Symbicort: a pharmacoeconomic review

Abstract

Objective: This systematic review examines the published evidence on the pharmacoecomonics of Symbicort®. Symbicort is a combination inhaler used in asthma and chronic obstructive pulmonary disease (COPD) that contains budesonide and formoterol. In asthma, Symbicort can be used as fixed or adjustable dose maintenance therapy as well as for both maintenance and reliever therapy (SMART).

Method: A literature search of PubMed was carried out to find all publications on the pharmacoeconomics of Symbicort. Additional studies were searched for in the reference lists of the papers retrieved and by searching tables of contents of relevant journals. A total of 13 studies on Symbicort in asthma and 2 studies on Symbicort in COPD were found.

Results: Total costs were lower with Symbicort than with separate inhalers containing budesonide and formoterol. Adjustable dosing maintained control of asthma using less medication and was associated with lower treatment costs than fixed dosing with Symbicort or the combination of fluticasone/salmeterol. SMART improves asthma control, reduces exacerbations and reduces direct and indirect costs compared to fixed maintenance therapy with either Symbicort or fluticasone/salmeterol. In COPD, Symbicort offers clinical advantages over therapy with the monocomponents and these are achieved at little or no extra cost.
