Roflumilast in Non-CF Bronchiectasis Study

Roflumilast, a phosphodiesterase 4 (PDE4) inhibitor is approved worldwide (including Hong Kong) for treatment of severe chronic obstructive pulmonary disease (COPD) with frequent exacerbations. Roflumilast has been shown to have anti-inflammatory effect in patients with COPD, with significant reduction of sputum absolute neutrophil count, IL-8 and neutrophil elastase compared with placebo treatment. Roflumilast can also improve the lung function parameters in patients with COPD and reduce the rate of moderate-to-severe exacerbations.
