Abstract
Provided are oil-in-water microemulsions for formulating pharmaceutically active compounds. The microemulsions contain oils, surfactants, water, and the pharmaceutical compounds, and are produced by mixing an aqueous phase and a lipid phase in which each phase contains at least one surfactant in a defined ratio whereby the resulting microemulsion has very small dispersed particles and is thermodynamically very stable.
