Foster is a pressurised inhalation solution containing two active substances which are inhaled through the mouth and delivered directly into the lungs.
The two active substances are beclometasone dipropionate and formoterol fumarate dihydrate. Beclometasone dipropionate belongs to a group of medicines called corticosteroids which have an anti-inflammatory action reducing the swelling and irritation in the lungs.
Formoterol fumarate dihydrate belongs to a group of medicines called long-acting bronchodilators which relax the muscles in the airways and helps the patient to breathe more easily.
Together these two active substances make breathing easier, by providing relief from symptoms such as shortness of breath, wheezing and cough in patients with asthma or COPD and also help to prevent the symptoms of asthma.
