Claims15
A method of treating a skin disease susceptible to treatment with corticosteroid active substances, said method comprising administering topically to a patient in need thereof, an effective amount of a foamable pharmaceutical composition comprising a corticosteroid active substance, a quick-break foaming agent that comprises an aliphatic alcohol, water, a fatty alcohol and a surface active agent;
- a propellant;
- and a buffering agent present in an amount sufficient to provide a pH within the range of 3.0 to 6.0.
A method of treating a skin disease susceptible to treatment with corticosteroid active substances, said method comprising administering topically to a patient in need thereof an effective amount of a foamable pharmaceutical composition comprised of a quick-break foaming agent that comprises an aliphatic alcohol, water, a fatty alcohol and a surface active agent a propellant;
- an active isomer of an isomeric corticosteroid active substance;
- and an amount of a buffering agent effective to stabilize the active isomer against isomerization to a less active isomer.
