摘要:
The present invention relates to pharmaceutical compositions comprising the antimuscarinic agent glycopyrrolate, for example the salt glycopyrronium bromide. In particular, the present invention relates to dry powder compositions which exhibit improved stability over time, and methods for producing the same.
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).
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:
A medicinal aerosol product comprising a pressurized metered dose inhaler, including a canister equipped with a metering valve and containing a medicinal aerosol solution formulation, and an actuator comprising a nozzle block defining an actuator orifice s leading to an expansion chamber, wherein the formulation includes a cannabinoid, a hydrofluorocarbon propellant and an optional amount of an alcohol co-solvent, and the actuator orifice has a diameter of about 0.30mm or less, and/or is laser drilled.
摘要:
Emulsion and microemulsion aerosol formulations in a HFA propellant system include a medicament, one or more surfactant, optionally a cosolvent and water. Emulsion formulations are based on 0.1-% w/w surfactant and 1-10% w/w water. Microemulsion formulations are based on 1-20% w/w surfactant, 1-30% w/w cosolvent and 1-10% w/w water. Preferred surfactant are Span 85, AOT and their blends, synperonics and alkylpolyglucosides (APGs) The preferred cosolvent is ethanol.
摘要:
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).
