Effectiveness

How Theo-Dur Affects PatientsTheophylline, which is similar to caffeine and theobromine, is used to treat asthma and other airway problems. It helps by relaxing the airway muscles and reducing the body's response to irritants.
How Theo-Dur works in the bodyTheophylline is a medication that helps to open up the airways and reduce the responsiveness of the airways to various triggers. It does this by blocking an enzyme that breaks down a molecule in the cells that help keep the airways relaxed. It also binds to a receptor in the airways and prevents it from tightening. In inflammatory states, it helps reduce inflammation by stopping the transcription of certain genes.

I'm not sure if this medication contributed to my son's current health problems, but I've always wondered. We were desperate for something to help his asthma when he was younger and felt we had no choice. It did seem to help prevent wheezing at the time, but he's 30 now and has health problems and depression.

For years I was told this medicine was a steroid, and I took it for extended periods of time. As a result, I became overweight and have been struggling with my weight ever since. Additionally, I still had to go to the hospital several times for asthma issues.
