Is Theophylline a Bronchodilator for Relieving Asthma Symptoms?
Theophylline is a relatively weak but inexpensive bronchodilator that has a chemical similar to caffeine. Theophylline stimulates the heart, the central nervous system, and the skeletal muscles, while also relaxing the smooth muscles, including the airway muscles. Theophylline is sometimes used along with an anti-inflammatory drug to prevent nighttime asthma symptoms. Theophylline is sold as a generic pill or under the brand names Uniphyl, Theo-Dur, Slo-Bid, and Theo-24. Theophylline is available as an oral (pill and liquid) or intravenous (through the vein) drug. Theophylline is long-acting and prevents asthma attacks. Theophylline is used to treat difficult-to-control or severe asthma and must be taken daily.
