COMBINATION OF THERAPY FOR COPD

摘要

Aerosol formulations comprising glycopyrronium bromide in combination with formoterol are useful for the prevention or treatment of chronic obstructive pulmonary disease. The formulation further comprises a HFA propellant, a co-solvent, and an amount of inorganic acid sufficient to stabilize both the glycopyrronium bromide and the formoterol components. Optionally the formulation may further comprise beclometasone dipropionate.
