Abstract
Novel topically applicable oil-in-water emulsions, with a high proportion of oily phase in the inner phase, combine the occlusive and emollient properties of an ointment without having the drawbacks of a greasy feel, while at the same time promoting the therapeutic properties of a biologically active agent contained therein; such emulsions are especially useful for the treatment of dermatological diseases, conditions or afflictions, notably psoriasis.
