Dataset from A Randomised, Open Label, Five-way Crossover Study to Assess the Systemic Exposure of Fluticasone Propionate and Salmeterol From SERETIDE/ADVAIR 250HFA MDI Alone and With AeroChamber-Max Spacer and VOLUMATIC Both in Their Washed and Unwashed States in Adult Subjects With Mild or Intermittent Asthma

Spacers are used by people with respiratory diseases who have problems using MDIs (metered dose inhalers). This study used fluticasone propionate/salmeterol to look at the pharmacokinetic profiles produced by different spacers in their washed and un-washed states.
