Fluticasone is used to control and prevent symptoms (such as wheezing and shortness of breath) caused by asthma. Controlling symptoms of asthma helps you maintain your normal activities and decreases time lost from work or school. Fluticasone belongs to a class of drugs known as corticosteroids. It works by reducing swelling (inflammation) of the airways in the lungs to make breathing easier. This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden asthma attacks.

Clinical Summary

A muscarinic antagonist structurally related to ATROPINE but often considered safer and more effective for inhalation use. It is used for various bronchial disorders, in rhinitis, and as an antiarrhythmic.

Therapeutic Applications

Ipratropium is used to control and prevent symptoms (wheezing and shortness of breath) caused by ongoing lung disease (chronic obstructive pulmonary disease-COPD which includes bronchitis and emphysema). It works by relaxing the muscles around the airways so that they open up and you can breathe more easily. Controlling symptoms of breathing problems can decrease time lost from work or school. For preventing symptoms of lung disease, this medication must be used regularly to be effective. Use your quick-relief inhaler (such as albuterol, also called salbutamol in some countries) for wheezing or sudden shortness of breath unless otherwise directed by your doctor. Ipratropium does not work as fast as your quick-relief inhaler, but may sometimes be used to relieve symptoms of wheezing or sudden shortness of breath if so prescribed by your doctor.
