What AERON is used for
This medicine is used to treat
chronic obstructive bronchitis
people who have difficulty breathing during or after surgery using assisted ventilation
Asthma is a disease where the lining of the lungs becomes inflamed (red and swollen),
making it difficult to breathe. This may be due to an allergy to house dust mites,
smoke or other irritants.
Chronic obstructive bronchitis is a lung condition that can cause difficulty in breathing,
wheeziness and constant coughing.
AERON contains the active ingredient ipratropium bromide monohydrate. It belongs to
a group of medicines called anticholinergic bronchodilators.
AERON opens up the air passages in people suffering from asthma, chronic bronchitis
and difficulty breathing during or after surgery.
It begins to act quickly after use but may take up to 2 hours to give maximum benefit.
