Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Hospira Glycopyrrolate Injection.

What is in this leaflet

This leaflet answers some common questions about Hospira™ Glycopyrrolate Injection. It does not contain all of the available information.

It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Hospira™ Glycopyrrolate Injection against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What Hospira™ Glycopyrrolate Injection is used for

Hospira™ Glycopyrrolate Injection may be used;

  • before surgery to reduce the amount of saliva produced by your mouth, and other secretions produced in your lungs and stomach
  • before or during surgery to maintain your heart’s normal beating rhythm, or
  • it may also used to counter the effects of some other medicines, which can slow your heartbeat or produce excessive secretions when used during surgery.

This medicine belongs to a group of medicines called “anticholinergics” which work in the nervous system to block an enzyme which is responsible for producing saliva in your mouth, and secretions in your stomach and lungs. This enzyme also slows down the heart rate. When this enzyme is blocked, secretions dry up and the heart rate increases.

Your doctor may have prescribed Hospira™ Glycopyrrolate Injection for another purpose.

Ask your doctor if you have any questions about why Hospira™ Glycopyrrolate Injection has been prescribed for you.

Hospira™ Glycopyrrolate Injection is not addictive.

This medicine is available only with a doctor’s prescription.

Your doctor or pharmacist has more information on medicines to be careful with, or avoid, when given Hospira™ Glycopyrrolate Injection.

How Hospira™ Glycopyrrolate Injection is given

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box/bottle, ask your doctor or pharmacist for help.

How much is given

The dose of Hospira™ Glycopyrrolate Injection may be different for each person. The dose given will depend on your condition, age and body weight. The usual adult dose is 200 to 400 micrograms. Your doctor will decide the right dose for you. For children aged 1 month to 12 years, the usual dose depends on their bodyweight.

How it is given

Hospira™ Glycopyrrolate Injection will be given to you by injection into either a vein or a muscle before the anaesthetic.

How long is it given for

Hospira™ Glycopyrrolate Injection is usually given as a single dose. However, sometimes your doctor may decide you need more. Your doctor will decide how much Hospira™ Glycopyrrolate Injection you need.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre 13 11 26 for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have been given too much Hospira™ Glycopyrrolate Injection. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are having Hospira™ Glycopyrrolate Injection

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you have been given Hospira™ Glycopyrrolate Injection.

Tell any other doctors, dentists, and pharmacists who treat you that you have been given this medicine.

Always discuss with your doctor any problems or difficulties during or after having Hospira™ Glycopyrrolate Injection.

Things you must not do

Do not drive or operate machinery, or perform hazardous work until you know how Hospira™ Glycopyrrolate Injection affects you. Hospira™ Glycopyrrolate Injection may cause drowsiness or blurred vision in some people and therefore may affect alertness.

Things to be careful of

Be careful if you are elderly, unwell or taking other medicines. You may experience side effects such as drowsiness or blurred vision, which may increase the risk of a fall.

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.

Be careful during warm weather and higher temperature, and/or with physical exercise after use of Hospira™ Glycopyrrolate Injection. It may reduce your ability to sweat and can therefore cause overheating.

4 Clinical Particulars

4.1 Therapeutic Indications

1. As a preoperative antimuscarinic to reduce salivary, tracheobronchial and pharyngeal secretions, and to reduce the acidity and volume of the gastric contents.
2. As a preoperative or intra-operative antimuscarinic to attenuate or prevent intra­operative bradycardia associated with the use of suxamethonium or due to cardiac vagal reflexes.
3. To protect against the peripheral muscarinic actions (e.g. bradycardia and excessive secretions) of anticholinesterases such as neostigmine or pyridostigmine given to reverse neuromuscular blockade produced by non-depolarising muscle relaxants.

4.2 Dose and Method of Administration

Dosage.

Pre-anaesthetic use.

Adults.

200 microgram to 400 microgram intravenously or intramuscularly before the induction of anaesthesia.
Alternatively, a dose of 4 to 5 microgram/kg up to a maximum of 400 micrograms may be used. Larger doses may result in profound and prolonged antisialogogue effect, which may be unpleasant for the patient.

Children.

See Section 4.3 Contraindications. 1 month to 12 years of age 4 to 8 microgram/kg up to a maximum of 200 microgram intravenously or intramuscularly before the induction of anaesthesia. Larger doses may result in profound and prolonged antisialogogue effect which may be unpleasant for the patient.
Intraoperative use. When used to treat arrhythmias associated with traction reflexes, the usual attempts should be made to determine the aetiology of the arrhythmia, and the surgical or anaesthetic manipulations necessary to correct parasympathetic imbalance should be performed.

