BACKGROUND Few data exist related to the impact of roflumilast on health care utilization. This retrospective study estimated 30-day hospital readmission rates between patients who did and did not use roflumilast among those with COPD hospitalizations. METHODS Data were from MarketScan, a large US commercial health insurance claims database. Patients aged ≥40 years with at least one hospitali...

BACKGROUND Roflumilast is approved in the United States to reduce the risk of COPD exacerbations in patients with severe COPD. Exacerbation rates, health care resource utilization (HCRU), and costs were compared between roflumilast patients and those receiving other COPD maintenance drugs. METHODS LifeLink™ Health Plan Claims Database was used to identify patients diagnosed with COPD who init...

BACKGROUND Roflumilast is the first phosphodiesterase-4 (PDE4) inhibitor to have been approved for the treatment of COPD. The anti-inflammatory profile of PDE4 inhibitors has not yet been explored in human lung tissues. We investigated the effects of roflumilast and its active metabolite roflumilast-N-oxide on the lipopolysaccharide (LPS)-induced release of tumor necrosis factor-alpha (TNF-α) a...

BACKGROUND Current evidence suggests that roflumilast is efficacious in treating COPD, especially in preventing the acute exacerbation of COPD. OBJECTIVES This study was designed to evaluate the clinical effects and safety of roflumilast in the treatment of stable COPD using randomized clinical trial (RCT) data. METHODS A MEDLINE, EMBASE, and Cochrane Controlled Trials Register search was c...

Roflumilast is a selective phosphodiesterase-4 (PDE-4) inhibitor that was approved by the US Food and Drug Administration in February 2011 for the management of chronic obstructive pulmonary disease (COPD). Literature was retrieved through PubMed using the terms "roflumilast" and "COPD". Reference citations from publications identified were also reviewed. All articles published in English using...

Roflumilast, a potent and selective phosphodiesterase 4 (PDE4) inhibitor, has been demonstrated to be an effective anti-inflammatory agent in airway inflammatory diseases. In the present study, we investigated the mechanism of anti-inflammatory effects of roflumilast in murine macrophage cell line RAW264.7 cells. Roflumilast inhibited NO, tumor necrosis factor (TNF)-alpha, and interleukin (IL)-...

BACKGROUND Chronic obstructive pulmonary disease (COPD) exacerbations are associated with declining lung function and health-related quality of life, and increased hospitalization and mortality. Clinical trials often poorly represent the elderly and thus have only partial applicability to their clinical care. OBJECTIVE To compare exacerbations, COPD-related health care utilization (HCU), and ...

We have investigated the bronchodilator and anti-inflammatory properties of roflumilast (3-cyclopropylmethoxy-4-difluoromethoxy-N-[3,5-dichloropyrid-4-yl]-benzamide), a novel, highly potent, and selective phosphodiesterase 4 (PDE4) inhibitor. Additionally, we compared the effects of roflumilast and its N-oxide, the primary metabolite in vivo, with those of the PDE4 inhibitors piclamilast, rolip...

BACKGROUND Roflumilast, a phosphodiesterase 4 inhibitor, has been approved for the prevention of chronic obstructive pulmonary disease (COPD) exacerbations. It is unclear which patients will have a favourable benefit-harm balance with roflumilast. Our aim was to quantitatively assess the benefits and harms of roflumilast (500 µg/day) compared with placebo. METHODS We used summary data release...

BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) have few options for treatment. The efficacy and safety of the phosphodiesterase-4 inhibitor roflumilast have been investigated in studies of patients with moderate-to-severe COPD, but not in those concomitantly treated with longacting inhaled bronchodilators. The effect of roflumilast on lung function in patients with COPD t...
