Background: Since allergic rhinitis in asthma patients is associated with worse asthma control, the treatment of the comorbid condition may improve outcomes. Methods: A 1-year retrospective study using the UK Mediplus database (2001–2004) included asthmatic patients aged 15–55 with allergic rhinitis. Patients starting therapy based on the Global Initiative for Asthma guidelines, defined as an increase in inhaled corticosteroids (high-dose inhaled corticosteroids, hdICS), or the addition of montelukast (ICS+MON) or longacting -agonists (ICS+LABA) to ICS, were studied. Univariable and multiple logistic regressions evaluated asthma-related outcomes. Results: Among 2,596 asthma and allergic rhinitis patients, 83.2% initiated ICS+LABA, 12.1% hdICS and 4.7% ICS+MON. The mean age was 34 years and 60% were female. ICS+MON patients had more moderate-severe asthma (p = 0.04). Approximately 84% of the ICS+LABA patients experienced an asthma control failure compared to 50% in the other groups (p ! 0.0001). The proportions of patients requiring treatment change were 73.8, 22 and 27.3% in the ICS+LABA, hdICS and ICS+MON groups, respectively (p = 0.001). Asthma-related resource use was similar among all groups. The ICS+MON group received fewer mean prescriptions for oral corticosteroids (p = 0.024) than the other groups (p = 0.026). Conclusions: In asthma and allergic rhinitis, treatment with ICS+MON or hdICS was associated with lower rates of asthma control failure and fewer treatment changes than the ICS+LABA group. MON users also required fewer oral corticosteroids.
