Budesonide/Formoterol or Budesonide/Albuterol as Anti-Inflammatory Reliever Therapy for Asthma

Abstract

Over use of reliever as short acting beta-agonist (SABA) and associated underuse of controller as inhaled corticosteroid (ICS) administered via separate inhalers results in worse asthma outcomes . Such discordance can be obviated by combining both controller and reliever in the same inhaler. So called anti-inflammatory reliever (AIR) therapy comprises the use of a single inhaler containing an ICS such as budesonide (BUD) in conjunction with a reliever as either albuterol (ALB) or formoterol (FORM) ,to be used on demand with variable dosing driven by asthma symptoms in a flexible patient centred regimen. Global guidelines now support the use of BUD-ALB as AIR therapy to reduce exacerbations , either on its own in mild asthma or in conjunction with fixed dose maintenance ICS-long acting beta-agonist (LABA) in moderate to severe asthma . Using BUD-FORM on its own allows patients to seamlessly move in an intuitive flexible fashion between AIR or maintenance and reliever therapy (MART) , by stepping up and down the dosing escalator across a spectrum of asthma severities . Head to head clinical studies are indicated to compare BUD-FORM versus BUD-ALB as AIR in mild asthma ,and also BUD-FORM as MART versus BUD-ALB as AIR plus maintenance ICS-LABA in moderate to severe asthma. Patients should be encouraged to make an informed decision in conjunction with their health care professional regarding the best therapeutic option tailored to their individual needs , which in turn is likely to result in long term compliance and associated optimal asthma control.
