Randomized Controlled Trial Multicenter StudyLong-term safety and asthma control measures with a budesonide/formoterol pressurized metered-dose inhaler in African American asthmatic patients: a randomized controlled trial.
Information surrounding the long-term safety of combination inhaled corticosteroid/long-acting β(2)-adrenergic agonist medications in African American asthmatic patients is limited. ⋯ In this population budesonide/formoterol pMDI was well tolerated over 12 months, with a safety profile similar to that of budesonide; the asthma exacerbation rate was reduced by 38.5% versus budesonide.