Adults.

In those situations where intraoperative use is indicated, a single dose of 200 to 400 microgram (or 4 to 5 microgram/kg up to a maximum of 400 microgram) by intravenous injection should be used. This dose may be repeated if necessary.

Children.

(1 month to 12 years of age). In those situations where intraoperative use is indicated, a single dose of 4 to 8 microgram/kg or up to a maximum of 200 microgram by intravenous injection should be used. This dose may be repeated if necessary.
Reversal of neuromuscular blockade.

Adults.

200 microgram intravenously per 1 mg neostigmine or the equivalent dose of pyridostigmine. Alternatively, a dose of 10-15 microgram/kg intravenously with 0.05 mg/kg neostigmine or equivalent dose of pyridostigmine. Hospira Glycopyrrolate Injection may be administered simultaneously from the same syringe with the anticholinesterase; greater cardiovascular stability results from this method of administration.

Children (1 month to 12 years of age).

10 microgram/kg intravenously with 0.05 mg/kg neostigmine or the equivalent dose of pyridostigmine. Hospira Glycopyrrolate Injection may be administered simultaneously from the same syringe with the anticholinesterase; greater cardiovascular stability results from this method of administration.

Method of administration.

For intramuscular or intravenous administration.
Product is for single use in one patient only. Discard any residue.

4.3 Contraindications

Known hypersensitivity to glycopyrronium bromide (glycopyrrolate), or any of the inactive ingredients (see Section 4.8 Adverse Effects (Undesirable Effects)).

4.4 Special Warnings and Precautions for Use

Glycopyrronium bromide (glycopyrrolate) should be used with caution, if at all, in patients with glaucoma or asthma.
Glycopyrronium bromide (glycopyrrolate) should be used with caution in patients with any of the following conditions: obstructive uropathy, obstructive disease of the gastrointestinal tract, paralytic ileus, intestinal atony, unstable cardiovascular status in acute haemorrhage, severe ulcerative colitis and toxic megacolon complicating ulcerative colitis, autonomic neuropathy and prostatic hypertrophy.
Diarrhoea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. In this instance treatment with this drug would be inappropriate and possibly harmful.
In the case of ulcerative colitis, large doses of glycopyrronium bromide (glycopyrrolate) may suppress intestinal motility resulting in production of paralytic ileus perhaps precipitating or aggravating toxic megacolon.
Hiatus hernia associated with reflux oesophagitis may be aggravated following administration of this medicine.
Use with caution in patients with coronary artery disease; congestive heart failure; cardiac arrhythmias; hypertension or hyperthyroidism since an increase in heart rate may occur. Investigate any tachycardia before giving glycopyrronium bromide (glycopyrrolate) as an increase in heart rate may occur.
In the presence of fever, as in high environmental temperature, and physical exercise, reduced sweating can occur with glycopyrronium bromide (glycopyrrolate) causing heat prostration (fever and heat stroke). Use very cautiously when the ambient temperature is high and in pyrexic patients, especially children and the elderly, who have a tendency to sweat less.
Large doses of quaternary ammonium anticholinergic compounds have been shown to block end plate nicotinic receptors. This should be considered before using glycopyrronium bromide (glycopyrrolate) in patients with myasthenia gravis.

Use in renal impairment.

The duration of effect of glycopyrronium bromide (glycopyrrolate) may be prolonged in patients with renal impairment since glycopyrronium bromide (glycopyrrolate) is excreted mostly in urine as unchanged drug. Dosage adjustment may be needed for patients in renal failure.

Use in the elderly.

Clinical studies of glycopyrronium bromide (glycopyrrolate) did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy.

Paediatric use.

Arrhythmias associated with the use of glycopyrronium bromide (glycopyrrolate) intravenously as a premedication or during anaesthesia appear to be more likely in paediatric patients than in adults.
Infants, patients with Down's Syndrome, and paediatric patients with spastic paralysis or brain damage may experience an increased response to anticholinergics, thus increasing the potential for side effects.
A paradoxical reaction characterised by hyperexcitability may occur in paediatric patients taking large doses of anticholinergics including glycopyrronium bromide (glycopyrrolate). Infants and young children are especially susceptible to the toxic effects of anticholinergics.
Safety and effectiveness of long-term IV use has not been established in paediatric patients. Long-term use of glycopyrronium bromide (glycopyrrolate) is therefore not recommended in paediatric patients.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

