Canisters containing aerosol formulations containing P134a and fluticasone propionate

A canister suitable for delivering a pharmaceutical aerosol formulation which comprises a container capable of withstanding the vapor pressure of the propellant used, which container is closed with a metering valve and contains a pharmaceutical aerosol formulation consisting of a particulate medicament consisting of fluticasone propionate or a physiologically acceptable solvate thereof and 1,1,1,2- tetrafluoroethane as propellant, the particulate medicament being present in an amount from 0.005% to 5% w/w relative to the total weight of the formulation and having a particle size of less than 100 microns.

A canister suitable for delivering a pharmaceutical aerosol formulation which comprises a container capable of withstanding the vapor pressure of the propellant used, which container is closed with a metering valve and contains a pharmaceutical aerosol formulation consisting essentially of:

• (i) particulate medicament which is fluticasone propionate or a physiologically acceptable solvate thereof;
• (ii) a particulate medicament selected from the group consisting of salmeterol, salbutamol, beclomethasone dipropionate and physiologically acceptable salts and solvates thereof;
• and (iii) 1,1,1,2-tetrafluoroethane as propellant, which formulation contains less than 0.0001% w/w surfactant based on the weight of the medicament, the particulate medicaments being present in an amount of 0.005% to 5% w/w relative to the total weight of the formulation and having a particle size of less than 100 microns.
