    Abstract: A pharmaceutical composition containing a microemulsion made up of a hydrophilic component, a lipophilic component, a surfactant and a drug, where the hydrophilic component, the lipophilic component and the surfactant form, when examined on a macroscopic scale, a one-phase solution. The hydrophilic component is dispersed as colloidal droplets in the lipophilic component, or the lipophilic component is dispersed as colloidal droplets in the hydrophilic component. According to still another alternative, the hydrophilic and the lipophilic components form a microemulsion with bicontinuous structure where the components form elongated adjacent channels. The drug is dissolved in the dispersed component or, in the case of a microemulsion with bicontinuous structure, in the hydrophilic or the lipophilic component. The microemulsion is stabilized by means of the surfactant. It is characteristic that a gelatinizer and water are added to the microemulsion thereby bringing the microemulsion into a gel form.