The use of glycopyrronium bromide (glycopyrrolate), like atropine, with or within several hours of ritodrine hydrochloride administration may result in a drug interaction causing tachycardia.
The intravenous administration of any anticholinergic in the presence of cyclopropane anaesthesia can result in ventricular arrhythmias; therefore, caution should be observed if glycopyrronium bromide (glycopyrrolate) is used during cyclopropane anaesthesia. If the drug is given in small incremental doses of 100 microgram or less, the likelihood of producing ventricular arrhythmias is reduced.
Anticholinergic agents may delay absorption of other medications given concomitantly.
Excessive cholinergic blockade can occur if glycopyrronium bromide (glycopyrrolate) is given concomitantly with belladonna alkaloids or other synthetic anticholinergic agents (such as antiparkinsonism agents), phenothiazines, tricyclic antidepressants, disopyramide, procainamide, quinidine, some antihistamines, narcotic analgesics such as pethidine, thioxanthenes, butyrophenones or amantadine.
Concurrent administration of anticholinergics and corticosteroids may result in increased intraocular pressure.
Concurrent use of anticholinergic agents with slow dissolving tablets of digoxin may cause increased serum digoxin levels.
Glycopyrronium bromide (glycopyrrolate) is compatible for mixing and injection with pethidine hydrochloride; morphine sulfate; droperidol plus fentanyl citrate; hydroxyzine; neostigmine; promethazine and pyridostigmine. Glycopyrronium bromide (glycopyrrolate) may be mixed with 4% to 10% glucose in water or saline, or it may be administered via the tubing of a running infusion of physiological saline, glucose, or lactated ringers solution.
Since the stability of glycopyrronium bromide (glycopyrrolate) is questionable above a pH of 6.0, do not inject glycopyrronium bromide (glycopyrrolate) at the same intramuscular site or combine it in the same syringe with: thiopentone sodium; chloramphenicol; diazepam; dimenhydrinate; methohexitone sodium; pentazocine lactate; pentobarbitone sodium; quinalbarbitone; or sodium bicarbonate. A gas will evolve or a precipitate may form.
Mixing with dexamethasone, sodium phosphate or a buffered solution of lactated ringers solution will result in a pH higher than 6.0.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

In animal reproduction studies diminished rates of conception and of survival of weaning were observed in rats, in a dose related manner. Studies in dogs suggest that this may be due to diminished seminal secretion, which is evident at high doses of glycopyrronium bromide (glycopyrrolate). The significance of this for humans is not clear.
(Category B2)1
Clinically, the safe use of glycopyrronium bromide (glycopyrrolate) has not been established in pregnancy. Single dose studies in humans found that only very small amounts of glycopyrronium bromide (glycopyrrolate) passed the placental barrier. Therefore, the drug should not be used in pregnant women or those likely to become pregnant, unless the expected benefits outweigh any potential risk.
Reproduction studies in rats and rabbits did not reveal any teratogenic effects from glycopyrronium bromide (glycopyrrolate).
1 Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human foetus having been observed.
Studies in animals are inadequate or may be lacking, but available data show no evidence of an increased occurrence of foetal damage.
Anticholinergic agents may suppress lactation. It is not known whether glycopyrronium bromide (glycopyrrolate) is excreted in human milk.
Therefore, it is not recommended for nursing mothers unless the expected benefits outweigh any potential risk.

4.7 Effects on Ability to Drive and Use Machines

In the ambulatory patient glycopyrronium bromide (glycopyrrolate) may produce drowsiness or blurred vision. In this event, the patient should be warned not to engage in activities requiring mental alertness such as operating a motor vehicle or other machinery, or performing hazardous work while taking this drug.

4.8 Adverse Effects (Undesirable Effects)

The following reported adverse effects are extensions of glycopyrronium bromide (glycopyrrolate)'s fundamental pharmacological actions:

Cardiovascular.

Tachycardia, ventricular fibrillation, bradycardia, palpitation and arrhythmia, hypertension, hypotension, cardiac arrest, heart block, prolonged QTc interval.

Dermatological.

Flushing and inhibition of sweating. Severe allergic reactions or drug idiosyncrasies including urticaria and other dermal manifestations, pruritus, dry skin.

Gastrointestinal.

Nausea, vomiting, dry mouth, constipation, taste alterations, including loss of taste.

Genitourinary.

Urinary hesitancy and retention, impotence.

Ocular.

Blurred vision due to mydriasis, cycloplegia, photophobia, increased ocular tension.

Nervous system.

