Budesonide. An appraisal of the basis of its pharmacoeconomic and quality-of-life benefits in asthma.

Budesonide is an inhaled corticosteroid that is used prophylactically to reduce the underlying inflammation and consequent airways narrowing associated with asthma. Widespread clinical experience has shown that inhaled budesonide is effective and well tolerated, and its use is well established in the management of adult and childhood asthma. In developed countries, asthma is a major health problem and consumes a large proportion of healthcare resources. Both the prevalence and severity of asthma appear to be increasing. Additionally, asthma-related mortality has been reported to have gradually increased since the mid- to late-1970s in many countries, possibly due to undertreatment and/or suboptimal management of the disease. Current guidelines recommend a shift away from initial treatment with oral bronchodilators, such as theophylline, or regular use of beta 2-agonist inhalers, toward the earlier use of more expensive inhalers containing corticosteroids. Inhaled bronchodilators are still used as indicated for treatment of acute attacks. Data suggest that the acquisition cost of budesonide is more than offset by decreased morbidity and reductions in costs associated with acute asthma exacerbations. Both once-daily administration and its administration in dry powder form via Turbuhaler appear to be well accepted by patients; these factors may potentially improve patient compliance with therapy. Budesonide appears to have positive effects on some quality-of-life indices, although studies using validated quality-of-life instruments are needed to confirm these conclusions. Modelling studies would be helpful in order to assess the possible economic benefits to society through reduction of the considerable direct and indirect costs of asthma and cost-effectiveness comparisons with other inhaled corticosteroids are needed to clarify its relative positioning in this regard. Until then, the available data provide an encouraging pharmacoeconomic rationale for budesonide as first-line asthma therapy, and a good basis for future pharmacoeconomic analysis of asthma management.
