4.2 Posology and method of administration

The dosage should be adapted to the individual needs of the patient. The following doses are recommended:

Adults (including the elderly) and adolescents > 12 years of age:

500 micrograms 3 to 4 times daily.

For treatment of acute bronchospasm, 500 micrograms.

Repeated doses can be administered until the patient is stable. The time interval between the doses may be determined by the physician.

It is advisable not to exceed the recommended daily dose during either acute or maintenance treatment. Daily doses exceeding 2 mg in adults and adolescents > 12 years of age should only be given under medical supervision.

Children < 12 years of age:

250 micrograms up to a total daily dose of 1mg.

The time interval between doses may be determined by the physician.

For acute bronchospasm, repeated doses may be administered until the patient is stable. The time interval between doses may be determined by the physician.

It is advisable not to exceed the recommended daily dose. Daily doses exceeding 1mg in this age group should be given under medical supervision.

There is limited information for children < 6 years of age, therefore the recommended dose should only be given under medical supervision.

ATROVENT UDVs can be administered combined with an inhaled beta2-agonist.

The dose of nebuliser solution may need to be diluted in order to obtain a final volume suitable for the particular nebuliser being used; if dilution is necessary use only sterile sodium chloride 0.9% solution.

If therapy does not produce a significant improvement or if the patient's condition gets worse, medical advice must be sought. The patient should be instructed that in the case of acute or rapidly worsening dyspnoea a physician should be consulted immediately.

ATROVENT UDVs can be administered using a range of commercially available nebulising devices.

ATROVENT UDVs and disodium cromoglycate inhalation solutions that contain the preservative benzalkonium chloride should not be administered simultaneously in the same nebuliser as precipitation may occur.

The unit dose vials are intended only for inhalation with suitable nebulising devices and should not be taken orally or administered parenterally.

Please refer to the patient information leaflet for instructions on use with a nebuliser.

4.3 Contraindications

ATROVENT UDVs are contraindicated in patients with known hypersensitivity to atropine or its derivatives (such as the active substance ipratropium bromide) or to any other component of the product.

Go to top of the page
4.4 Special warnings and precautions for use


Immediate hypersensitivity reactions following the use of ATROVENT have been demonstrated by rare cases of urticaria, angioedema, rash, bronchospasm, oropharyngeal oedema and anaphylaxis.

Paradoxical bronchospasm

As with other inhaled medicines ATROVENT may result in paradoxical bronchospasm that may be life-threatening. If paradoxical bronchospasm occurs ATROVENT should be discontinued immediately and substituted with an alternative therapy.

Ocular complications

Caution is advocated in the use of anticholinergic agents in patients predisposed to narrow-angle glaucoma.

There have been isolated reports of ocular complications (i.e. mydriasis, increased intra-ocular pressure, narrow-angle glaucoma, eye pain) when aerosolised ipratropium bromide, either alone or in combination with an adrenergic beta2-agonist, has come into contact with the eyes.

Eye pain or discomfort, blurred vision, visual halos or coloured images in association with red eyes from conjunctival congestion and corneal oedema may be signs of acute narrow-angle glaucoma. Should any combination of these symptoms develop, treatment with miotic drops should be initiated and specialist advice sought immediately.

Patients must be instructed in the correct administration of ATROVENT UDVs. Care must be taken not to allow the solution or mist to enter the eyes. It is recommended that the nebulised solution is administered via a mouthpiece. If this is not available and a nebuliser mask is used, it must fit properly. Patients who may be predisposed to glaucoma should be warned specifically to protect their eyes.

Renal and urinary effects

ATROVENT should be used with caution in patients with pre-existing urinary outflow tract obstruction (e.g. prostatic hyperplasia or bladder-outflow obstruction).

Gastro-intestinal motility disturbances

As patients with cystic fibrosis may be prone to gastro-intestinal motility disturbances, ATROVENT, as with other anticholinergics, should be used with caution in these patients.

4.5 Interaction with other medicinal products and other forms of interaction

The chronic co-administration of ATROVENT inhalation with other anticholinergic drugs has not been studied. Therefore, the chronic co-administration of ATROVENT with other anticholinergic drugs is not recommended.

There is evidence that the administration of ATROVENT with beta-adrenergic drugs and xanthine preparations may intensify the bronchodilator effect of ATROVENT.

The risk of acute glaucoma in patients with a history of narrow-angle glaucoma (see section Special warnings and precautions for use) may be increased when nebulised ipratropium bromide and beta2-agonists are administered simultaneously.

4.6 Fertility, pregnancy and lactation


The safety of ATROVENT during human pregnancy has not been established. The benefits of using ATROVENT during a confirmed or suspected pregnancy must be weighed against the possible hazards to the unborn child. Nonclinical studies have shown no embryotoxic or teratogenic effects following inhalation or intranasal application at doses considerably higher than those recommended in man.


It is not known whether ipratropium bromide is excreted into breast milk. It is unlikely that ipratropium bromide would reach the infant to an important extent, however caution should be exercised when ATROVENT is administered to nursing mothers.


Clinical data on fertility are not available for ipratropium bromide.

