Pharmaceutical compositions for aerosol delivery comprising (a) a medicament, (b) a non-chlorofluorocarbon propellant, and (c) a polyglycolized glyceride having a hydrophilic lipophilic balance of between and including 6 and 14, wherein the medicament is present in a concentration of between about 0.05% and about 5% by weight and the polyglycolized glyceride is present in a concentration of between about 0.001% and about 10% by weight, the nonchlorofluorocarbon propellant is selected from the group consisting of HCFC 123, HCFC 124, HCFC 141b, HCFC 225, HCFC 125, FC-C 51-12, DYMEL A, DYMEL 152a, HFC 134a and HFC 227ea in which unwanted aggregation of the medicament is prevented without the use of surfactants, protective colloids or cosolvents.
