Treatment Approach for Bronchitis Symptoms

Diagnosis and Definition

Chronic bronchitis is defined as daily expectoration for at least 3 consecutive months during at least 2 consecutive years, and may be classified as simple chronic bronchitis or obstructive chronic bronchitis based on symptoms and airflow limitation 1

For dry, bothersome cough, Dextromethorphan can be prescribed, as there is evidence of its effectiveness for acute cough 2
For cough associated with common cold, a first-generation antihistamine plus decongestant may decrease cough severity 3

Ipratropium bromide is recommended as first-line therapy to improve cough in stable chronic bronchitis patients 4
Short-acting β-agonists, like albuterol, can be used to control bronchospasm and may reduce chronic cough in some patients 4
Theophylline may be considered to control chronic cough, but requires careful monitoring for complications 4

For patients with severe airflow obstruction or frequent exacerbations, inhaled corticosteroids combined with long-acting β-agonists are recommended 5
Long-term oral corticosteroids are not recommended due to lack of benefit and significant side effects 5, 6

Avoidance of respiratory irritants, especially smoking cessation, is crucial, and can lead to resolution of cough in 90% of patients with chronic bronchitis 5
Short-term use of central cough suppressants like codeine or dextromethorphan may provide relief for troublesome cough in chronic bronchitis 6

Prescribing antibiotics for uncomplicated acute bronchitis contributes to antibiotic resistance, and antibiotics should not be prescribed unless pertussis is suspected or the patient is at high risk for pneumonia 7
Using expectorants without evidence of benefit, as currently available expectorants have not been proven effective for cough in chronic bronchitis 6

The American Thoracic Society recommends determining whether the patient has acute bronchitis or an acute exacerbation of chronic bronchitis (AECB) to guide management, particularly regarding antibiotic use 8
The American College of Chest Physicians suggests ruling out pneumonia by assessing for heart rate >100 bpm, respiratory rate >24 breaths/min, temperature >38°C, and focal consolidation on chest exam, as the absence of all four makes pneumonia unlikely enough to avoid chest radiography 9
In patients with recurrent "acute bronchitis" episodes, consider that 65% actually have underlying mild asthma or will develop chronic bronchitis/COPD, according to the American Thoracic Society 10

The American College of Chest Physicians recommends that antibiotics should NOT be prescribed routinely for acute bronchitis, as it is viral in >90% of cases and antibiotics provide minimal benefit while causing harm through adverse effects and resistance 10, 9
The American Thoracic Society suggests that smoking cessation counseling is mandatory, as it is the single most effective intervention, with 90% of patients experiencing cough resolution after quitting 8
For acute exacerbation of chronic bronchitis (AECB), antibiotics are indicated, particularly in elderly patients with risk factors, according to the American College of Chest Physicians 8
The American Thoracic Society recommends monitoring for worsening of acute bronchitis and reconsidering bacterial superinfection and antibiotic therapy if necessary 10
