Abstract:
A pharmaceutical solution for a medication delivery apparatus, especially a metered dose inhaler, is described. The pharmaceutical solution comprises: (a) a liquefied propellant component consisting essentially of and preferably consisting entirely of 1,1-difluoroethane (R-152a); (b) ethanol; and (c) a drug component dissolved in the propellant/ethanol mixture consisting of at least one drug selected from the group consisting of beclomethasone dipropionate (BDP) and fluticasone propionate (FP).

Claim (Index 1):
A pharmaceutical composition comprising:\n (a) a drug in an amount of 0.01 to 4.0 weight % based on the total weight of the pharmaceutical composition, wherein the drug comprises at least one corticosteroid; (b) a propellant component consisting essentially of 1,1-difluoroethane (R-152a); and (c) a first amount of ethanol; wherein at least 95 weight % of the pharmaceutical composition is made up of the propellant component, the drug and the first amount of ethanol, the first amount of ethanol is an amount needed such that the pharmaceutical composition is in solution form, and the first amount of ethanol is less than a second amount of ethanol that is needed to dissolve the same amount of the drug where 1,1,1,2-tetrafluoroethane (R-134a) replaces the 1,1-difluoroethane (R-152a).
