Microemulsions as delivery systems

Solubilization capacity, dissolution efficiency, rate and extent of solute delivery are dependent on the microemulsion microstructure.

Schematic presentation (not to scale) of possible packing of drug along dilution line N60 at the different dilution regions: water-in-oil, bicontinuous, and oil-in-water microemulsions. N60 means that the weight ratio of oil/mixed surfactants equals 4/6.Figure optionsDownload high-quality image (93 K)Download as PowerPoint slideHighlights
► Microemulsions are solubilization capacity enhancers and dissolution rate improvers.
► Microemulsions are generators of drug delivery systems.
► Microemulsions are delivery systems themselves.
