Summary:

      Brief Summary:

      The primary objective was:

        -  to assess the bioequivalence of a single dose (two inhalations) of the test product
           compared to the reference product, with and without charcoal blockade.

      The secondary objectives were:

        -  to assess the pharmacokinetic profile of budesonide and formoterol in plasma after a
           single dose (two inhalations) of the test product and the reference product, with and
           without charcoal blockade.

        -  to assess the safety and tolerability of the test product and the reference product,
           with and without charcoal blockade.
