Like N -acetylcysteine, it is not clear whether the saline washes are beneficial for CF patients. Back to Top Bronchodilators Bronchodilators are drugs that relax the muscles around the airways, causing the airways to open up and clear out. They are the most commonly prescribed medication for the treatment of asthma. Importantly, bronchodilators provide only temporary relief. Their long term benefits are unclear, although there is some evidence that they may slow the decline of lung function.
Most patients respond favorably.
Potential side effects include a fast heartbeat, nervousness, shakiness, nausea, and dizziness. Anticholinergics, such as ipatropium bromide, are an alternative to beta agonists. Theophylline is another bronchodilator that may, in selected cases, be beneficial, although generally its side effects outweigh its benefits. Side effects include nausea, vomiting, stomach cramps, diarrhea, headache, muscle cramps, irregular heartbeat, and feeling shaky or restless. It can also be used to treat patients with CF, although it is unclear whether its benefits for CF patients are as great as those for COPD patients.
