Dược Lực Học :
Noradrenaline acts on both alpha-1 and alpha-2 adrenergic receptors to cause vasoconstriction. Its effect in-vitro is often limited to the increasing of blood pressure through antagonising alpha-1 and alpha-2 receptors and causing a resultant increase in systemic vascular resistance.
Cơ Chế Tác Dụng :
Precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic. [PubChem]
Norepinephrine functions as a peripheral vasoconstrictor by acting on alpha-adrenergic receptors. It is also an inotropic stimulator of the heart and dilator of coronary arteries as a result of it's activity at the beta-adrenergic receptors.
Độc Tính :
In high dose and especially when it is combined with other vasopressors, it can lead to limb ischemia and limb death.
Chỉ Định :
Mainly used to treat patients in vasodilatory shock states such as septic shock and neurogenic shock and has shown a survival benefit over dopamine. Also used as a vasopressor medication for patients with critical hypotension.
Tương Tác Thuốc :
-
Amitriptyline
The tricyclic antidepressant, amitriptyline, increases the sympathomimetic effect of norepinephrine.
-
Amoxapine
The tricyclic antidepressant, amoxapine, increases the sympathomimetic effect of norepinephrine.
-
Clomipramine
The tricyclic antidepressant, clomipramine, increases the sympathomimetic effect of norepinephrine.
-
Desipramine
The tricyclic antidepressant, desipramine, increases the sympathomimetic effect of norepinephrine.
-
Desvenlafaxine
Desvenlafaxine may increase the tachycardic and vasopressor effects of norepinephrine. Consider alternate therapy or monitor for increased sympathomimetic effects, such as increased blood pressure, chest pain and headache.
-
Doxepin
The tricyclic antidepressant, doxepin, increases the sympathomimetic effect of norepinephrine.
-
Entacapone
Entacapone increases the effect and toxicity of the sympathomimetic, norepinephrine.
-
Guanethidine
Norepinephrine may decrease the effect of guanethidine.
-
Imipramine
The tricyclic antidepressant, imipramine, increases the sympathomimetic effect of norepinephrine.
-
Isocarboxazid
Increased arterial pressure
-
Linezolid
Possible increase of arterial pressure
-
Methyldopa
Increased arterial pressure
-
Midodrine
Increased arterial pressure
-
Moclobemide
Moclobemide increases the sympathomimetic effect of norepinephrine.
-
Nortriptyline
The tricyclic antidepressant, nortriptyline, increases the sympathomimetic effect of norepinephrine.
-
Phenelzine
Increased arterial pressure
-
Rasagiline
Increased arterial pressure
-
Reserpine
Increased arterial pressure
-
Trimipramine
Trimipramine may increase the vasopressor effect of the direct-acting alpha-/beta-agonist, Norepinephrine. Avoid combination if possible. Monitor sympathetic response to therapy if used concomitantly.
-
Venlafaxine
Venlafaxine may increase the tachycardic and vasopressor effects of Norepinephrine. Consider alternate therapy or monitor for increased sympathomimetic effects, such as increased blood pressure, chest pain and headache.
