Successful treatment of previously uncontrolled adult asthma with budesonide inhalation suspension: five-year case histories.

Objective: To determine whether nebulized budesonide inhalation suspension (BIS) is effective in treating adults with asthma that has been uncontrolled by inhaled therapies.

Case Summaries: Three adults with severe persistent asthma were switched to BIS after poor outcomes with other controller medications, including inhaled corticosteroids (ICSs). BIS dosages were initiated with 1 mg twice daily. Based on physician discretion as symptoms improved, dosages were decreased to 0.5 mg twice daily (2 pts.) or once daily (1 pt.). Patients were instructed to self-manage their asthma, increasing their dosages during periods of asthma worsening. Peak expiratory flow (PEF) was assessed before and after the initiation of BIS. The number of healthcare visits and oral corticosteroid courses recorded in patient medical records during the 3 years before and 5 years after initiation of BIS therapy were compared. In all 3 cases, BIS improved asthma control. BIS consistently increased PEF and reduced the number of urgent care visits and oral corticosteroid courses. All patients reported satisfaction with BIS therapy.

Discussion: Despite proven effectiveness of ICSs for persistent asthma, some patients fail to respond optimally to treatment administered via an inhaler. These 3 case reports suggest that BIS is effective in treating adults with severe persistent asthma who fail to respond optimally to treatment with other ICS preparations. Failure to use inhalers properly, previous poor adherence in 1 case, or patient preference for the nebulizer might explain why nebulized BIS was more effective than other inhaler therapies.

Conclusions: Switching adults with uncontrolled asthma to BIS therapy may be a valuable treatment option for those who are unable to achieve optimal asthma control, despite asthma education and training on inhaler technique.
