  • Long-Acting Beta-Agonists in the Management of Chronic Obstructive Pulmonary Disease: Current and Future Agents

For patients with moderate-to-severe COPD, long-acting bronchodilators are the mainstay of therapy; as symptoms progress, guidelines recommend combining bronchodilators from different classes to improve efficacy. Inhaled long-acting b2-agonists (LABAs) have been licensed for the treatment of COPD since the late 1990s and include formoterol and salmeterol. They improve lung function, symptoms of breathlessness and exercise limita- tion, health-related quality of life, and may reduce the rate of exacerbations, although not all patients achieve clini- cally meaningful improvements in symptoms or health related quality of life. In addition, LABAs have an acceptable safety profile, and are not associated with an increased risk of respiratory mortality, although adverse effects such as palpitations and tremor may limit the dose that can be tolerated. Formoterol and salmeterol have 12-hour durations of action; however, sustained bronchodilation is desirable in COPD.

  • Novel Asthma Therapies: a Review
    30 Current Drug Therapy, 2012, 7, 30-35 Novel Asthma Therapies: A Review Preeti Chopra1, Inderpal Randhawa1,2 and Terry Chin2,* 1Department of Medicine, VA Greater Los Angeles Healthcare System/UCLA, USA; 2Department of Pediatrics, Miller Children’s Hospital, University of California, Irvine, USA Abstract: Objective: To describe novel medical therapies in asthma. Data Sources: A comprehensive Pub Med search was performed and studies published between 2000 and 2008 were reviewed. Updated studies from 2009 to 2011 were also included. A focus was placed on randomized, controlled studies. Results: Indacaterol, a once daily inhaled long acting beta 2-agonist (LABA) increased forced expiratory volume in 1 sec (FEV1) and resulted in prolonged bronchodilation. Ciclesonide, a pro-drug inhaled corticosteroid, has been shown to increase FEV1 as well as improve morning, evening, and site-measured peak expiratory flow (PEF) with fewer adverse effects. Fluticasone/formoterol (Flutiform), a combination inhaled corticosteroid and LABA, showed a reduction in severe exacerbations requiring hospitalization, increased FEV1, less rescue medication use and higher quality of life scores. Extra-fine beclomethasone with formoterol also appears promising. Several immunomodulating drugs are on the horizon. Roflumilast, an oral once-daily PDE-4 inhibitor, improved forced vital capacity (FVC) and reduced the need for rescue medication. There are encouraging results with mepolizumab and reslizumab, anti-leukin-5 monoclonal antibody preparations, in a specific subset of asthmatic patients. Other approaches such as anti-interleukin-5 receptor blockage and anti-interleukin-9 monoclonal antibodies are in the early stages of development. On the other hand, treatment directed toward anti-tumor necrosis factor in asthmatics has been disappointing.
