Concentrate for solution for infusion
A clear colourless or yellowish solution
pH: 3.0 – 4.0
Osmolarity: approximately 280 mOsm/l
Indicated for use as an emergency measure in the restoration of blood pressure in
cases of acute hypotension.
Posology and method of administration
Initial rate of infusion:
When diluted as recommended in section 6.6 (the concentration of the
prepared infusion is 40 mg/litre noradrenaline base (80 mg/litre noradrenaline
tartrate)) the initial rate of infusion, at a body weight of 70 kg, should be
between 10 ml/hour and 20 ml/hour (0.16 to 0.33 ml/min). This is equivalent
to 0.4 mg/hour to 0.8 mg/hour noradrenaline base (0.8 mg/hour to 1.6 mg/hour
noradrenaline tartrate). Some clinicians may wish to start at a lower initial
infusion rate of 5 ml/hour (0.08 ml/min), equivalent to 0.2 mg/hour
noradrenaline base (0.4 mg/hour noradrenaline tartrate).
Titration of dose:
Once an infusion of noradrenaline has been established the dose should be
titrated in steps of 0.05 -0.1 µg/kg/min of noradrenaline base according to the
pressor effect observed. There is great individual variation in the dose
required to attain and maintain normotension. The aim should be to establish a
low normal systolic blood pressure (100 - 120 mm Hg) or to achieve an
adequate mean arterial blood pressure (greater than 65 - 80 mm Hg –
depending on the patient’s condition).
Noradrenaline Infusion Solution
40 mg/litre (40 µg /ml) noradrenaline base
Some clinicians may prefer to dilute to other concentrations. If dilutions other than 40
mg/l are used, check the infusion rate calculation carefully before starting treatment.
Renal or hepatic impairment:
There is no experience in treatment of renally or hepatically impaired patients
As for adults but see section 4.4.
Duration of Treatment and Monitoring:
Noradrenaline should be continued for as long as vasoactive drug support is indicated.
The patient should be monitored carefully for the duration of therapy. Blood pressure
should be carefully monitored for the duration of therapy.
Withdrawal of Therapy:
The noradrenaline infusion should be gradually decreased since abrupt withdrawal
can result in acute hypotension.
Route of Administration:
For intravenous use.
Method of administration:
Administer as a diluted solution via a central venous catheter.
The infusion should be at a controlled rate using either a syringe pump or an infusion
pump or a drip counter.

Hypersensitivity to noradrenaline tartrate or to any of the excipients listed in section
Special warnings and precautions for use
Noradrenaline should only be administered by healthcare professionals who are
familiar with its use.
Elderly patients may be especially sensitive to the effects of noradrenaline.
Particular caution should be observed in patients with coronary, mesenteric or
peripheral vascular thrombosis because noradrenaline may increase the ischemia and
extend the area of infarction. Similar caution should be observed in patients with
hypotension following myocardial infarction, in patients with Prinzmetal’s variant
angina and in patients with diabetes, hypertension or hyperthyroidism.
Noradrenaline should be used with caution in patients who exhibit profound hypoxia
Noradrenaline should be used only in conjunction with appropriate blood volume
replacement. When infusing noradrenaline, the blood pressure and rate of flow
should be checked frequently to avoid hypertension.
Extravasation of the solution may cause local tissue necrosis. The infusion site should
be checked frequently. If extravasation occurs, the infusion should be stopped and the
area should be infiltrated with phentolamine without delay.
Prolonged administration of any potent vasopressor may result in plasma volume
depletion which should be continuously corrected by appropriate fluid and electrolyte
replacement therapy. If plasma volumes are not corrected, hypotension may recur
when the infusion is discontinued, or blood pressure may be maintained at the risk of
severe peripheral and visceral vasoconstriction (e.g., decreased renal perfusion) with
diminution in blood flow and tissue perfusion with subsequent tissue hypoxia and
lactic acidosis and possible ischaemic injury.
Contains sodium. To be taken into consideration by patients on a controlled sodium
diet, see section 2.
Interaction with other medicinal products and other forms of interaction
The use of noradrenaline with volatile halogenated anaesthetic agents, monoamine
oxidase inhibitors, linezolid, tricyclic antidepressants, adrenergic-serotoninergic drugs
or any other cardiac sensitising agents is not recommended because severe, prolonged
hypertension and possible arrhythmias may result.
Fertility, pregnancy and lactation
Noradrenaline may impair placental perfusion and induce fetal bradycardia. It may
also exert a contractile effect on the pregnant uterus and lead to fetal asphyxia in late
pregnancy. These possible risks to the fetus should therefore be weighed against the
potential benefit to the mother.
No information is available on the use of noradrenaline in lactation.

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is
important. It allows continued monitoring of the benefit/risk balance of the medicinal
product. Healthcare professionals are asked to report any suspected adverse reactions
via the national reporting system listed in Appendix V
Overdosage may result in severe hypertension, reflex bradycardia, marked increase in
peripheral resistance and decreased cardiac output. 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.
Pharmacotherapeutic group: Adrenergic and dopaminergic agents, ATC code:
The vascular effects in the doses normally used clinically result from the
simultaneous stimulation of alpha and beta adrenergic receptors in the heart and
vascular system. Except in the heart, its action is predominantly on the alpha
receptors. This results in an increase in the force (and in the absence of vagal
inhibition, in the rate) of myocardial contraction. Peripheral resistance increases and
diastolic and systolic pressures are raised.
The increase in blood pressure may cause a reflex decrease in heart rate.
Vasoconstriction may result in decreased blood flow in kidneys, liver, skin and
smooth muscles. Local vasoconstriction may cause haemostasis and/or necrosis.
The effect on blood pressure disappears 1-2 minutes after stopping the infusion.
Up to 16% of an intravenous dose is excreted unchanged in the urine with methylated
and deaminated metabolites in free and conjugated forms.
Preclinical safety data
Most of the adverse effects attributable to sympathomimetics result from excessive
stimulation of the sympathetic nervous system via the different adrenergic receptors.
Noradrenaline may impair placental perfusion and induce fetal bradycardia. It may
also exert a contractile effect on the uterus and lead to fetal asphyxia in late
