What is Uniphyl?

Theophylline sustained-release (theophylline SR) works by relaxing muscles in the lungs and suppressing the lungs from reacting to a lot of stimuli that can make it harder to breathe. Overall, theophylline SR opens the airways and makes it easier for people with lung issues to breathe.
