by a moderate dose of caffeine. This effect may be related to central catecholamine upregulation via caffeine's action as an adenosine antagonist.[ncbi.nlm.nih.gov]
