摘要:
The invention provides a formulation to be administered as a dry powder for inhalation suitable for efficacious delivery of active ingredients into the low respiratory tract of patients suffering from a pulmonary disease such as asthma. In particular, the invention provides a formulation to be administered as dry powder for inhalation freely flowable, which can be produced in a simple way, is physically and chemically stable and capable of delivering both accurate doses and high fine particle fraction of low strength active ingredients by using a high- or medium resistance device.
摘要:
A powder for use in a dry powder inhaler comprises: i) a fraction of fine particle size constituted by a mixture of physiologically acceptable excipient and an additive; ii) a fraction of coarse particles; and iii) at least one active ingredient. The powder is suitable for efficacious delivery of active ingredients into the low respiratory tract of patients suffering from pulmonary diseases such as asthma. In particular, the invention provides a formulation to be administered as dry powder for inhalation which is freely flowable, can be produced in a simple way, is physically and chemically stable and capable of delivering accurate doses and/or high fine particle fraction of low strength active ingredients by using a high- or medium resistance device.

摘要:
A formulation for an inhaler device comprises carrier particles having a diameter of at least 50 μm and a mass median diameter of at least 175 μm; active particles; and additive material to which is able to promote release of the active particles from the carrier particles on actuation of the inhaler device. The formulation has excellent flowability even at relatively high fine particle contents.

摘要:
A metered-dose inhaler includes at least one vessel and an actuator for receiving the at least one vessel. The at least one vessel includes a first reservoir containing a first formulation and a second reservoir containing a second formulation. The metered-dose inhaler is actuable when the at least one vessel is received by the actuator. The metered-dose inhaler is configured to simultaneously deliver a first metered dose of the first formulation and a second metered dose of the second formulation upon actuation.
摘要:
A device for delivering metered aerosols g an active ingredient in solution in a propellant consisting of a hydrofluoroalkane (HFA), selected from 1,1,1,2-tetrafluoroethane (HFA 134a), 1,1,1,2,3,3,3-heptafluoropropane (HFA 227) or mixtures thereof, a co-solvent such as ethanol and optionally a low-volatility component preferably selected from glycerol, propylene glycol polyethylene glycol, oleic acid and isopropyl myristate, said device comprising a flat body with a seat for housing the can, an inhalation mouthpiece and an expansion chamber shaped to create a vortex flow of the aerosol particles expelled by the actuator, wherein the actuator orifice diameter is in the range between 0.30 and 0.50 mm.
