Generic Name: aminophylline (am-in-AHF-ih-lin)
Brand Name: Generic only. No brands available.
Aminophylline is used for:
Treating active symptoms and blockage of airway due to asthma or other lung diseases such as emphysema or bronchitis. It is used in combination with other medicines.
Aminophylline is a xanthine derivative. It works by relaxing the smooth muscle surrounding the bronchial tubes (air passages) of the lungs, allowing the tubes to widen, making breathing easier. Aminophylline improves contraction of the diaphragm (the major breathing muscle).
Do NOT use aminophylline if:
- you are allergic to any ingredient in aminophylline (including ethylenediamine), similar medicines (eg, theophylline), or xanthines (eg, caffeine, chocolate)
- you are using large amounts of other products that contain xanthine (such as chocolate or caffeinated drinks)
- you are taking dipyridamole intravenously (IV) or halothane
Contact your doctor or health care provider right away if any of these apply to you.
