'''Budesonide/formoterol''' is a combination formulation containing [[budesonide]] and [[formoterol]] used in the management of [[asthma]] and [[chronic obstructive pulmonary disease]] (COPD) in the EU. It is marketed by [[AstraZeneca]] under the trade name '''Symbicort'''. Symbicort in the United States is a pressurized metered-dose inhaler while in the EU, Australia, Canada, Israel, and elswhere Symbicort is available as a dry-powder inhaler.
Symbicort contains two active ingredients which are delivered via a single inhaler:
* [[budesonide]] (Pulmicort), an anti-inflammatory [[corticosteroid]]
* [[formoterol]] (Oxis, Foradil), a rapid-acting and long-lasting [[bronchodilator]]
In Europe, Symbicort is available in doses of 100/6, 160/4.5, 200/6, 320/4.5 and 400/12, where the larger number is the dose per actuation of budesonide (in [[microgram]]s) and the lower number the dose of formoterol. In the United States, Symbicort is available in 160/4.5mcg and 80/4.5mcg per actuation.
Symbicort was introduced in [[Sweden]] in 2000 and is approved for use in at least 70 countries, yielding global sales in excess of $1 billion in 2005. It was not approved for use in the United States until July 2006.<ref>{{cite news

Symbicort is the first combination [[inhaled corticosteroid]]/[[Long acting beta-adrenoceptor agonist|long-acting beta agonist]] (ICS/LABA) that has shown some efficacy as a medicine not only used to prevent asthma attacks, but also provide quick relief of an asthma attack.<ref>{{cite journal

}}</ref>, although the role of budesonide in these cases is questionable.
The use for quick relief has been approved by the GINA guidelines 2006 (Evidence A) however Symbicort is indicated in the United States only as a maintenance medication.
In patients with asthma, Symbicort for both maintenance and as needed treatment reduces exacerbations better than as needed formoterol or as needed terbutaline. Nevertheless, it is unclear whether this strategy is better than increasing a maintenance dose of Symbicort or similar combined inhaler.<ref> Klaus F.