Nonclinical studies performed with ipratropium bromide showed no adverse effect on fertility.

4.7 Effects on ability to drive and use machines

No studies on the effects on the ability to drive and use machines have been performed. However, patients should be advised that they may experience undesirable effects such as dizziness, accommodation disorder, mydriasis and blurred vision during treatment with ATROVENT. Therefore, caution should be recommended when driving a car or operating machinery.

Go to top of the page
4.8 Undesirable effects

Many of the listed undesirable effects can be assigned to the anticholinergic properties of ATROVENT. As with all inhalation therapy ATROVENT may show symptoms of local irritation. Adverse drug reactions were identified from data obtained in clinical trials and pharmacovigilance during post approval use of the drug.

The most frequent side effects reported in clinical trials were headache, throat irritation, cough, dry mouth, gastro-intestinal motility disorders (including constipation, diarrhoea and vomiting), nausea, and dizziness.

4.9 Overdose

No symptoms specific to overdosage have been encountered. In view of the wide therapeutic window and topical administration of ATROVENT, no serious anticholinergic symptoms are to be expected. As with other anticholinergics, dry mouth, visual accommodation disorder and tachycardia would be the expected symptoms and signs of overdose.

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Anticholinergics

ATC Code: R03BB01

ATROVENT is a quaternary ammonium compound with anticholinergic (parasympatholytic) properties. In nonclinical studies, it appears to inhibit vagally mediated reflexes by antagonising the action of acetylcholine, the transmitter agent released from the vagus nerve. Anticholinergics prevent the increase in intracellular concentration of Ca++ which is caused by interaction of acetylcholine with the muscarinic receptor on bronchial smooth muscle. Ca++ release is mediated by the second messenger system consisting of IP3 (inositol triphosphate) and DAG (diacylglycerol).

The bronchodilation following inhalation of ATROVENT is primarily local and site specific to the lung and not systemic in nature.

Preclinical and clinical evidence suggest no deleterious effect of ATROVENT on airway mucous secretion, mucociliary clearance or gas exchange.

In controlled 90 day studies in patients with bronchospasm associated with chronic obstructive pulmonary disease (e.g. chronic bronchitis and emphysema) significant improvements in pulmonary function (FEV1 and FEF 25-75% increases of 15% or more) occurred within 15 minutes, reached a peak in 1-2 hours, and persisted in the majority of patients up to 6 hours.

The bronchodilator effect of ATROVENT in the treatment of acute bronchospasm associated with asthma has been shown in studies in adults and children ≥ 6 years of age. In most of these studies ATROVENT was administered in combination with an inhaled beta2-agonist.

Although the data are limited, ATROVENT has been shown to have a therapeutic effect in the treatment of bronchospasm associated with viral bronchiolitis and bronchopulmonary dysplasia in infants and very small children.

5.2 Pharmacokinetic properties


The therapeutic effect of ATROVENT is produced by a local action in the airways. Time courses of bronchodilation and systemic pharmacokinetics do not run in parallel.

Following inhalation, 10 to 30% of a dose is generally deposited in the lungs, depending on the formulation, device and inhalation technique. The major part of the dose is swallowed and passes through the gastro-intestinal tract.

The portion of the dose deposited in the lungs reaches the circulation rapidly (within minutes).

Cumulative renal excretion (0-24 hrs) of the parent compound is approximated to 46% of an intravenously administered dose, below 1% of an oral dose and approximately 3 to 13% of an inhaled dose. Based on these data the total systemic bioavailability of oral and inhaled doses of ipratropium bromide is estimated at 2% and 7 to 28% respectively.

Taking this into account, swallowed dose portions of ipratropium bromide do not relevantly contribute to systemic exposure.


Kinetic parameters describing the distribution of ipratropium bromide were calculated from plasma concentrations after i.v. administration.

A rapid biphasic decline in plasma concentrations is observed. The apparent volume of distribution at steady-state (Vdss) is approximately 176 L (≈ 2.4 L/kg). The drug is minimally (less than 20%) bound to plasma proteins. Nonclinical data indicate that the quaternary amine ipratropium does not cross the placental or the blood-brain barrier.


After intravenous administration approximately 60% of a dose is metabolised probably the major portion in the liver by oxidation.

The known metabolites, which are formed by hydrolysis, dehydration or elimination of the hydroxy-methyl group in the tropic acid moiety, show very little or no affinity for the muscarinic receptor and have to be regarded as ineffective.


The half-life of the terminal elimination phase is approximately 1.6 hours.

Ipratropium has a mean total clearance of 2.3 L/min and a renal clearance of 0.9 L/min.

In an excretion balance study cumulative renal excretion (6 days) of drug-related radioactivity (including parent compound and all metabolites) accounted for 72.1% after intravenous administration, 9.3% after oral administration and 3.2% after inhalation. Total radioactivity excreted via the faeces was 6.3% following intravenous application, 88.5% following oral dosing and 69.4% after inhalation. Regarding the excretion of drug-related radioactivity after intravenous administration, the main excretion occurs via the kidneys. The half-life for elimination of drug-related radioactivity (parent compound and metabolites) is 3.6 hours.
