摘要:
The invention discloses an aerosol pharmaceutical composition comprising a medicament in solution in a mixture of a hydrfluoroalkane propellant and one or more co-solvents wherein the aerosol liquid droplets delivered on actuation of the inhaler have a particle size comprised between 0.5 μm and 2.5 μm, with a mass median aerodynamic diameter of about 1-2 μm and wherein the fine particle fraction is at least 30%.
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 formoterol 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).

The present invention relates to a pharmaceutical formulation for use in the administration of 2(1H)-quinolinone derivatives long-acting β2-agonists by inhalation. In particular this invention relates to a chemically stable highly efficient TA 2005 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:
An aerosol solution composition for use in an aerosol inhaler comprises an active material, a propellant containing a hydrofluoroalkane, a cosolvent and optionally a low volatility component to increase the mass median aerodynamic diameter (MMAD) of the aerosol particles on actuation of the inhaler. The composition is stabilized by using a small amount of mineral acid and a suitable can having part or all of its internal metallic surfaces made of stainless steel, anodized aluminium or lined with an inert organic coating.

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.
