A long-acting antimuscarinic (LAMA) inhaler
Glycopyrronium
A once-daily maintenance inhaler that keeps the airways open in COPD.
What is Glycopyrronium?
Glycopyrronium is a long-acting antimuscarinic (LAMA) maintenance inhaler used in COPD. It is taken regularly, usually once a day, to keep the airways relaxed and open and ease breathlessness. It is a preventer-type inhaler, not a reliever, so it does not work quickly enough for sudden symptoms.
Education and reference only. This is a plain-language guide to Glycopyrronium — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Glycopyrronium, sold as Seebri, is a long-acting antimuscarinic (LAMA) inhaler used in chronic obstructive pulmonary disease (COPD). It is a maintenance inhaler taken on a regular schedule.
How it works
It blocks muscarinic receptors in the airways, where the chemical messenger acetylcholine would normally tighten the surrounding muscle. By blocking this signal the airway muscle relaxes and stays open for many hours, making breathing easier over the day.

Weighing it up
Advantages & disadvantages of Glycopyrronium
Advantages

Practical use
Good to know
It is a regular, daily maintenance inhaler that works steadily in the background, so it must not be relied on for sudden breathlessness, which still needs a separate reliever (rescue) inhaler. A common effect is a dry mouth. Getting the inhaler technique right matters, so ask your nurse or pharmacist to check it.
Who should not take it / use with caution
- People who have had an allergic reaction to glycopyrronium.
- It should be used with caution in narrow-angle glaucoma.
- It should be used with caution in those with urinary retention or an enlarged prostate.
- It is licensed for COPD, not for asthma.
Monitoring
- Symptoms and breathlessness are reviewed at regular checks.
- Inhaler technique is checked.
- Be alert for eye pain or trouble passing urine.
Side effects
- Dry mouth.
- Throat irritation or cough.
- Headache and urine or sinus infections.
- Rarely, blurred vision, eye pain (possible glaucoma) or difficulty passing urine, which should be reported.
Key interactions
- Using it with other antimuscarinic medicines can add to effects like dry mouth and urinary problems.

- Tell your team about all your inhalers and medicines so they can be reviewed.

Answers
Glycopyrronium: frequently asked questions
Is this a reliever inhaler?
No. Glycopyrronium is a maintenance (preventer-type) inhaler taken regularly to keep the airways open. For sudden breathlessness you still need your separate reliever inhaler.
How often do I use it?
It is usually used once a day, at about the same time each day, even when you feel well.
Why do I get a dry mouth?
Dry mouth is a common effect of this type of inhaler. Sipping water or sugar-free sweets can help; tell your team if it is troublesome.
Can I use it if I have glaucoma?
It should be used with caution if you have narrow-angle glaucoma. Report any eye pain, redness or blurred vision promptly.
Why does inhaler technique matter so much?
If the inhaler is not used correctly, the medicine may not reach your airways, so it will not work as well. Ask your nurse or pharmacist to check your technique.
