Microemulsions as drug delivery vehicles

Microemulsions offer many promising features for their possible widespread use as vehicles for the delivery of drugs, as is evidenced by the recent introduction to the market of a microemulsion pre-concentrate for the oral delivery of cyclosporin. This vehicle has stimulated considerable interest in microemulsions and related systems, such as microemulsion-based lecithin gels. Much work is being centered around producing drug-containing microemulsions from materials that are suitable for use in humans.
