    摘要: The present invention relates to a pharmaceutical formulation for use in the administration of a long-acting β2-agonist by inhalation. In particular this invention relates to a chemically stable, highly efficient salmeterol HFA solution formulation to be administered by pressurised metered dose inhalers (pMDIs) characterized by a deep lung penetration. The invention also relates to methods for the preparation of said formulation and to its use in respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD).

    摘要: In a solution composition for use in an aerosol inhaler which comprises an active material, a propellant containing a hydrofluoroalkane, a cosolvent and optionally a low volatility compound the use of a mixture of HFA 134a and HFA 227 allows to modulate the mass median aerodynamic diameter (MMAD) of the aerosol particles on actuation of the inhaler to target specific regions of the respiratory tract. Moreover the fine particle dose (FPD) of the active ingredient in the composition increases by reducing the metering chamber volume.
