What is theophylline?

ANSWER

Theophylline is a relatively weak but inexpensive bronchodilator containing a chemical similar to caffeine. Theophylline relaxes the smooth muscle that surrounds the airways.

Theophylline is sold as a generic pill or under the brand names Uniphyl and Theo-24. Theophylline is available as an oral (pill and liquid) or intravenous (through the vein) drug. Theophylline is available in short and long-acting forms and prevents asthma symptoms, especially nighttime symptoms. It is used less often for asthma, because it requires blood-level monitoring.
