The invention relates to pressurized gas formulations for dosage aerosols, in which a medicament is formulated suspended in TG 227 ea (1,1,1,2,3,3,3-heptafluoropropane) and/or TG 134 a (1,1,1,2-tetrafluoroethane) as a propellant, and to their use for producing a medicament. The aerosol is preferably an inhalation aerosol.

Aerosol suspension formulations with TG 227 ea or TG 134 a as propellant

Pharmaceutical preparations for producing powder aerosols using propellant gases which use TG 227, and possibly also TG 11, TG 12, TGH 114, propane, butane, pentane or DME.

Suspension aerosol formulations of pharmaceutical products

New advantageous propellent gas mixtures contain two or more components, at least one of which is a partially fluorinated lower alkane, and may be used in pharmaceutical preparations.

Pharmaceutical composition using a mixture of propellant gases for a metered dose inhaler

A metering valve for a pressurized dispensing container. The container is intended to operate in the inverted position. An element having a raised peripheral portion is provided about the valve housing which substantially closes the space between the wall of the container and the valve housing. The element prevents the settling of active substances of the material being dispensed in the region of the inlet opening of the metering valve.