Inhibition of transmission at neuromuscular junction, headache, nervousness, drowsiness, dizziness, seizure, insomnia, some degree of mental confusion, especially in the elderly, hyperexcitability in children.

Pregnancy and perinatal.

Suppression of lactation.

Respiratory system.

Respiratory arrest.

General.

Hyperpyrexia, bloated feeling, anaphylaxis/ anaphylactoid reaction, and hypersensitivity. Injection site reactions including pruritus, oedema, erythema, pain have been reported rarely.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration 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 at www.tga.gov.au/reporting-problems.

4.9 Overdose

The signs and symptoms of overdosage reflect the pharmacological effects of glycopyrronium bromide (glycopyrrolate). These may include hypotension, respiratory failure and a curare like action, i.e. neuromuscular blockade leading to muscular weakness and possibly paralysis.
Treatment should be symptomatic. Dialysis is of no value because of low plasma concentrations of the drug.
To combat peripheral anticholinergic effects a quaternary ammonium anticholinesterase such as neostigmine methylsulfate may be given intravenously in increments of 0.25 mg in adults.
This dosage may be repeated every five to ten minutes until anticholinergic overactivity is reversed or up to a maximum of 2.5 mg. Proportionately smaller doses should be used in children. Indication for repetitive doses of neostigmine should be based on close monitoring of the decrease in heart rate and the return of bowel sounds.
In the unlikely event that CNS symptoms (excitement, restlessness, convulsions, psychotic behaviour) occur, physostigmine (which does cross the blood brain barrier) should be used. Physostigmine 0.5 to 2.0 mg should be slowly administered intravenously and repeated as necessary up to a total of 5 mg in adults. Proportionately smaller doses should be used in children.
Fever should be treated symptomatically. In the event of a curare like effect on respiratory muscles, artificial respiration should be instituted and maintained until effective respiratory action returns.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Glycopyrronium bromide (glycopyrrolate) is a synthetic anticholinergic agent. Like other anticholinergic (antimuscarinic) agents, it inhibits the action of acetylcholine on structures innervated by postganglionic cholinergic nerves and on smooth muscles that respond to acetylcholine but lack cholinergic innervation. These peripheral cholinergic receptors are present in the autonomic effector cells of smooth muscle, cardiac muscle, the sinoatrial node, the atrioventricular node, exocrine glands, and, to a limited degree, in the autonomic ganglia. Thus, it diminishes the volume and free acidity of gastric secretions and controls excessive pharyngeal, tracheal, and bronchial secretions. Doses which produce marked antisialogogue actions have little effect on heart rate, visual accommodation, or pupil size.
Glycopyrronium bromide (glycopyrrolate) antagonises muscarinic symptoms (e.g. bronchorrhoea, bronchospasm, bradycardia, and intestinal hypermotility) induced by cholinergic drugs such as anticholinesterases.
The highly polar quaternary ammonium group of glycopyrronium bromide (glycopyrrolate) limits its passage across lipid membranes, such as the blood brain barrier, in contrast to atropine sulfate and hyoscine hydrobromide, which are non-polar tertiary amines that penetrate lipid barriers easily.

Clinical trials.

No data available.

5.2 Pharmacokinetic Properties

Absorption.

Peak effects occur approximately 30 to 45 minutes after intramuscular administration. The vagal blocking effects persist for 2 to 3 hours and the antisialogogue effects persist up to 7 hours, periods longer than for atropine. With intravenous injection, the onset of action is generally evident within one minute.

Distribution and metabolism.

Pharmacokinetic studies in normal volunteers given a single intravenous infusion of 400 microgram glycopyrronium bromide (glycopyrrolate) showed that the drug undergoes a rapid distribution/ elimination phase (t1/2 = 5 min) followed by a more prolonged termination elimination phase (t1/2 = 1.7 hr). The peak plasma concentration immediately following the end of the infusion was 26.4 mg/mL (± 7.6), and the volume of distribution was 0.158 ± 0.28 L/kg, which suggests that glycopyrronium bromide (glycopyrrolate), is not widely distributed to the tissues.

Excretion.

Excretion is via the urine and bile. Radioactivity studies have shown that 85% is excreted in the urine within 48 hours, over 80% of this being unchanged drug.

5.3 Preclinical Safety Data

Genotoxicity.

Nonclinical studies in animals have not been performed to evaluate the genotoxic potential of glycopyrronium bromide (glycopyrrolate).

Carcinogenicity.

Long-term studies in animals have not been performed to evaluate the carcinogenic potential of glycopyrronium bromide (glycopyrrolate).
