Inhaler Use for Symptom Relief in Acute Bronchitis
Inhalers are commonly used to manage symptoms in acute bronchitis, especially cough and airway inflammation. Several studies have explored the effectiveness of different inhaled therapies, including bronchodilators, corticosteroids, mucolytics, and other inhaled solutions.
Inhaled Bronchodilators for Acute Bronchitis Cough
Research shows that inhaled bronchodilators, such as albuterol delivered by a metered-dose inhaler (MDI), can help reduce the duration of cough in patients with acute bronchitis. One study found that patients using albuterol MDI were less likely to still be coughing after 7 days compared to those using a placebo inhaler, regardless of smoking status or antibiotic use . This suggests that bronchodilators can provide meaningful symptom relief for acute bronchitis.
Inhaled Corticosteroids and Combination Therapies
Inhaled corticosteroids, often combined with long-acting beta-agonists (ICS-LABA), are also used in acute bronchitis. A recent study reported that most patients experienced cough resolution within about 9 days when treated with inhaled therapies, and patient satisfaction and quality of life improved significantly . These findings support the use of inhaled corticosteroids and combination inhalers for managing acute bronchitis symptoms.
Inhaled Mucolytics and Expectorants
Inhaled mucolytics, such as N-acetylcysteine and ambroxol, have been shown to provide faster relief and disappearance of cough in children with acute bronchitis compared to oral mucolytics. Inhaled therapy also led to quicker improvement in related symptoms like rhinitis and sore throat . Similarly, in adults with acute exacerbations of chronic bronchitis, inhaled ambroxol was more effective and had fewer adverse effects than a regimen including dexamethasone and chymotrypsin .
Ectoine and Saline Inhalation Solutions
A study comparing ectoine-containing inhalation solution to saline found that both treatments reduced symptom scores in acute bronchitis, but ectoine led to slightly faster and greater improvement. Both treatments were well tolerated . This suggests that inhaled solutions, even without active bronchodilators or steroids, can help relieve symptoms.
Inhaler Device Effectiveness During Acute Bronchoconstriction
Concerns about the ability to use dry powder inhalers (DPIs) during acute bronchoconstriction have been addressed in recent research. Most patients, even during acute episodes, can generate sufficient inspiratory flow to use DPIs effectively . Additionally, salbutamol delivered via DPI was found to be as effective as a pressurized MDI with spacer in relieving acute bronchoconstriction, supporting the use of DPIs in acute settings .
Clinical Guidelines and Recommendations
Clinical guidelines emphasize that acute bronchitis is usually viral, and antibiotics are not recommended. Instead, inhaled therapies—especially mucoactive drugs and bronchodilators—are suggested for symptom relief, particularly for cough. Combination inhalers containing bronchodilators and mucolytics have shown the most pronounced effect in reducing cough duration .
Conclusion
Inhaler use in acute bronchitis, including bronchodilators, corticosteroids, mucolytics, and other inhaled solutions, is effective for reducing cough and improving patient comfort. Inhaled therapies generally provide faster symptom relief than oral medications and are well tolerated in both children and adults. Device choice (MDI or DPI) does not significantly impact effectiveness during acute episodes, and inhaled treatments are a key part of symptomatic management for acute bronchitis 12356789.
