Clear and colourless solution
pH: 3.2 to 3.8
Osmolality: 270-330 mOsm/kg
- Instruction Clinical Particulars
- 4.1 Therapeutic indications
For the treatment of acute hypotension due to loss of vasoconstrictor tone as may occur during spinal anaesthesia and as an adjunct to accepted remedial procedures.4.2 Posology and method of administration
\*\*Posology\*\*
\*Adults\*
Direct intravenous injection in grave emergencies: 0.5 to 5 mg (1 to 10 ml).
The maximum cumulative dose after repeated direct intravenous injections is 5mg. One direct IV injection should usually not exceed 1mg.
Direct intravenous injection may be followed by an infusion of 15 - 100 mg in 500 mL of infusion liquid, using an appropriate metaraminol formulation and administration.
Metaraminol 0.5 mg/ml solution for injection in pre-filled syringe is not suitable for intravenous infusion.
\*Paediatric population\*
Metaraminol should not be used in children under 12 years of age.
\*Elderly\*
The dosage may not require modification for elderly patients; however, geriatric patients may be more sensitive to sympathomimetic agents, therefore particular caution should be taken in this age group.
\*\*Method of administration\*\*
For intravenous use.
\*\*Metaraminol 0.5 mg/ml, solution for injection should not be diluted before use: it is supplied ready to use in pre-filled syringes.\*\*
The pre-filled syringe is not suitable for syringe pump drivers.4.3 Contraindications
Metaraminol, solution for injection in pre-filled syringe should not be used concurrently with cyclopropane or halothane anaesthesia, unless clinical circumstances demand it.
Metaraminol, solution for injection in pre-filled syringe is contra-indicated in patients who are hypersensitive to the active ingredient or any of the excipients listed in section 6.1.
There is insufficient data to recommend use in children under 12 years of age4.4 Special warnings and precautions for use
Caution should be exercised to avoid excessive blood-pressure changes since response to treatment with metaraminol is very variable and the ensuing control of the blood pressure may prove difficult.
Rapidly induced hypertensive responses have been reported to cause acute pulmonary oedema, cardiac arrhythmias and arrest. Metaraminol should be used with caution in patients with cirrhosis; electrolyte levels should be adequately restored if a diuresis ensues. A fatal ventricular arrhythmia was reported in a patient with Laennec's cirrhosis while receiving metaraminol tartrate. In several instances ventricular extrasystoles that appeared during infusion of metaraminol promptly subsided when the rate of flow was reduced.
With the prolonged action of Metaraminol, a cumulative effect is possible. An excessive vasopressor response may cause a prolonged elevation of blood pressure, even after discontinuation of therapy. Metaraminol should be used with caution in cases of heart disease, hypertension, thyroid disease or diabetes mellitus because of the vasoconstrictor action.
Sympathomimetic amines may provoke a relapse in patients with a history of malaria.
When vasopressor amines are used for long periods, the resulting vasoconstriction may prevent adequate expansion of circulating volume and may cause perpetuation of the shock state. There is evidence that plasma volume may be reduced in all types of shock, and that the measurement of central venous pressure is useful in assessing the adequacy of the circulating blood volume. Blood, or plasma-volume expanders, should therefore be employed when the principal reason for hypotension of shock is decreased circulating volume.
In choosing the site for injection, it is important to avoid those areas generally recognised as being unsuitable for the use of any pressor agent. Although the urgent nature of the patient's condition may force the choice of an unsuitable injection site, the preferred areas of injection should be used when possible. The larger veins of the antecubital fossa or thigh are preferred to the veins in the ankle or dorsum of the hand, particularly in patients with peripheral vascular disease, diabetes mellitus, Buerger's disease or conditions with coexistent hypercoagulability.
In case of extravasation, local administration of an alpha blocker such as Phentolamine may prevent the risk of necrosis.
Metaraminol, solution for injection in pre-filled syringe is to be used by direct intravenous injection only. Bolus doses should be administered at the minimal efficient dose. Metaraminol should be administered under comprehensive hemodynamic monitoring.
