title: The economic aspects of drug delivery in asthma.
abstract: The need for cost-effective asthma therapy is driven by the high prevalence of asthma as well as the high cost of both medical care and lost productivity through illness. Limited healthcare resources demand proven therapies that maintain sustained disease control. Optimal disease control is the essence of cost effectiveness, but this in turn is dependent on correct drug selection and appropriate drug delivery. Successful treatment depends on delivery of medication to the site of action in the airways. Although there is a substantial number of aerosol delivery systems available, there is considerable confusion as to the most suitable method in different clinical settings, and across different age groups. Optimal drug delivery can be achieved without adding substantially to the overall cost of therapy. Both drugs and delivery systems need to be individualised to the needs of the patients. The early introduction of oral corticosteroids for acute exacerbations has resulted in reduced hospitalisation and shortened illness, providing substantial cost savings. A reduction in the reliance on nebuliser therapy in both the acute and chronic setting will further optimise therapy and reduce costs. We have reviewed the current literature to determine the most cost-effective methods of drug delivery in asthma.
