A composition comprises a mixture of a silicone and a first solvent, a drug, such as a hydrophilic or lipophilic pharmaceutical agent, a salt of a dialkyl sulfosuccinate, such as dioctyl sodium sulfosuccinate (DOSS), and a second solvent, such as an alcohol. The salt of a dialkyl sulfosuccinate solubilizes the drug. The composition can be topically applied to a substrate, such as skin, for delivering the drug. Drugs with a wide solubility range are soluble and compatible in the composition without separation or crystallization of the drugs occurring.
