Applications

1. Chronic Obstructive Pulmonary Disease (COPD)

Primary indication for reducing the risk of COPD exacerbations in patients with:

Severe COPD (FEV1 < 50%)

Chronic bronchitis phenotype

History of frequent exacerbations

Mechanism: PDE4 inhibition leads to increased cAMP in neutrophils, eosinophils, macrophages, and T cells, suppressing pro-inflammatory cytokine release and reducing airway inflammation.

2. Asthma (Investigational)

Studied for use in severe asthma, especially phenotypes with eosinophilic or neutrophilic inflammation.

Shows promise in combination therapy with corticosteroids.

3. Other Inflammatory Disorders (Preclinical/Research)

Being investigated for potential roles in:

Psoriasis

Pulmonary fibrosis

Inflammatory bowel disease (IBD)

Neuroinflammatory conditions such as multiple sclerosis or Alzheimer's disease

04

Benefits

1. Selective PDE4 Inhibition

Roflumilast丨CAS 162401-32-3 provides targeted anti-inflammatory activity in the lungs without affecting PDE1–3 or PDE5 pathways.

Reduces airway neutrophilic inflammation, complementing bronchodilators.

2. Oral Once-Daily Dosing

Convenient oral tablet, usually 500 µg once daily, improves patient adherence compared to inhaled therapies.

3. Steroid-Sparing Potential

Non-corticosteroid anti-inflammatory action reduces reliance on inhaled or systemic corticosteroids, which have more side effects.

4. Exacerbation Risk Reduction

Demonstrated efficacy in reducing moderate-to-severe COPD exacerbations, especially in high-risk patients with chronic bronchitis.
