Enurev Breezhaler is indicated as a maintenance bronchodilator treatment to relieve symptoms in adult patients with chronic obstructive pulmonary disease (COPD).
What is Enurev Breezhaler?
Enurev Breezhaler is a medicine that contains the active substance glycopyrronium bromide. It is available as capsules containing a powder for inhalation.
What is Enurev Breezhaler used for?
Enurev Breezhaler is used to relieve the symptoms of chronic obstructive pulmonary disease (COPD) in adults. COPD is a long-term disease in which the airways and air sacs inside the lungs become damaged or blocked, leading to difficulty breathing. Enurev Breezhaler is used for maintenance (regular) treatment.
The medicine can only be obtained with a prescription.
How is Enurev Breezhaler used?
Enurev Breezhaler capsules are only used with the Enurev Breezhaler inhaler and must not be swallowed. To take a dose, the patient places a capsule into the inhaler and breathes the powder contained in the capsule in through the mouth. For detailed information on how to use the inhaler correctly, see the instructions in the package leaflet.
The recommended dose is one capsule once a day at the same time each day. Patients should not take more than one capsule in a day.
How does Enurev Breezhaler work?
Enurev Breezhaler is an anticholinergic bronchodilator. This means that it widens the airways by blocking some receptors in muscle cells in the lungs called muscarinic receptors, which control the contraction of muscles. When the active substance in Enurev Breezhaler, glycopyrronium bromide, is inhaled, it causes the muscles of the airways to relax, helping to keep the airways open and allowing the patient to breathe more easily.
How has Enurev Breezhaler been studied?
The effects of Enurev Breezhaler were first tested in experimental models before being studied in humans.
Enurev Breezhaler has been studied in two main studies involving a total of 1,888 patients with COPD, where Enurev Breezhaler was compared with placebo (a dummy treatment). In both studies, the main measure of effectiveness was how Enurev Breezhaler improved patients’ forced expiratory volumes (FEV1, the maximum volume of air a person can breathe out in one second) after 12 weeks of treatment.
What benefit has Enurev Breezhaler shown during the studies?
Enurev Breezhaler was more effective than placebo at improving how well the lungs work in patients with COPD: after 12 weeks of treatment, the increase in FEV1 with Enurev Breezhaler was 97 ml more than with placebo in the first study and 108 ml more in the second study.
What is the risk associated with Enurev Breezhaler?
The most common side effects with Enurev Breezhaler (seen in between 1 and 10 patients in 100) are dry mouth, nasopharyngitis (inflammation of the nose and throat), insomnia (difficulty sleeping) and gastroenteritis (diarrhoea and vomiting). For the full list of all side effects reported with Enurev Breezhaler, see the package leaflet.
Enurev Breezhaler must not be used in people who are hypersensitive (allergic) to glycopyrronium bromide or any of the other ingredients.
Why has Enurev Breezhaler been approved?
The CHMP noted that Enurev Breezhaler had a modest but relevant benefit for patients in terms of improving lung function, and was also seen to improve the symptoms of COPD. The CHMP also noted that the fact that the medicine is used once a day may help patients to comply with their treatment. In addition, there were no major safety concerns with Enurev Breezhaler, with side effects being similar to other anticholinergic bronchodilator medicines. Therefore, the CHMP decided that Enurev Breezhaler’s benefits are greater than its risks and recommended that it be given marketing authorisation.
What measures are being taken to ensure the safe use of Enurev Breezhaler?
As anticholinergic bronchodilator medicines may have an effect on the heart and blood vessels, the company will continue to closely monitor the medicine’s cardiovascular effects and will carry out a further study in patients to identify any potential risks.
