Bioequivalence of budesonide plus formoterol (BF) Spiromax® and BF Turbohaler® (with and without charcoal block) in healthy volunteers

These studies indicate that BF Spiromax (±charcoal block) is bioequivalent to BF Turbohaler with respect to the PK parameters assessed. Single doses of BF Spiromax were well tolerated; the overall safety profile of BF Spiromax and BF Turbohaler was similar.
