Background And Objective: Roflumilast, an oral, selective phosphodiesterase 4 inhibitor, has been shown to reduce exacerbations and improve pulmonary function in patients with COPD. This study examined the efficacy, safety and tolerability of roflumilast in Asian patients with COPD.
Methods: Patients with COPD were randomized 1:1 to enter a 12-week treatment period and receive either oral roflumilast, 500 µg once daily, or placebo, following a single-blind, 4-week baseline period in which all patients received placebo.
