The Effect of Type and Dosage of Newly Prescribed Inhaled Corticosteroids on Obstructive Lung Disease and Pneumonia Hospitalisations in Older Individuals with Asthma, Chronic Obstructive Pulmonary Disease (COPD) or Both: A Retrospective Study of Health Administrative Data.

The safety and risk-benefit profiles associated with different types and dosages of inhaled corticosteroids (ICS) in older individuals with asthma and COPD remain unknown [1, 2]. Limited evidence suggests that adults with asthma prescribed medium or high ICS doses are at risk of clinically important systemic side effects that do not plateau with higher doses as efficacy outcomes do [3]. Older patients with COPD have been shown to have increased risk of pneumonia with both budesonide and fluticasone [4]; however, the risk seems greater in the latter [2, 4–6].
