Tiotropium for Adults with Inadequately Controlled Persistent Asthma (January).

Ann Pharmacother. 2013 Jan 16;

OBJECTIVE:To review the literature evaluating the efficacy and steroid-sparing effect of tiotropium for inadequately controlled persistent asthma in adults.DATA SOURCES:Information was obtained through a search of MEDLINE/PubMed (1966-October 2012), using the terms asthma and tiotropium. A further review of reference citations was performed to identify other relevant articles.STUDY SELECTION AND DATA EXTRACTION:English-language case reports and clinical trials were reviewed. Publications evaluating the efficacy and steroid-sparing effect of tiotropium in adults with inadequately controlled persistent asthma were included in the review. One case report and 5 clinical trials met our criteria.DATA SYNTHESIS:The ultimate goal for asthma management is to maintain disease control by preventing acute exacerbations while avoiding adverse medication effects. Inhaled corticosteroids (ICS) are part of all preferred maintenance regimens for persistent asthma. Unfortunately, persistent asthma remains inadequately controlled in some patients and concerns about serious adverse effects with long-term high-dose ICS treatment exist. Interest in the use of tiotropium to control asthma symptoms and reduce steroid requirements in inadequately controlled persistent asthma is emerging. Results of several trials indicate that tiotropium improves pulmonary function markers and reduces corticosteroid requirements. Moreover, the largest and longest published trial not only showed improvements in pulmonary function tests but also a reduction in corticosteroid use and an increase in the time to first exacerbation.CONCLUSIONS:Although tiotropium use in treatment of persistent asthma appears to be promising, more robust clinical trials are needed to assess whether improved pulmonary function tests as well as a decrease in asthma exacerbations and corticosteroid requirements translate into improvements in quality of life. Additionally, the optimal patient population, long-term efficacy, and safety of tiotropium when delivered by various methods need to be determined before it can be recommended over current alternative asthma therapies.
