Asthma: Foster is indicated in the regular treatment of asthma in adult patients in whom: asthma is not adequately controlled by using inhaled corticosteroids and 'as needed' short-acting bronchodilators; or asthma is responding well to treatment with both corticosteroids and long-acting bronchodilators.
COPD: Foster can also be used to treat the symptoms of severe chronic obstructive pulmonary disease (COPD) in adult patients. COPD is a long term disease of the airways in the lungs which is primarily caused by cigarette smoking.