This medicinal product contains 35 mg sodium per 10 ml syringe, equivalent to 1.8 % of the WHO recommended maximum daily intake of 2 g sodium for an adult.4.5 Interaction with other medicinal products and other forms of interaction
Metaraminol, solution for injection in pre-filled syringe should not be used concurrently with cyclopropane or halothane anaesthesia, unless clinical circumstances demand it, due to a risk of serious venticular arrhythmia.
Metaraminol should be used with caution in patients receiving digitalis, since the combination of digitalis and sympathomimetic amines is capable of causing ectopic arrhythmic activity.
Monoamine oxidase inhibitors have been reported to potentiate the action of sympathomimetic amines. The pressor effect of metaraminol is decreased but not reversed by alpha-adrenergic blocking agents.
A close monitoring of blood pressure is recommended in case of co-administration with oxytocic drugs due to the risk of enhancement of metaraminol effects.
In case of co-administration of metaraminol and ergot alkaloids, there is a risk of vasoconstriction and/or hypertensive crisis.
Co-administration with tricyclic antidepressants may enhance the effect of metaraminol.
Co-administration with doxapram may enhance the effect of metaraminol.
Co-administration with Guanethidine may alter the effects of both medications.4.6 Fertility, pregnancy and lactation
\*Pregnancy\*
There are no well-controlled studies in pregnant women. Metaraminol should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus.
\*Breastfeeding\*
It is not known whether metaraminol is secreted in human milk. Because many drugs are secreted in human milk, caution should be exercised if metaraminol is given to a breastfeeding mother.
\*Fertility\*
There are no fertility data available.4.7 Effects on ability to drive and use machines
Not relevant.4.8 Undesirable effects
The frequency of adverse events with metaraminol has not been firmly established.
Excessive therapeutic effect leading to hypertension, quickly reversible by reducing the rate of infusion, and headaches are very common.
Adverse reactions listed below are classified according to frequency and system organ class (SOC). The frequencies of adverse reactions are ranked according to the following convention: Very Common (≥ 1/10); Common (≥ 1/100 to <1/10); Uncommon (≥ 1/1,000 to <1/100); Rare (≥ 1/10,000 to <1/1,000); Very rare (<1/10,000); Not known (cannot be estimated from the available data).

\*\*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 Yellow Card Scheme
Website: www.mhra.gov.uk/yellowcard4.9 Overdose
Metaraminol acts rapidly. The major therapeutic effects are complete within an hour of parenteral administration. Overdosage may result in severe hypertension accompanied by headache, constricting sensation in the chest, nausea, vomiting, euphoria, diaphoresis, pulmonary oedema, tachycardia, bradycardia, sinus arrhythmia, atrial or ventricular arrhythmias, myocardial infarction, cardiac arrest, convulsions or cerebral haemorrhage.
If the drug has been ingested, induce emesis or perform gastric lavage. If metaraminol has been administered by subcutaneous or intramuscular injection, local ice packs may be applied to delay absorption.
If needed, alpha-adrenergic blocking agents may also be useful for reducing hypertension and may have a beneficial effect on cardiac arrhythmia, if present.
Parenteral diazepam may be given for convulsions.
- Instruction Pharmacology
- 5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Adrenergic and dopaminergic agent. ATC code: C01CA09.
Metaraminol is a sympathomimetic agent with direct and indirect effects on adrenergic receptors. It has both alpha and beta-adrenergic activity, the former being predominant.
Metaraminol increases the force of myocardial contractions as well as having a peripheral vasoconstrictor action. It increases both systolic and diastolic blood pressures.
The vasoconstrictor action of metaraminol is not affected by depletion of the tissue stores of noradrenaline.
Metaraminol is highly effective in displacing and replacing noradrenaline from the stores in adrenergic neurones and competitively inhibits noradrenaline uptake. The metaraminol that is taken up by the adrenergic neurones then acts as a false transmitter.
The overall effects of metaraminol are similar to those of noradrenaline but it is much less potent and has a more prolonged action. It can cause pulmonary vasoconstriction, and pulmonary blood pressure is elevated when cardiac output is reduced.5.2 Pharmacokinetic properties
The pressor effect of a single dose of metaraminol lasts from about 20 minutes up to one hour. Its onset is around one or two minutes after direct intravenous injection.
The vasopressor effects taper off when therapy is stopped.5.3 Preclinical safety data
No relevant information.
